However, human activities are causing a lot of damage to the environment. One of the biggest problems is pollution. Air pollution is caused by cars, factories, and power plants. It can make people sick and cause breathing problems. Water pollution is caused by chemicals and waste from factories and homes. It can kill fish and other animals that live in water. Another problem is deforestation. People cut down trees to build houses and make paper. This destroys the homes of many animals and plants. It also leads to soil erosion, which can cause floods. Global warming is another serious issue. It is caused by greenhouse gases, which trap heat in the atmosphere. This makes the Earth's temperature rise, which can cause ice to melt and sea levels to rise. But there are things we can do to protect the environment. We can reduce pollution by using public transport or riding a bike instead of driving a car. We can recycle paper, glass, and plastic. We can also plant more trees and save water. Everyone can make a difference. If we all work together, we can protect our environment for future generations. 根据短文内容，选择最佳答案。 （ ）1.What does the environment provide us with? A. Money and cars. B.
