People have done a lot of damage to the environment through pollution. Factories release harmful chemicals into the air and water, and cars add to air pollution. People also throw away waste improperly, which pollutes the land and water. Plastic products are a big problem because they don't break down easily. Students can learn about these issues in science classes, which is important for understanding the impact of pollution.
人们通过污染对环境造成了很大的损害。工厂向空气和水中释放有害化学物质,汽车也加剧了空气污染。人们还不当处理废物,这污染了土地和水源。塑料产品是一个大问题,因为它们不容易分解。学生可以在科学课上学习这些问题,这对理解污染的影响非常重要。
