Founded in 1970 by US Senator Gaylord Nelson, Earth Day is observed by 190 nations worldwide. This year’s theme is Our Power, Our Planet. 

Earth Day offers an opportunity to take collective and individual action: to protect the environment, to mitigate climate change, and to promote sustainable practices. Whether it is planting trees, making sustainable fashion choices, reducing plastic consumption, participating in advocacy, cleaning beaches, or donating, every action counts.
