Environmental groups are organizations that focus on protecting the natural environment and promoting sustainable practices. They work on various issues, including climate change, wildlife conservation, and pollution reduction. These groups often engage in advocacy, education, and community outreach to raise awareness about environmental challenges and solutions. Many environmental groups also participate in policy-making by lobbying governments to implement laws that protect the environment. They may collaborate with other organizations, businesses, and communities to promote initiatives like recycling, renewable energy, and habitat restoration. Notable examples of such groups include the Sierra Club and Greenpeace.
