Upcoming Earth Day dates
Why Earth Day is on April 22
Earth Day, April 22, began in 1970 as a US environmental teach-in organised by Senator Gaylord Nelson after a major oil spill off Santa Barbara. Twenty million Americans took part, and the first Earth Day is credited with building the political support behind the Clean Air Act and the creation of the Environmental Protection Agency. It went global in 1990 and now runs in nearly 200 countries.
Planning ahead
Schools and workplaces tend to organise around a single visible activity — a clean-up, a tree planting, a repair café. If you are planning one, the ones that persist past the day are those tied to something ongoing: a recurring cleanup roster, a switch in procurement, a commute change.
