Environmentalists are individuals or groups who actively work to protect the natural environment. They focus on issues such as pollution, climate change, and the conservation of wildlife and natural resources. Their efforts often include raising awareness, advocating for sustainable practices, and promoting policies that benefit the planet. Many environmentalists engage in activities like organizing clean-up events, supporting renewable energy initiatives, and educating the public about the importance of biodiversity. They may also collaborate with organizations like Greenpeace or The Sierra Club to amplify their impact and reach a broader audience in their mission to safeguard the environment.
