Protect Solar System From Mining 'Gold Rush', Say Scientists (theguardian.com) 229

An anonymous reader quotes the Guardian: Great swathes of the solar system should be preserved as official "space wilderness" to protect planets, moons and other heavenly bodies from rampant mining and other forms of industrial exploitation, scientists say. The proposal calls for more than 85% of the solar system to be placed off-limits to human development, leaving little more than an eighth for space firms to mine for precious metals, minerals and other valuable materials.

While the limit would protect pristine worlds from the worst excesses of human activity, its primary goal is to ensure that humanity avoids a catastrophic future in which all of the resources within its reach are permanently used up. "If we don't think about this now, we will go ahead as we always have, and in a few hundred years we will face an extreme crisis, much worse than we have on Earth now," said Martin Elvis, a senior astrophysicist at the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts. "Once you've exploited the solar system, there's nowhere left to go..."

Working with Tony Milligan, a philosopher at King's College London, Elvis analysed how soon humans might use up the solar system's most accessible resources should space mining take off. They found that an annual growth rate of 3.5% would use up an eighth of the solar system's realistic resources in 400 years. At that point, humanity would have only 60 years to apply the brakes and avoid exhausting the supply completely.

      Even if we were talking PURE GOLD, on the surface of the moon for the taking, we wouldn't come close to breaking even.

      • You don't bring the raw materials to earth. You mine in space, you process ores in space, you make the metal and manufacture goods in space. Nearly all of which gets used in space. May some of these goods get sent to earth. At most, finished goods or high end industrial materials like steel i-beams or plates. *IFF* they have some property due to low G manufacture that we can't replicate by recycling steel that is already here on earth.

            Only if you only use your reusable rockets once.

            If a reusable rocket costs twice as much as a non-reusable rocket (per kg launched), then it works out to be more cost-effective with three or more uses per.

            And based on SpaceX costs, reusable rockets are, at most, slightly more expensive than non-reusable rockets. So you come out ahead on the second use....

If the moon was gold, it'd be about break-even at this point, but you could bet your last dollar someone would figure out how to get it back for cheap...

      And declare chunks of the Earth as a nature preserve.

    • Two different skill sets. There's little to gain by poking holes in our living quarters. We've always gathered resources on the surface like stones and sticks, or just subsurface like ores and a little deeper for oil and water.

      It's much easier to mine surfaces than dig holes. Solar objects have plenty of surface area.

      That's our next pollution stop. We already have garbage on the Moon and Mars, right?

    Antarctica is still just a remote base, because exploitation has been prohibited by treaty.

    An intelligent approach would be to consider the kind of governance that would prevent companies from being reckless.

    Not everyone feels that asteroids are there for their own sake, and that no rock may be turned over. Indeed, if we felt that the Earth and solar system should remain as they are, then we humans would have to exterminate ourselves, in order to avoid any human footprint.

    • Antarctica is still just a remote base, because exploitation has been prohibited by treaty.

      The reverse is the case. The minor prospects for profitable exploitation made it relatively easy to create a protection treaty. No one forced any nation to join the treaty, and it only binds the nations that chose to join it - currently 54 out of about 200 nations on Earth. Even signatories could withdraw and begin exploitation of some kind (what?) if they chose to do so.

        We can't make more land

        Why not? Build a big enough habitat (say, a ring 1000km in diameter, 10km wide - which is 3,000,000 hectares of new land) using nickel-iron asteroids as the base material, and we have more land. Do it 1,000,000 times, and we have multiple worlds worth of new land. Soon? Not hardly. But certainly not impossible...

        • The problem is an atmosphere, gravity, enough light for growing plants, etc. We're quite suited to living on Earth, building an Earth-like habitat would most likely be orders of magnitude more expensive than simply figuring out how to mine the other celestial bodies and shipping the output back to the Earth.

I don't care whether anyone adopts this or not as even at 10% of the solar system we could not even dream of that sort of impact for thousands of years and I would hope by then we are not so destructive that this matters.

Your reasonable growth rate of 3.5% would mean human population in the thousands of trillions and it is 350% higher than our current growth rate (which is decreasing and expected to move towards 0.5% within 30 years). For this to be even the remotest of concerns we would actually have to hit that 1,000 trillion population mark and have made no discoveries to better mankinds consumption in that time.
