Events roofed include the properties that DDT had on the
environment and the Cuyahoga river in Ohio catching fire because it was so
polluted.
In 1969, the crew of a Japanese fishing vessel near Bikini
Atoll were exposed to enormous doses of radiation from the outcome of an H-Bomb
test.
The anxiety over the environment went on way before that,
though. I think that it attracted people from other movements, like anti-nuke
and people concerned over industrial waste, etc., because the environment trapped
all of that under one umbrella that united them in a common cause. In short, it
was better to stand together than in smaller groups
hope it helps
