I agree that there is a possibility of having other planets that can sustain life as Earth is able to. However, none have been discovered and even if so, it would be millions of lightyears away and we don't have the technology to travel that far. However, if somehow we did have the ability to travel that far and onto a habited, civilized planet, we still can't just take it away from its original inhabitants. Therefore, i agree with the picture that this is the only habitable planet we get and we should treasure it. (Just my thoughts honestly, not flaming anyone)
