pollute the rivers

For example: the air pollution, the forest and the vegetation are destructed, the waste water pollute the rivers, trash everywhere obviously, our survival encounters the threat!

如：大气污染，森林和植被遭到破坏，废水污染河流，垃圾到处可见，我们的生存遭到威胁！

Such actions as discharging waste water to rivers not only pollute the environment but also become a danger to people's health.

像排放污水这样的行为不仅污染了环境，还成为了人民健康的威胁。

We can pollute the air with acids, the rivers with sewage, the seas with oil.

我们会用酸污染空气，用污水污染河流，用石油污染海洋。
