I know this looks hopeless. But the entire humanity isn’t responsible for the mess the world is in. In fact, the vast majority of humans are innocent beings who don’t intend any harm on other humans or the nature.
It’s just a tiny percentage that’s the problem - an extremely greedy and sociopathic minority. Making the entire human race disappear is not going to work, since these vermin will find a way to sacrifice all the innocent ones, save themselves and take all the resources for themselves (exactly like in this news story). The only reason there is some sanity is because the good people fight back. And that’s the only option we have.
