We live in the environment that is polluted, we need a healthy environment in order to survive. We need to protect the environment now to help prevent health problems, and to preserve the Earth for our children. We all know that pollution from factories and cars can cause huge damage to the atmosphere. It makes the air dirty. Breathing this air causes lung diseases, particularly for children and the elderly. We need to control the amounts of pollution we produce in order to prevent health problems. Furthermore, we also need to pay attention to the ecosystem. Plant life, animal life, and people all depend on each other. Polluted environment disturbs our ecosystem. For example, pollution might cause certain kinds of plants to die. If these plants are food for some certain kind of animals, they will die too. If people use these animals as food source, there could be a big problem. To avoid the big problems, factories should pollute as little as possible. If

we do not protect our environment, it will continue to get worse. That leads our children to suffer the consequences. The air and water will be dirtier, natural resources will become scarcer, and more plants and animals will die. Even worse, their well-being will be threatened. In short, with contaminated air to breathe, an unhealthy ecosystem, that's the bad future for our generation, the human race will not survive. That is why protecting our environment is crucial.
