William J. Sutherland is a person who is really good at understanding the relationships between different things in nature, like animals and plants.
Think about how you have friends and family members who are all different and have different needs. In nature, it’s the same way! Different animals and plants all have different needs and jobs in their ecosystems.
But what happens when one type of animal or plant disappears or gets hurt? This can cause big problems in the ecosystem. For example, if all the bees disappeared, we wouldn’t have as many flowers, and that would make it harder for other animals that rely on those flowers to survive.
William J. Sutherland studies these kinds of relationships between different things in nature, and he helps us understand how we can protect them.
He's kind of like a detective, but instead of solving mysteries, he is trying to figure out how to keep things in nature safe and happy.
