Today, we talked about pollution and the different types of it. We learned that toxic pollutants are like paint and battery acid that aren't properly disposed of. We learned about sediment and how if too much is in the water, that the water becomes turbid and the light can't reach the plants at the bottom of the water, causing algae to form and vegetation to die. We also learned about natural pollutants like manure and excessive nitrogen. A big part this pollution is golf courses. They use all the chemicals they can to keep their greens green. The last one is bacterial pollution. The main cause of this is farming. Manure runs off of fields and out of coops and such and can run into rivers and streams.
