Synthetic Dyes and Public Health
Synthetic dyes are dangerous in different ways. They pollute the drinking water and the fields we grow our food on. Factories dump their chemical waste into rivers causing a lot of this pollution: These factories are usually next to large waterways (rivers or lakes) because making and using synthetic dyes takes a lot of water. Therefore, the factories become a threat to these waters – and to the people and animals that live near them because the poisoned water is unsuitable for drinking, growing food, or raising fish for example.
