Have you ever heard of the Peppered Moth? It's a great example of how living things can change because their environment has changed. And it's not just them! There used to be giant insects roaming the world, but they got smaller through time.
What do beavers, termites, and prairie dogs have in common? They all change their environments! Last time we talked about how humans change their environments, but humans are animals and all animals change their environments just by living in them.
Did you know that all living things change their environments? It's true. Beavers, deer, worms, and humans all change their environments. It just so happens that humans change our environments in big, obvious ways.
