What do you think about earth

 Where should I start I don't know life and the world is so complicated that it is very difficult to talk about it, nothing you can say with certainty, the very next moment it is a changed race, the world I live in today  I'm so worried about him maybe my worries are in vain are we really totally honest about this earth are we trying our best to make the world better i feel like we're not doing it maybe  I may be delusional, but whenever I look at the ground reality, my illusion feels true. How many governments are there on this earth, how many powers, how many resources are there, but why can't I see anything changing, I feel as if the earth has become a swamp  And the whole human society is getting into it, I am worried about the rapid change that is happening, what should I do, I hope that I will do well, but whose responsibility is it to keep my hope alive?
