Since 1970, citizens from around the world have joined together to celebrate Earth Day on April 22. While the specific goals of each annual Earth Day observation change from year to year, the main purpose of this event is to bring attention to the need to protect our natural resources and the environment around us. As a designated World Health Organization Centre for Food Safety, Water Safety, and Indoor Environment, NSF is pleased to continue its involvement by providing the following educational materials.
