How Do Humans Depend on Natural Habitats?
Humans depend on natural habitats. Look at some ways natural habitats help us.
Wood and Paper Products

These are made from trees that grow in forests. Wood is used to build homes and furniture. Wood is also used to make paper, paper towels, and tissues.
Oxygen

Oxygen is an important part of the air we breathe. Humans can not survive without it. Plants and trees make oxygen. We need forests to make oxygen.
Food

Most of our food comes from farms. In some places, people get food from nature.
They hunt animals. They gather plants from nature.
Flood Control

When lots of rain falls quickly, floods can happen. Rainwater flows into rivers and streams. These can overflow into the land around them. Floods can damage people’s homes. They can destroy the crops in farmers’ fields. Wetlands, such as marshes and swamps, help control floods. Wetland plants act like sponges, absorbing much of the water. Without wetlands, floods would be worse.
Medicine

Many ingredients for medicine come from plants. Many of those plants are found only in natural habitats such as forests. For example, willow bark relieves pain. It is a chemical used in Aspirin®. New plants are being discovered. Some may be used to make medicines.
Recreation

Natural habitats are fun. Whitewater rafting happens on a river. Downhill skiing needs a mountain. Lakes are great for swimming, boating, and waterskiing. Lots of people enjoy hiking or camping in forests. These activities need natural habitats.
