Earth Day: "Once upon a time in the US..."

[hootinholler]

1. It was also a time when the damage to the environment was obvious

I doubt there was anyone in the US who couldn't travel a short distance and see the devastation in an obvious way, like sulfur creeks or other dumps.

DDT had recently been identified as the cause of the decline and endangerment of the Bald Eagle.

These things are not so obvious anymore. Pollutants are no longer clouding our water and our air, but they are still there and are still big problems.
