The Environmental Defense Fund (EDF) is like a big group of people who work together to help protect the environment. They want to make sure that the Earth stays healthy and safe for all living things to live on.
Think of it like a superhero team, but instead of fighting bad guys, they fight pollution, climate change, and other things that can harm the planet.
EDF has scientists, lawyers, and other experts who work together to find ways to make the environment better. They study things like how pollution affects the air and water, and they come up with ideas to reduce it.
They also work with businesses and governments to make changes that benefit the environment. For example, they might work with a company to figure out ways to use less energy or produce less waste, which can help the environment and also save the company money.
Overall, the Environmental Defense Fund is like a big group of people who want to protect the planet and make it a better place for everyone and everything to live.
