So kiddo, the National Environmental Policy Act, or NEPA for short, is like a rulebook that helps people protect the environment when we do big things like build roads or power plants.
Just like how you make a list when you go to the store so you don't forget things, people who want to do big projects have to make a list too. The list is called an Environmental Impact Statement, or EIS for short. It helps them think about everything that might happen to the environment when they do their project.
When people are making their EIS, they have to think about things like if there are any animals living there, what plants are growing, if trees will be cut down, how much pollution might be made, and what people who live nearby might think about the project.
Once the people who want to do the project make their EIS list, they have to show it to the government to make sure that they’re not hurting the environment too much. The government looks at the list and decides if the project is okay or not. If it's not okay, they have to change the project so it’s better for the environment.
So, NEPA is like a helper that makes sure that we think about the environment when we do big things, and that we're doing our best to take care of nature so animals can stay in their homes and we can breathe clean air.
