Every day, people do things that hurt the planet in different ways. First, many fishermen catch too many fish. This makes the number of fish in the sea smaller and smaller. Some fish may even disappear one day. Second, farmers use a lot of dangerous chemicals. These chemicals get into the groundwater and make it dirty. People and animals cannot drink the clean water anymore. Third, factories burn oil and gas to make energy. They produce a lot of harmful gases, which make the air dirty. Finally, people cut down too many trees to build farms. There are fewer forests now, and many animals lose their homes. These problems are very bad for the Earth. But we can still help. We can stop polluting the water and air, plant more trees, and use less plastic. Let’s work together to protect our only home. 1. What problem is caused by catching too many fish? A.
