All life on Earth depends on the environment. The natural resources that come from the environment include food, water, plants, and minerals. Sustainability is the idea that humans must interact with the environment in a way that ensures there will be enough resources left for future generations.

There are now more than seven billion people on Earth. These billions of people use the planet’s resources every day. Human activity has harmed the environment in many ways. Some of the resources that people use cannot be replaced once they are used. People also use huge amounts of fossil fuels, which has led to pollution and other problems. Sustainability addresses ways to protect and conserve the environment.
