In biology and ecology the environment is all of the natural materials and living things on the Earth. This is also called the natural environment. Some people call themselves environmentalists. These people think that harmony with the environment is important. They think we must protect the environment. The important things in the environment that we value are called natural resources. For example fish, sunlight, and forests. These are renewable natural resources because they grow naturally when we use them. Non-renewable natural resources are important things in the environment that do not come back naturally. For example coal and natural gas.
