Environmentalism is a social and political movement focused on protecting the natural environment from harm caused by human activities. It advocates for sustainable practices that preserve ecosystems, reduce pollution, and combat climate change. Environmentalists work to raise awareness about issues like deforestation, loss of biodiversity, and the impact of fossil fuels on the planet. The movement encompasses various approaches, including conservation efforts, renewable energy initiatives, and policies aimed at reducing waste. Organizations such as the World Wildlife Fund and Greenpeace play significant roles in promoting environmental awareness and influencing legislation to safeguard the environment for future generations.
