We hear a lot of Climate change, climate emergency, so on and so forth.

The "experts" are hard at work determining the best Policy to save humankind. They meet in big international climate change conferences like recently held COP28 in Dubai. 

But the answer is actually very obvious. Somehow no "experts" want to acknowledge it.

The best way to save the environment is to actually increase the Wealth of the people. Cause once you are wealthy, you start to focus more on cleaner environment. 

Have you notice rich neighbourhoods are generally cleaner?

If you are poor, you have many other things to worry about apart from the environment. Poor people may also have no or little other choices apart from continuing environmentally destructive practices.
