Plots for the Planet

I've been thinking about this for a while.
Some people have a lot of good story ideas. Characters, finales, scenes. But not necessarily plots. And finding an interesting plot that hasn't been done to death can be hard.
And as I'm sure you know, I'm into protecting the environment.
Combining the two is an excellent idea. Why not make your plot environmental?
There's a lot of great environmental movies/stories out there. The Lorax, Princess Mononoke, Fern Gully, Avatar, Nausicaa, and so on.
But what do all of these have in common?
They all focus on the same problem.
Cutting down trees.
Which is a problem. And one that most people agree is bad.
And while plenty of amazing things have come from this plot, it's one of the most simple topics. There are so many more you could use. And in the right hands, you could do fascinating stuff with these too.
the thing about them is they are often very controversial. Which is a great thing for stories. You can have people on both sides, with valid arguments and motivations to throw at each other.
Blending it with sci-fi and fantasy aspects can make it even more awesome.
What I'll be doing for a while is going through a list I've made of the big environmental problems we face. I'll write a post about each one, why it's a problem, what you can possibly do with it, where it may have been used before, and possibly some sources where you can learn about it. And I'll link to each of those posts here so they're all easily accessible.
