https://padlet.com/nhsu25/kqi7ja3jcl5uqq7s The modern environmental movement, which first took shape in the 1960s, hit its peak in the 70s, but held its momentum through the 21st century, has never been linear. The movement to bring awareness to humans’ detriment to the planet has been through many realizations, protests, campaigns, triumphs, and setbacks – and although this timeline only captures a sliver of the movement, please keep in mind that activism and action continued far past the last date you see here. en-us 2023-05-12 19:04:42 UTC 2025-11-02 02:24:56 UTC hello@padlet.com nhsu25 https://padlet.com/nhsu25/kqi7ja3jcl5uqq7s/wish/2589795983 1948: In Donora, PA, 20 people die and over 600 go to the hospital from sulfur dioxide emissions from a nearby steel and wire plant.
