Earth Day, also known as International Mother Earth Day, is celebrated annually on April 22 to promote awareness about the importance of protecting our planet. The observance began in 1970, inspired by Rachel Carson’s influential book 'Silent Spring', which raised public concern over environmental degradation. Senator Gaylord Nelson organized the first Earth Day event after witnessing the effects of an oil spill, leading to over 20 million Americans participating in protests for cleaner air and water.

The theme for 2026 is 'Our Power, Our Planet', which underscores the vital role individuals and communities play in combating climate change. It calls for a shift towards renewable energy and sustainable practices. In light of pressing issues such as resource depletion and biodiversity loss, Earth Day serves as a reminder that every action counts.

Individuals can contribute to environmental efforts by adopting practices like reducing waste, planting trees, and supporting renewable energy initiatives. Other ways to make a difference include participating in clean-up activities, advocating for sustainable policies, and choosing eco-friendly products. By taking these steps, everyone can play a part in fostering a healthier planet for future generations.
