I conclude that I don't know the answer to this, and that you can't possibly know either :) At least to the extent of deciding to hypothetically committ genocide on hypothetical Mars life. (It'll solve many problems if there is no life on Mars). I don't pretend to know how much more human/bunnyrabbit/ fungus life is worth compared to the existance of Marslife. I do however know that _I_ personally get some joy in, for example, being in a woods with no beer cans. I don't know how to measure how much joy I will get from knowing that Mars life is living out its existance like it used to, but I know it will be non zero. Thus, I choose to wait and see what the circumstances are before I decide. >The only way you can logically make the situation on Mars the same as on >Earth is to a) Demonstrate that life there affects life here, or >b) Assert that life-in-general has value without Human life.

Any land made arable in a colder climate by global warming will be paid for with coastal flooding or inland desertification.

It would please me to know, since we are in high solar activity, that the ozone layers are dramatically affected by said activity. However, the effect of CFC's is real and should not be ignored. It is folly to continue to do something damaging to the ozone simply because we have not concluded what the extent of the damage can be attributed to our actions. >>>I didn't know we had gone to world goverment.

However, I would like to know how Mr Mohney thinks the UN gets its money. Also, instead of letting the quibbling about "taxing" get out of hand, I point out that Dave Knapp meant "tax resources" in the same sense that a difficult orbital mechanics problem might tax your analytic abilities. >>When the global population saturates, you will not be thinking 'piss ant' >>wars anymore.

Space...the final frontier. For the first time, the human race has nowhere to expand. As population goes up, the amount of arable land goes down. The only solution to this in the past has been to expand into the frontier. But now only governments and rich companies have access to the frontier, which is space. And population in undeveloped countries is increasing exponentially. >>>We've been running out of fossil fuels for 100 years. Before that, there was >>>a fear of a great shortage of whale oil, due to overhunting. >>No, we will *run out* of fossil fuels in less than fifty years. Um. Maybe oil. Not coal. Of course, accessing coal will reduce the amount of available arable land, and also contribute greatly to pollution and global warming; but nevertheless it is the cheapest way to go. I personally would like to see solar powersats in place; astronomers notwithstanding. But the human race is lazy and will take the easiest stopgap solution first. To rephrase; the market will not support powersat development on an operational scale until other alternatives with shorter lead times and cheaper development costs are exhausted first. >>>Could you tell me what the current demand for whale oil is? >>Ah, you're right.

Please take a look at it. Granted, but before you can launch a Zubrin mission, which _requires_ native propellants, we have to know that they work. I'd rather not wait till we've built Zubrin's hardware to find that out, but I also don't want to wait 15 years and find out by having an astronaut standing next to it. The bright side of this is that Shimizu (sp?) in partnership with an American firm is planning to fly some test equipment on a lunar lander some time in the mid-term.

In other words, who allocates the funding for planetary science data archives, or don't they do it in an organized manner, as ADP does? (ADP uses NSSDC resources all the time; I've telnetted McCook & Sion's white dwarf catalog from them, myself.)

Maybe I've just answered my own question, then, but you'd think planetary science would have its own dedicated program for archival research.

According to what I've seen in various articles and advertisments, CD "record" companies that re-issue old rock oldies on CDs from the orginal master tapes sometime run into these problems trying to play tapes in bad condition. Heard that they "bake" some tapes to get them to not fall apart upon playback. And other tricks. It might be possible to ask the people at one of these record companies for advice on reading the poor condition space tapes.

First, I'd like to point out that I'm not the same person who wrote the follow up to my post, nor do we agree on all things. Doug lumps us togther. Since the mid 80's, America has stopped giving moneyt to the UN agency that works to combat population growth in the third world. Come to think of it, I believe we don't give the UN any money anymore. Anyway, my point is the following, given that there is an unfulfilled demand for birth control (I don't think I've cited sources here, but if you want I'll dig some up) and that population growth in the third world tends to eat up progress made by foreign aid, it makes sense to help reduce growth - where the assistance is desired - instead of sending cash. I then went on to suggest that lowering growth would be more likely to help stabilize the region that not lowering growth.
