This has always been a major problem. And probably will so continue.

Can we develop renewables and fossil fuels in a sustainable way?
I doubt it.
Our atmosphere consists of a thin skin of gas around the world.
We cannot replace it.
If we pollute it beyond a certain point, it becomes unusable, and we die.
So we need to rein in any excessive use of materials on our planet.
Which means we need to live a simpler life.
I doubt that will happen too.
So we are headed for some kind of climax or disaster along the road ahead of us.
Future generations are not going to thank us methinks.
And a word about poverty.
Our particular ancestors were innovative.
I think they had to be because they lived in cold climes.
They had to think hard or perish.
They thought hard.
So they survived well.
And advanced us swiftly to the level of comfort we enjoy today.
In places where people didn't need to think so hard to survive, standards remained basic.
So much so, that by comparison, they are now far behind us.
I think we should be willing to show them how to improve, but not try to live their lives for them.
It is up to them to get organised, and bring their own standards up.
If they can't or won't do this, their standards will remain low.
We must accept this reality
