Earth Day, celebrated on April 22 each year, was first observed in 1970 and is a global event dedicated to raising awareness about environmental issues and promoting sustainability. Its origins can be traced back to the environmental movement of the 1960s, when activists sought to address pollution, deforestation, and the detrimental effects of industrialization. The date was chosen to coincide with spring, symbolizing renewal and growth. Over the years, Earth Day has evolved into a worldwide event, with activities such as tree planting, clean-up campaigns, and educational programs. It serves as a reminder of our responsibility to protect the planet and encourages individuals and communities to take action towards a more sustainable future. Furthermore, Earth Day events often highlight the importance of climate change and biodiversity, emphasizing the interconnectedness of all living things.<|im_end|>
