dioxin-like chemicals have been found in the general US population that are "at or near levels associated with adverse health effects." The EPA report confirmed that dioxin is a cancer hazard to people; that exposure to dioxin can also cause severe reproductive and developmental problems (at levels 100 times lower than those associated with its cancer causing effects); and that dioxin can cause immune system damage and interfere with regulatory hormones.

polluted water? Well‚ that’s a true fact! There are three main reasons that we need to prevent water pollution.
