Ecosystems are areas where things live. Ecosystems that are biodiverse are home to a variety of plants and animals. A healthy ecosystem is one with a lot of biodiversity. Imagine if humans could only eat one kind of food, say corn. Wed be in big trouble if all the corn disappeared. Besides not having anything to munch on at the movies, wed have nothing to eat at all. Luckily, our ecosystem covers a big part of the Earth, and there are lots of different plants to eat. Ecosystems are not as simple as one living thing eating another, as the corn example. The lives of animals and plants are intertwined - what happens to one animal can have an impact on all sorts of living things. As humans, we have a big effect on the other living things around us.

Its important for us to think about the choices we make and how they will affect the other living things around us. Remember: The Earth
