Do you think humans should try to set ups colony on mars? why or why not?

The reason why is because of a the population on Earth. If we can find a way to make Mars a suitable place for humans and even animals to live, we can drop the population on Earth so we don't use as many resources, and the Earth can last longer. There would also be less pollution, toxic waste, etc.. This is why I think we should try to set up colonies on Mars or other planets :)

I don't think they should because of no gravity... Its also very dangerous.

Based off the appearance of the peppered moth, its markings would not be advantageous in a lush green ecosystem . this could cause their population to decrease as the camouflage factor would be somewhat useless and make them much more vulnerable to predators .hope this : )
