Rewilding Britain is when people try to help the plants and animals that live in the wild be healthier and happier. It is like helping your friend get better when he or she is sick. People who do this try to make lots of natural habitats that are good for plants and animals to live in. This helps the animals and plants have enough food, shelter, and space to live good lives. It also helps make sure that some plants and animals that used to live in Britain a long time ago can come back and live there again.
People who help rewild Britain want to make sure that there are lots of different plants and animals living in the wild. That way, the ecosystem (which is like a big circle of life) can stay healthy and happy. Rewilding Britain also helps things like rivers and forests become cleaner and more beautiful. It's like taking care of a garden, but the garden is really, really big and it has lots of animals and plants living in it.
Overall, rewilding Britain is about making sure that the wild places in Britain are healthy and happy, and that the animals and plants living there have everything they need to survive and thrive.
