Consumption affecting the environment

Today, overpopulation is a serious issue in the world. To feed everyone, we need to make enough food. To make food, we have to cut down forests to make space for cattle and crops. This causes some species like tigers to become extinct because their habitat has been used by us humans. 

Also, many people drive cars, which release carbon dioxide. This is a chemical which influences the environment, causing global warming.

People use a lot of water; more than they actually need. This means that the groundwater levels are sinking and people are having trouble accessing water.
