Terraforming Mars, or maybe just create a habitable satellite is easier than saving the earth. Current economical model fosters growing business, and only government regulation to deal with externality. Growing is intuitive to human activity, but restricting human growth is counter-intuitive.
I forget the link, but a lecture video using bacteria growth as a metaphor of human growth creeps me out. Supposed bacteria in a jar growth 2 times for 1 minutes, and the jar will be full in 1 hour. When will the jar be half full? Answer is at 59 minutes. At the time of 58 minutes, only 25% space is used. How many bacteria thinks the jar or the world will be full after 2 minutes?
The situation is similar to human, and we still cannot find a way to protect the environment and have economic growth at the same time. Maybe the end of human history is next 2 years but we still think its pretty okay and didn't notice anything unusual. Then maybe finding a new jar is the second best way to deal with it.
Holy guacamole. "easier to terraform mars or create a habitable satellite than saving earth"
this is the most ignorant thing I've ever seen written on the internet. Get back to me once you have 1/10000000th the bio-diversity of earth on your habitable satellite.
1) change our paradigms, economic system, and other social factors. I can assure you that this is far more maleable than Martian soil composition...
our social structures evolved in the context of low population densities and plentiful resources.
our economic system is what needs to give, it doesn't even function for humans, let alone the planet and the rest of life we share it with...
need I remind you that
1) we are only ONE species, and haven't the RIGHT to destroy our shared home, nor the other species. Some of us humans are upset about this, and we WILL take you other humans on over this issue!
2) our planet is STILL the only known place with LIFE in the entire universe. This is likely to change, at some point, but not if you get us all killed first.
3) our social systems are flexible, arbitrary, dare I say "PRETEND"... change em.
I propose a voluntary mission where all those interested in perpetual crapitalism and archaic social values voluntarily move en-masse to Mars, and please try not to rob too many of Earths resources getting there...
Bring the right wingers and life-haters with you too please...
bacteria in a jar grow and populate uniformly. Humans don't and tend to clump up in high population areas. Human population growth also tend to slow down with economical stability which is the opposite to bacterial growth.
As for mars, what we really need is to build technology that can make inhospitable places livable without infusing additional resources. A key point is water extraction, which would make a lot of desert environments much more hospitable with the right technology.
