  • While I would very much like to save the environment on Earth, people are not going to stop consuming the planet’s resources and allow that to happen. Equally as important, we don’t know how to save our environment. Do you know how to terraform the Sahara? I don’t. In fact, there are dozens of scientists with dozens of different ideas of things we can try that could help mitigate global warming and help restore natural environments. But doing so would amount to performing experiments on the Earth’s biosphere and we only have one biosphere to work with. If the experiments goes wrong, which any researcher can tell you is very likely, then we could do even more damage and maybe have no biosphere left at all.

    A better plan is to go someplace like Mars and experiment there. Learn how to create and manipulate a biosphere someplace where a failed experiment won’t potentially wreck the biosphere we need live in.

    Edit to add: Do you really want to let the Elon Musks of the world spread reflective dust in the ionosphere, or launch a giant sun-shade into orbit to block some of the sun’s light from hitting the planet? Wouldn’t it be better to do the experiments somewhere else?
