You certainly implied it with your post. 90% of what's happening to cause habitat to disappear or degrade, oceanic pollution, deforestation, and related issues can be traced back to the Third World.
For example, in Brazil it isn't some mining company responsibly operating a mine on say 10,000 acres of land for 50 years, it's the poor doing slash and burn agriculture and illegal logging that are gobbling up the Amazon basin and deforesting it. Places like Madagascar have been denuded of forest for the wood to cook and heat with. Oil and coal, like it or not, saved millions of trees from becoming firewood.
Moving to plastics, metals, and composite materials has saved us from using far more natural resources in wood and produced through costly agriculture.
It is the Third World, living in destitute poverty that's the problem, and money alone won't fix that.
