What does better world even mean? We exploit and fit the world and others to our needs - it will stop only if we all die.

And how can you even say that world is getting worse or better? In the end, your perception of "state of the world" is just a feeling. You don't have enough information to give somewhat objective score. You will never have. The world is too big with too much of moving parts for you to make an accurate forecast.

My suggestion: be simple, solve problems, enjoy what you have, don't get fanatical (or you will ruin my day someday).

P.s. what I can say is that all problems we have right now are product of other humans and our deals with them. Examples: you need to work 8 hours every work day even though humanity produces much more food than everyone really needs, we can create home (comfortablr and with basic needs) for everyone with machines and resources we have already, we can provide medicine and heal every illed person. Including prevention of horrible genetic mutations in early child development for every such child. Nature does not stop us anymore. We just can't figure out how to manage and control ourselves.
