On April 22nd 1970, 20 million Americans took to the streets, parks and auditoriums to demonstrate for a healthy, sustainable environment in massive coast-to-coast rallies. Spearhead by Senator Nelson, after witnessing the ravages of the 1969 Santa Barbara oil spill, the first Earth Day protests forced environmental protection onto the national political agenda and led to the creation of the United States Environmental Protection Agency and the passing of key environmental legislation.
Today, Earth Day is widely recognised as the largest secular observance in the world, marked by more than a billion people every year as a day of action to change human behaviour and provoke policy changes. Now, the fight for a clean environment continues with increasing urgency, as the devastating effects of climate change become more and more apparent every day.
To mark Earth Day 2021, Elsevier presents a curated list of free access journal articles and book chapters in support of this year's theme - Restore our Earth.
