Well, is the life the way we know it really the only one of its kind?-If yes, then we have to protect it and by doing so, we should probably protect our earth too.
I mean, think about it, if our Planet overheats, and isn’t able to protect us with a healthy atmosphere, we just die, the human race kills itself.-Wouldn’t that be sad and boring, it should be more like, “the human race saves itself by finding a way to get energy without stealing earth‘s fossil fuels and using them for themselves”.
If it’s not, then maybe we can find a civilisation, that will help us to find a way to keep living the way we do today, but so, that it’s good for our environment.
