Earth Day was first held in 1970 to show support for environmental protection. It came after a massive oil spill in California in 1969. The Earth Day Network works towards changing things for the better when it comes to: Climate Action, Science and Education, People and Communities, Conservation and Restoration and Plastic and Pollution. Earth Day 2024 is committed to reducing plastic and is demanding a 60% reduction in the production of all plastics by 2040.
