Yes I have and also as long ago. But the overall message did burn into me. That is the environment is scared and we really should take better care of it.

Eg. Florida Everglades. In short 'in the name of progress' thought it was a great idea to redirect the water flow even when presented with much scientific data that this would be a bad thing to do. And it proved disastrous. Now the state is still trying to restore it.
