Environmental movements are organized efforts by individuals and groups to protect the natural environment and promote sustainable practices. These movements often focus on issues such as pollution, climate change, deforestation, and biodiversity loss. They aim to raise awareness, influence policy, and encourage community action to create a healthier planet. Throughout history, various organizations and activists, such as Greenpeace and the Sierra Club, have played significant roles in advocating for environmental protection. These movements can take many forms, including protests, educational campaigns, and lobbying for legislation that supports conservation and renewable energy initiatives.
