If people in, say, Uganda want to use DDT or build a coal power plant, what's stopping them other than the fact that maybe western governments won't give them money for it?

I'm just trying to understand this because other than these governments not having enough money, I don't know of any reason why they couldn't just say the heck with naysayers and build it anyway. Is there some other reason?
