Earth and mankind
Saw an interesting quote the other day:
The Earth doesn't belong to man. it's man who belongs to Earth.
Sorry, but Mars is a much more dangerous place to live than Earth.
MGS spotted 20 impacts in 6 years on Mars. I'm not aware of anything like that on Earth. Mars has a much thinner atmosphere and is closer to the asteroid belt.
It's simply impossible to move enough humans to Mars to use the "survival" argument.
And besides, isn't it elitist? That won't pass well among the population.
We must take care of our planet, planet Earth.
