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.
人們通過污染對環境造成了很多損害。工廠將有害化學物質排放到空氣和水中,汽車也加劇了空氣污染。人們還不當地丟棄廢物,這污染了土地和水。塑料產品是一個大問題,因為它們不容易分解。學生可以在科學課中學習這些問題,這對於理解污染的影響非常重要。
