Natural Resources

Natural resources are the animals, plants and natural features of the Earth which humans use to support their lives and their needs. The natural resources of the world include the forests, which provide us with wood, and animal life, such as fish, which we take from the sea. There is a great danger that we are using up these natural resources too quickly.

Smog can be dangerous because it makes things difficult to see and causes traffic accidents. It also makes it difficult for some people to breathe and can cause lung disease, such as bronchitis. London was famous for its smog. Eventually a law was passed which only allowed smokeless fuel to be used by industry and in homes.
