World Earth Day, celebrated on April 22 each year, is dedicated to raising awareness about environmental protection, conservation, and sustainability. With approximately 1 billion participants globally, the day encourages actions ranging from community clean-ups to protests aimed at combating climate change. The 2026 theme, 'Our Power, Our Planet,' highlights the importance of human agency and collective action in addressing environmental challenges. Earth Day originated in 1970 in the United States, sparked by widespread protests against industrial pollution, leading to the establishment of the Environmental Protection Agency and key environmental laws. Since its global expansion in 1990, Earth Day has become a pivotal platform for mobilizing action against climate change, emphasizing the interconnectedness of ecosystems and human health. As global temperatures continue to rise, the significance of Earth Day grows, with a focus on preserving biodiversity and promoting sustainable practices.
