'Pollutes' in the Bible

So you shall not pollute the land in which you are; for blood pollutes the land and no expiation can be made for the land for the blood that is shed on it, except by the blood of him who shed it.

And the tongue is a fire. The tongue, a world of unrighteousness, is placed among the parts of our bodies. It pollutes the whole body, sets the course of life on fire, and is set on fire by hell.
