Chicago Wilderness is like a big park in and around the city of Chicago where animals and plants can live and grow. It's like a giant playground for nature!
Imagine that you are playing in a sandbox with lots of toys, but instead of toys, there are trees, flowers, birds, and other animals. That's kind of what Chicago Wilderness is like - a big, natural playground for all kinds of living things.
But it's not just one big park; it's a bunch of different little parks and natural areas all connected together. This means that animals can travel from one area to another and plants can spread their seeds and grow in lots of different places.
People who live in and around Chicago can visit these parks, hike on trails, and learn about the plants and animals that live there. Sometimes people help take care of these natural areas by picking up litter or planting new trees.
All in all, Chicago Wilderness is a special place where people and nature can live and play together.
