I was an elementary student [in 1970] and my school organized a great cleanup in Greenwich Village to commemorate the day. The city — which was particularly dirty, back then — was really buzzing with excitement. There was a general feeling of possibility and jubilation — and a realization that it was our responsibility to keep our planet healthy.

[In 1990] I was working for the National Audubon Society and already deeply involved in the environmental movement. We hosted a booth to engage and educate people in honor of Earth Day. I recall a lot of really positive energy and excitement — both at our booth and around the city.
