-
- Welcome to yet another irregular issue of the Biosphere Newsletter. In
- this issue, I will attempt to keep the file/newsletter size down to about
- 500 lines or less, in the interest of network traffic. Therefore, in order
- to pack more in, I have had to try and make articles as brief as I can, which
- I find hard to do. This also means that headers and the like, will be kept to
- the bare minimun, (which they always were anyway). However this policy is in
- keeping with using resources efficiently and so has it's environmental merits.
-
- The topics that I have selected to write about this time around are an
- attempt by me to try and bring focus to the main problems facing the Biosphere
- and to introduce an article on a problem/area/region which hasn't been covered
- all that widely by other publications, so that we can help bring other
- diasters to your attention/interest. It is important to note, that which is not
- been reported on the news is just as relevant, and it is vital that some effort
- be made to bring as much (news) as possible to everybody's notice.
-
- Therefore in keeping with this line of thought I have introduced a new
- section which simply lists some interesting articles that I have recently come
- across. Finally feel free to make copies of this file/newsletter.

-
- 1) Lake Baikal - Siberia, USSR.
-
- Lake Baikal, largely unknown in the West, is perhaps the most fascinating lake
- on Earth. It is situated in eastern central Siberia in the USSR, (52N,107E)
- just north of Mongolia. It is by far the oldest and deepest lake in the world.
- The vast majority of lakes are no more than about 20,000 years old, but it is
- estimated that Lake Baikal is 20 to 50 MILLION years old. The lake forms part
- of a rift valley and plungs to a depth of over 1637 metres ( >5000ft), and while
- in terms of it's surface area, at 34,000 sq km, it ranks only seventh largest.
- However because of it combination of depth and size, it holds the greatest
- volume of freshwater in the world, in fact more than the five Great Lakes in
- North America.
-
- The Lake is over 650 kilometres long and is flanked on both sides by high
- mountains, which are covered by vast areas of forest. There are over 300 rivers
- of all sizes feeding into the lake, but only one river drains from it - and
- that is the Angara River which is at the southern end of the lake. But it is
- not only the geography of the lake, but the ecology in and around it, that
- makes Lake Baikal the most interesting lake on Earth. Whereas for nearly all
- other lakes, they are so young, the plants and animals that live in them have
- had not time to evolve with the lake. In the case of Lake Baikal, there has
- been ample time. Baikal is rich in both in terms of biomass and number of
- species - 1550 species and variants of animals and 1085 of plants - of which
- more than 1000 are found nowhere else. Because of the unique circulation
- patterns within Baikal, surface water (carrying oxygen) can reach the lake
- bottom and the result is that in the rich sediments below, the lake floor is
- teeming with life. Without exception there are almost no other lakes, where
- life exists at depths lower than 200 or 300 metres.
-
- The lake more or less survived intact up to the middle of this century, then
- logging and industrialization began. Between 1958 and 68, 1.5 million cubic
- metres of logs ended on the lake bottom, clogging many rivers. The bacteria
- from the decaying wood, starved the water of oxygen and in time over 10 streams
- and rivers had disappeared, because of damage to the hydrologly of the soil from
- the loss of tree cover. Large areas of the the shore and mountains around the
- lake suffered from erosion and many native fish were unable to spawn anymore
- in over 50 tributaries. Eventually some measures were taken taken to counteract
- this damage, such as tree planting. But the damage had already been done, and
- to add insult to injury, a significant amount of the timber was lost, when it
- was 'rafted' down the lake. These timber rafts often collided and the timber,
- left unattended -waterlogged, causing much of it to sink.
-
- On the industrial front, a new pulp mill was opened in the early 60's at
- Baikalsk, which is probably still one of the biggest polluters of the lake
- even today. Even though, there are still over 100 factories operating along
- the shore, which still have no purification facilities of any kind, (as of
- last year, and it's hardly any different this year), and the fact that between
- them it is estimated they discharge millions of tonnes of effluent into the
- lake, laden with metals like, mercury, zinc, tungsten, molybedenum, which
- competes with the agriculture complexes on the lake discharing pesticides,
- slurry and fertilisers, the pulp mill at Baikalsk, over it's life so far, is
- thought to have had just over half the total volume of Lake Baikal through
- it's plant and discharged out again.
-
- The plant at Baikalsk, was originally built to make use of the very pure
- water of Baikal, for making high quality cord/fibre for aircraft tyres, which
- was later superseded by Nylon. In 1961, the director of the Limnological
- Institute - Grigory Galazy warned that the mill would be a disaster and that it
- should be built at Bratsk, 600 km down the Angara river away from the lake,
- where the water was just as good also. But it was to no avail, and for the
- first few years of operation the plant discharged a steady flow of a black
- slimy waste. Within 18 months 400 tonnes of toxic waste had entered the lake
- and alkaline sludges began to form on the lake. One of the sludges was so big
- it grew to 30 kilometres length and persisted for months. During the early
- years of operation, the mill used 14 million litres of water a HOUR and thus
- discharged this same amount too. This volume is comparable to the amount of
- water used by a city such as Los Angles. Naturally enough soon the mill which
- had been built because it needed Baikal's pure water, was taking in it's own
- waste. So then the Soviets spent a fortunate installing equiment to purify
- incoming water, and the mill was eventually downgraded to production of paper
- which didn't require the same purity of water as before. Against this back-drop
- the mill had also received between 1968 and 71 a temporary award which allowed
- it operate on lower standards while the above equiment was installed. And when
- they finally had completed the installation, the level of pollution continued
- to increase. Nevertheless after many years and alot of money attempting to
- raise the standards of this giant paper mill, today 23 years later, it is still
- ejecting 230,000 cubic metres of waste water into the lake. It was G. Galazy,
- (see earlier) who estimated that the plant has discharged over 1.5 billion
- cubic metres of effluent into the lake and that about 15,000 CUBIC KILOMETRES
- of water - roughly half the lake's volume - has circulated through the paper
- mill, thus destroying it's pristine state.
-
- While many may be wondering why the paper mill was not shut long ago, it is
- because of largely the dependices it has brought on those who live near it. The
- local where the Baikalsh mill is situated has 30,000 people, nearly all of
- whose livelihoods would be destroyed if it were to close. And a facility as
- large as this is also bound to have people with influence and self interest to
- match. Therefore taming such as monster is never easy.
-
- If things then do not seem bad enough yet, air pollution is now beginning to
- become a more serious problem that water pollution around Lake Baikal. One
- would not think this could be possible but unfortunately the evidence is to
- be found in the mountains and forest's of the lake. Vegetation is under
- severe stress in some areas and disappearing. At risk are some of the plants
- that are to be found only in this area. For example, in 1985, in the Irtutsk
- region to the west of the lake where Baikalsk is located, and adjoining the
- huge Irkutsk-Cheremkhovo industrial area, more than 1.2 million tonnes of
- air pollution were released, while in the region east of the lake - Buryat,
- where another major polluting mill is located at Selengisk, a further 200,000
- tonnes were released.
-
- One would get the impression, that there are no laws governing pollution and
- the environment in the USSR, but in fact they have some quite tough laws. The
- problem is with resources, lack of law enforcement, bureaucracy, the will and
- the recent political history of the country, that was incapable of accepting
- any form of critisim, constructive or otherwise.
-
- After years of neglect and much abuse, the fate of the lake's biology is in
- a rather serious mess. Many of the fish which are native to it, have stopped
- spawning and their numbers are way down. The sediments particulary around the
- estuarys to some of the most polluted rivers are heavily contaiminated with
- heavy metals and organic toxic wastes - DDT and PCBs. Even though the mirco-
- biology of freshwater and marine systems do not often seem very exciting they
- are in fact cruical in every case, as much of the biomass is found there and
- it forms the base of the food chain. Further evidence of serious damage to the
- lake ecology, was the disasterous seal deaths that started in 1987. Thousands
- of seals have died and in a very similar manner to the castrophe that hit the
- North Sea in Europe in 1988. In both cases, the waters are badly polluted and
- it was suspected that the immune systems of the seals were (and still) are
- under severe stress from the buildup of toxins, pesticides and many other
- compounds in the food chain, and this stress made them highly vulernable to
- opertunistic infections.
-
- The latest threat now looming over the lake, is a massive increase in tourism
- and in addition the recent commencement of the transport of oil from one end of
- the lake to the other. Last year over 40,000 tonnes were transported. And with
- the type of weather encounted out on the lake, thick fogs, storms and hurricanes
- it is unrealistic to think that an accident is NOT going to happen. It is quite
- possible that one tanker load of oil could cover the entire lake in one giant
- sized slick.
-
- The only positive aspects to report are that the Soviets and particulary
- local environmental groups have been making some protests and some efforts have
- been taken to the address the problem. However the situation is largely hopeless
- given the massive burden of the environmentally crippling industrial
- infrastructure that straddles Lake Baikal. And finally last year a delegation
- from UNESCO, compared Baikal with the Galapagos, which is a World Heritage Site
- because of the large number of endemic species. But don't be fooled by this
- glimmer of hope because the omens are not good for this great Lake.

- 2) The Real Value of Biodiversity
-
- While there is much discussion these days about saving the rainforests and
- protecting their diversity, there is very little said about why it is all so
- worth while saving. The reasons for the lack of further discussion are numerous
- but the main one is that it is suspected that all the plants and creatures of
- the rainforest are vital to the well being of the BioSphere, and because so
- little is really known about what (still) exists in the rainforests, nobody can
- say for sure anything concrete about saving them, except that the approach
- should be one of caution.
-
- The situation is largely as follows: It is estimated that 90 percent of the
- species of all living things lie within a band roughly 15 degrees north and
- south of the equator. Up to about 15 years ago, it was thought most species
- were discovered, but now it is known that this is definitely NOT the case.
- Only about 2 million species have been classified so far since classifying
- began 200 years ago. However from the ratios of known to unknown species turning
- up in the rainforests it is estimated that the real number is somewhere between
- 20 and 30 Million species. The bulk of them are insects of course, and about
- a quarter of them are releated to Beetles. Back-boned animals make up just a
- few hundred thousand species. (It should be noted that since so little work has
- been done on marine animals such as worms and crustaceans that these have not
- even been brought into the equation correctly. It is thought that the coral
- reefs and deep ocean basins may be in many ways as diverse as the forests them-
- selves.) The current rate of loss of species, which naturally enough is occurr-
- ing in the forests may be at the level of 1.0 percent or more per year and
- increasing. What this means, is that at this rate within 60 - 80 years, up
- to 70 or so percent of all living things could easily have vainished from the
- Earth forever.
-
- The value that should be attributed to all this diversity is difficult to
- even define. We often here of the medical benefits mankind could reap, but
- while this is true, it is nothing in comparison to the great loss of pure
- knowledge, beauty and wonder of all these living things. It ought to be
- borne in mind that what really makes humans different to other animals is
- that we claim to find out about ourselves, our living environment and the
- rest of the physical universe. Thus it would seem to be a natural imperative
- that if we devoted our resources, we ideally should undertake to finish off
- the classification of all species and to protect and perserve them. The
- complete examination of all ecosystems should be undertaken and studied,
- from the ocean floors to the forest canopies. And while, being presently
- totally unrealistic, it is also imperative that the genetic genome of every
- plant, animal, insect, fungi and fish be mapped. The mapping of the human
- genome, which is the largest, is already under way, although the project was
- launched with not quite the same sort of ideal as above. It is only in this
- larger view of life, that one can appreciate what a great loss is occurring.
-
- On a more immediate and pratical side, the value of the rainforest lie in
- the number of useful and valueable fruits that could easily be gathered today
- from them. If people were allowed live within and thus off the forsest and to
- collect and sell some of the hundreds of fruits, nuts, roots, leaves, herbs,
- and many other crops from the forest, their value would by far exceed the
- present pitifull amount that is received for the same forest in the form of
- logs. A cleared forest is totally incaple of supporting any significant number
- of people. It is well known and documented how poor the soils generally are in
- most rainforests and the disasterous consequences of large scale clearing and
- burning. The local climate is invaribly affected too. Not only this but the
- forest is part and parcel of the cultures of any of the Indian tribes that
- still remain there, and they are nothing without the forest.
-
- Thus it is becoming clear that the biodiversity while having much value
- in terms of knowledge and beauty, also has economic value too. For all of the
- forest peoples of the world the biodiversity around them has shaped both their
- lives and their cultures.
-
- Viewing biodiversity from the dynamical side, their are similiarities with
- simple and complex ecosystems to simple and complex economies. For example,
- because the ecomony of say the U.S. or Europe have many components they are
- relatively stable to perturbing effects. This is ultimately related to the large
- number of positive and negative feedbacks. In an economy such as many Third
- World ones, where the export of bannas, sugar cane, coffee, or minerals may
- make up half the GNP, such an economy is considered far simpler, and is more
- likely to undergo wild fluctations, when perturbed. - i.e. world drop in the
- price of the commodity being exported. Therefore it must surely be evident
- that the multitude of bacteria, plants, fungi, insects, and animals (predators
- and prey), serve to have an overall stablizing effect on each other and their
- environment. Many field studies and (computer) simulations of populations of
- insects/animals have shown that under simple condtions are rules, and usually
- with no predators, the populations quite often vary widely, in boom and bust
- cycles, (like the simple economy above). In reality of course, there is usually
- more stability where predators, supply of food, competition, disease and other
- environmental factors are all interacting. (Naturally this is not always the
- case everytime, but it is still far more stable than a simpler 'model'). This
- stability is also reflected in terms of the uptake, release and availability of
- nutrients in the soil and water of any ecosystem. Even on a global scale it is
- recognised the biological impact that exists for the Carbon, Nitrogen and
- Sulphur Cycles. If no life existed on Earth, the levels of these chemicals and
- of probably all others as a result would be radically different. Nearly every
- other major chemical cycle known is effected by life on Earth. The details of
- these processes are very intricate and little understood, but if one considers
- for a moment that all plants, animals, algae, and bacteria are constantly
- absorbing and emitting numerous gases, from a multitude of biochemical
- activities, then it becomes apparent, that stability here is crucial. For
- example many of the gases present in the atmosphere in 'trace' quantities, such
- as methane, ethane, nitrous oxide carbon monoxide, sulphur dioxide, and
- literally thousands of others, including a host of complex organic molecules
- are the result of bacterial and fungal activity. However many of these same
- chemicals are important catalysts for many reactions, such as formation and
- destruction of ozone. They also react with the hydroxol molecule (OH), thus
- determining it's concentration in a given location. The hydroxol radical is
- formed by the dissociation of water (by sunlight) and in recent years, it has
- been realized that it is important in the breakdown of many other compounds in
- the atmosphere, and so is thought to be one of the mechanisms by which the
- atmosphere 'cleanses' itself.
-
- At this point, only a fool, would not recognise, that the real value of
- biodiversity is the health of the whole planet. Any threat to it, is a threat
- to the stability of this living system of which we are a part. It does not
- matter whether we understand or even know all the details and workings of
- the system, before we can decide to say that yes, it is wrong to damage it.
- It is plain obvious for all to see.
-
- Some people might suggest, that we can safely discard much of the
- biodiversity that exists, as there still would be enough diversity to give the
- BioSphere stability. To this I would say, the very suggestion, presupposes the
- person making the suggestion seems to know how it all works and is confident
- of his or her theory. All I can say is that such a scenario to me would seem
- like a gamble where you put all your life's saving and your house on the bet,
- and even if you do win, the prize will only be half of your original bet,
- because this is what such a suggestion makes - half the species. It would be
- very foolish indeed. In addition in the last few years, the upsurge in the
- study of chaos theory and it's associated branch of fractals; it has become
- patently clear how far more complex the world is and has demonstrated
- particulary how complex systems, which the BioSphere is, can be subject to
- castrophic effects and jumps to new states - or in mathematical terms shifting
- to new 'attractors'.
-
- To put the above discussion in some more light, it is should be clear,
- that the whole biosphere is presently under the influence of a major
- 'perturbation' and already many of it's internal systems and cycles have
- undergone radical alteration. These take the form of existing species loss,
- loss of predators in many populations, new environmental factors - such as
- pollution, and massive loss of habitat. The BioSphere is no longer operating
- under the conditions it did even 20 years ago, and cannot be expected to
- behave as it once did. Our only insurance in this whole biological system
- - it's biodiversity - is rapidly been taken away.

- 3) The Population Crisis.
-
- The population crisis has been away from the media for quite some time now,
- although the crisis itself has never left us. Most people are reasonably clear
- in their minds that the world's population will be a problem on us all, long
- before it gets to the stage of no standing room. The real issue of course is
- with the use and distribution of resources of all kinds. Ideally these would be
- used most efficiently and everyone would be friends, thus nobody would starve
- either. But this is not the case.
-
- Humans whether as individuals, as a mass, nation or culture, tend to act
- like animals. That is they look after themselves and forget about everyone else.
- And so we see this reflected in the world today. While places such as the Sudan
- Ethopia, Bangladesh starve to death, Europe, Japan, Austrialia and the U.S.A.
- stuff themselves silly, have problems with over-eating, and spend much of their
- spare money and time on leisure. Leisure meaning, sports, holidays, partying,
- drinking, Christmas time, films, video games and so on. All of this sulphurus
- activity also requires enormous amounts of resources, from minerals, to wood,
- paper, oil, to energy, on top of our already 'essential' needs. Clearly then
- there are some differences between the various groups on the planet.
-
- In this respect, the more affluent 1/4 of the population behaves towards
- the rest, in terms of aid and help in a similar vein. Because of this the
- population crisis is headed for a double blow. The first is the insufficient
- levels of aid and of that provided, quite often the irrelevence of much of
- it. The second blow comes from the fact that many of the goals set out in
- the early 70's by agencies (WHO, U.N.) and governments have failed totally to
- meet their targets, chief of which were to bring down the global birth rate.
- All the problems that were proclaimed that were going to be solved, were not.
- Also during the 80's for the first time since the colonial days more money
- flowed to the rich 'North' than aid going 'South'. This is as a result of
- the massive burden of debt repayments, of which after all these years of paying
- interest on the loans, few or none of the countries have managed to pay back a
- single penny/cent on the original amount. This loss of revenue to the host
- governments has meant that hospitals and schools haven't been built, running
- water and sewage systems not built and health and birth control programs not
- implemented.
-
- In fact during the 80's much of the funding for birth control, chiefly
- financed by the U.S. because it is such a large country, has been axed. Over
- 190 million dollars were cancelled. The prime movers behind this have been
- the anti-abortion lobby, who irrationally have taken their campaigns far
- beyond their own agendas. This loss of funding over the past decade may
- be the cause of up to 400 million extra births. The anti-abortion lobby have
- reasoned that this money was been used to encourge women to have abortions.
- In reality the effect has been totally disasterous, because many of these
- programs for family planning and birth control also had a educational and
- health component to them. If these people were so concerned why didn't they
- promote this money to raise the status of women in very large tracts of the
- Third World ?
-
- To throw some light on the situation in countries throughout Africa and
- Asia particulary, it is worth examining the plight of women. In the countries
- where the highest birth rates, and generally the gravest problems, women
- are treated as 3rd or even 4th class citzens. The system there is, that they are
- married over at an as early age as possible, 15 and younger. They have no say
- in the number of children, but normally they would have 10 or more. When
- it comes to meals and education, priority is always given to the sons, who
- receive their portions first and if any of the family is sent to school,
- usually it is the sons, first. Women do much of the work, and raising the
- family. Their daughters end up been raised in the very same social climate as
- they (their mother's) were in which they have very little say and unlikely to
- have any education, and therefore illiterate. This immediately makes it far more
- difficult for them to get information about health programs and other matters.
- Life for them is survial, a mere existence, not life as we in the rich 'North'
- know where we even have time to think beyond the next meal, because our
- stomachs are not paining us. To most of us, the extreme poverty of these people
- is unimagineable for us. However it is these very people that need to be helped.
- It is in the gettos where they live, where because life is so miserable, disease
- so prevelant, (generally from lack of sewage and water facilities), that they
- have more children; -precisely as a guarantee, that they will somehow help bring
- income to the family and thus help their parents. To understand why the
- situation is so; it is neccesary for us to visualize what it is like, and if
- need be then to see for ourselves. In the West, we often hear that if the
- relevant countries could raise employment and industrialize then these people
- would have income. What they fail to recognise is that in a true capitalist
- society, nobody would employ them anyhow. That's because they have received
- no education, may be chronically sick, and suffer from a number of disabilites
- because lack of nourishment while growing up. Furthermore the mental development
- may have been impaired again because of lack of sufficient food, while young
- and while they were still developing in the womb. The West seems to think
- that if they tell these countries to adopt what they do, the problems will
- somwhow go away. However they are not usually as forthcoming with the aid as
- they are with the advice. The tendency is for presititous mega-projects that
- benefit nobody, but harm everyone, while requests for running water at even a
- few locations are ignored, where in fact the amount of good and benefit they
- could bring is way beyond their proportion/size. This scenario repeated again
- and again all over the Third World, is the core of the population crisis.
-
- In countries throughout the Third World, in towns and villages where there
- are programs to involve the women in the decision making and to make them
- literate, in other words where the status and role of women has been RAISED,
- the birth rate has DECLINED. Raising the status of women has proved to be
- time and time again the one way to bring down the birth rate. It is precisely
- these and other sort of programs that the axing of funds, due largely to the
- anti-abortion lobby in the US, have cancelled. The effects of gentle persausion
- and better standard of living are far longer lasting than forced birth control
- which only causes resentment, and in the long run makes the problem worse.
-
- The population of the Earth has surpassed 5 billion and it well on the way
- to the 6th. The growth rate is explosive and in the current regime of things
- the use of resources by the rich and the laying waste of large parts of land
- due to massive urban and rural populations of the the remaining 3/4 will not
- be able to continue for much longer. There is simply no cooperation or help
- going on that is worth talking about. The West is more concerned with the lives
- of celebrities and fictional characters in soap operas, than the plight of
- the planet. It is not for a lack of brains or human ingenuity that the
- situation cannot be salvaged. In fact much of the technology, skill and
- finance is there. The will and perhaps the message is not. There are a million
- things which could be done. For example Kenya, in Africa has the highest birth
- rate in the world at approx 4 percent. The population is currently about 40
- million, and at this rate (~4%), it will double in 17 YEARS. If one considers
- for a moment, this means another 40 million is just one country, then it
- becomes clear, that not even the richest country in the West would be able
- to provide the same level of infrastructure, in terms of the number of schools
- hostipals, factories, food output, sewage treatement, running water etc that
- would be required to maintain it's standard of living. To help imagine this,
- consider the consequnce of the population of the US going from it's roughly
- 240 million to 480 million in 17 years! But like any other Third World country
- Kenya has to carry the burden of debt with it as well as it's existing problems.
- It is therefore plainly clear to everyone, that the Third World debt HAS to be
- canceled. The price of not doing this now, will is incaluable. This problem
- cannot be looked at in isolation -that is to say, the money was lent and there-
- fore it must be paid back. Besides it has got to be remembered that much of
- it was lent when interest rates were lower, and at the time the GNP growth
- rate in the Third World was relatively high. Banks simply assumed high growth
- and low interest rates. In fact the opposite occured. In many cases, in the
- mid to late 70's Banks were so eager to loan their money, that they sent out
- young men still in their early 20's around the world giving out loans to people
- like Marcos of the Philippines, (who promptly bought parts of Manhatten), the
- Miltary government of Brazil at the time. who poured more than $7billion alone
- into nuclear energy, with still little to show for it, even today. So an awful
- lot of the money lent never even went to their intended projects, and since
- most of the mega-projects were ill-conceived, there was no benefit. The only
- lasting result is that the West now keeps the screw turning on the Third World
- not by miltary colonialism, but by economic and financial colonialism today.
-
-
- Returning however to the main theme of this essay, the effect of population
- growth can be seen in other areas. For example, carbon dioxide (greenhouse gas),
- grew in emission amounts from 2349 million tonnes in 1950 to 6793 million
- tonnes in 1985. This represents a growth rate of 3.1 per cent a year. At the
- same time world population grew by 1.9 per cent and emissions per person rose
- by 1.2 per cent. We can see therefore that almost two thirds of the increase
- is accounted for by population growth. However it must be stressed that probably
- most of the growth per person occured in the West.
-
- Between 1971 to 1986, 125 million hectares of forest and woodlands were lost
- in developing countries according to the UN Food and Agriculture Organization,
- FAO. However in the same period urbanisation in these countries ate up more
- than 58 million hectares, much of it prime farmland. Thus half the land cleared
- was just used for making up the losses to cities and roads etc. This leaves
- about another 58 million hectares of new farmland. But much of this was
- marginal land, with poor soil and prone to erosion. So we can see virtually all
- of this expansion was at the expense of forests. Over this period (71 to 86),
- cropland grew by 0.51 per cent a year, and population by 2.2 per cent, (higher
- than 1950 to 1986). Consumption per person grew by 0.58 per cent, but technology
- change allowed a decrease of 2.3 per cent of cropland area per person. This
- means that population growth can account for four fifths of the growth in
- cropland, which from the above example, would also account for much of the
- deforestation in the world. However that are many regional effects suffering
- from their own problems.
-
- So it is clear then, that population growth coupled with poverty and
- excessive consumption by the elite 1/4 of the population is bringing to bear
- a large number of factors that are contriving to destroy much of the vitality
- and fertility of the Earth. It is worth noting too that perhaps all of the most
- fertile land, lying in river basins and deltas has already been brough into use
- or urbanised and therefore any new land be added to the world's stock of
- farmland is marginal at best. This is usually the sort of land where you only
- get one go if you are lucky to make it work, otherwise it is botched up on a
- permanent basis. So as the numbers go up, the pressures on the system are
- jacked up another few notches and like a ballon inflating, it will burst
- pretty soon, if the pressure is not backed off.

- 4) News
-
- * Seal Slaughter Update: As reported in the last issue, the fate of over
- 25,000 seals in the area of Port Nolloth off South Africa was at stake. At
- the last minute, efforts were made to prevent the slaughter. Unfortunately
- while media attention was focused here, a similar number of seals in another
- colony off the Namdian coastline, were later butchered and meat sent to the
- Far East to be sold as dog food.
-
- * Australia to ban mining in 'Australian' Antarctic: Australia is to bring
- in legislation to ban mining, oil drilling and prospecting both on land and
- off the continental shelf in those areas of the Antarctic, claimed by the
- Australians. Their move is part of the effort supported by New Zealand and
- France to prevent all mining activity there in the future, The present treaty
- of the Antarctic is up for renewal this year, which brings fears that this
- may herald the beginning of an 'assault' on the continent. Greenpeace and other
- environmental wish to make the Antarctic a World Park.
-
- * One small way to help save the Rainforests: Two American clothing companies,
- Patagonia Incorporated and Smith and Hawkin have agreed to buy a million buttons
- made from the Tagua nut, which grows on palm trees in the Ecuadorian rainforest
- in South America. They hope that people will choose to buy shirts and jackets,
- which use their buttons, over those which typically have plastic ones. The idea
- is that the rainforest will benefit, if their venture is successful, as local
- people, hopefully will then be able to receive a steadier income, from the
- produce of the forest, rather than the non sustainable source of income they
- have now, which is cutting down the forest and selling the logs in their own
- currencies, which are constantly being devalued.
-
- * USSR, Leningrad's drinking water: The city of Leningrad's drinking water,
- drawn from Lake Ladoga, is heavily polluted. There are 9 pulp and paper plants,
- two dairy complexes and a number of chemical factories along it's shore. It
- has also recently been revealed that a ship that sank there years ago, was
- carrying radioactive waste, and has been and is still leaking radioactive
- Caesium into the water.
-
- * USSR, Threat to Nuclear PlaLnt Safety: The continuing crisis in the USSR,
- is putting the safety of many of it's plant at serious peril. Staff moral at
- nuclear power stations is at an all time low, partly the result of protests
- and demonstrations outside the plants themselves. There has also be a drop
- in discipline, standards coupled with irresponsible management, antiquated
- equipment and outdated technology according to the Safety Commission chairman
- - Vadim Malyshev. This also has to be seen it the context of the potentially
- explosive situation in the outlying republics, where nationalist feelings
- have already reached boiling point. These factors increase, considerably the
- chances of another Chernobyl sized accident again.
- (NewScientist 11 Aug 1990, p 20, The European ?????? )
-
- * New system for classifying species: A new system of classification for
- living things has been suggested, which divides the tree of life up into
- three main classifications or kingdoms, instead of two as before. They are
- Bacteria, Archaea and Eucarya. Archea covers many algae, while the last kingdom,
- Eucarya, includes both plants and animals. However as expected they have many
- subgroups The new system is based around genetic considerations and is thus
- thought to be more fundamental.
- (NewScientist 11 Aug p 30 1990)
-
- * Fire threatens Golden Lion Tamarin Monkeys Habitat: A fire last February,
- in Brazil's Poco Das Antas Biological Reserve, has destroyed more of the
- remaining coastal forest habitat of the Golden Lion Tamrin Monekys. There is
- currently a program to try and save the remaining monkeys there from extinction.
- In the early 1980s there were less than 500 monekys, and since the habitat has
- been destroyed steadily since then, it is assumed the smaller areas left, can
- only support fewer and fewer animals. The conservation program, has already
- introduced 75 animals from zoos, (some of which had to be trained to peel
- bannas), to bosst the population. The program leader, Devra Kleiman of the
- National Zoo in Washington, D.C., has said that the fire, while not killing
- any animals, put the conservation effort back along way.
