Do humans have the right to colonize other planets, such as Mars? What challenges will humans have colonizing Mars?

If you take a look at evolution on Earth, 99.9 percent of all life forms have gone extinct. When things change, either you adapt or die. That’s the law of Mother Nature. We face various hazards. First of all, we have self-inflicted problems like global warming, nuclear proliferation and bio-engineered germ warfare. Plus, Mother Nature has hurled at the Earth a number of extinction cycles. The dinosaurs, for example, didn’t have a space program. And that’s why the dinosaurs are not here today.

So i thiink the answer is yes?

not sure if this what   you'r looking for would be percent composition
