Earth Day is celebrated annually on April 22nd to promote environmental protection. The first Earth Day in 1970 involved massive rallies and events across the United States. Some ways to celebrate Earth Day include planting trees, making nature crafts, singing earth songs, and holding fairs to teach others about the environment. Environment Day is a UN initiative to raise global awareness of environmental issues and encourage political action and partnerships to address problems like pollution, waste, and energy conservation. Reducing, reusing, and recycling are important strategies to help solve waste problems and make more sustainable use of resources.
