"Give me land, lots of land, under starry skies above. Don't fence me in." Have you ever heard that song? It describes a love for open spaces, mountains, and trees. Our land is an important natural resource.
Land provides a place for humans and animals to live. It also provides places to grow crops, trees, and grass. These are important resources for living things. What other natural resources do we get from the land? Let's start from the top.
At the surface of the land is topsoil. Topsoil contains minerals and nutrients that plants need to grow. Rich topsoil is used by farmers to produce food for us to eat. It can take up to 1,000 years to form a few inches of topsoil. But those few inches can be lost in a matter of minutes. Without plant cover, topsoil can be eroded by wind or water very quickly.
