Okay, kiddo, let's talk about protected areas in Sierra Nevada. Imagine a big, beautiful forest with lots of trees that provide shade and fresh, clean air. This is Sierra Nevada, a mountain range in California. However, some parts of the forest are in danger because people build houses, chop trees or leave trash behind. That's why a group of adults decided to create protected areas in Sierra Nevada. Protected areas are places where nature is looked after and no one is allowed to do anything harmful to it. It's like a secret hideout where nature can thrive without any danger. These areas are monitored by park rangers who make sure that animals and plants in the forest are taken care of, no one is littering, and everyone follows the rules. In fact, people can go and visit these protected areas, but they must be very careful not to disturb the wildlife or nature. So, in Sierra Nevada, there are special places where nature is kept safe and healthy, and you can visit them if you promise to take good care of it too.
