A good point to be made here is generally speaking the plot involved one of the various villians INTENDING to go OUT OF THEIR WAY to pollute the world.
That wasn't grounded in reality or believable (unless you're super green hippie). It wasn't like they were scheming in destroyed the environment out of neglect like many corporations have been known to. The plot was "How can we make money AND destroy the ecosystem".
It was really too thick >.>
On another note, I still find it hard to believe LeVar Burton and Whoppie Goldberg were voices in that show.
