An out-of-sight, out-of-mind approach to pollution would ignore the much more severe climate crisis we face 42 years after the first Earth Day and the EPA's creation. The Earth that everyone wanted to protect in 1970 has already become Eaarth, a different planet, with carbon levels having climbed to 392 ppm, 42 ppm above what climate scientists calculate is the maximum we can tolerate. Just as it took glaring pollution to create Earth Day, now a Yale study shows the growing number of people in the U.S. who recognize the link between weird weather and climate change.
