Water Pollution
Bayani Gaba-gaba
Water is the universal solvent, which is exactly why it is so easily polluted. Almost anything we spill, flush or wash away ends up dissolved or suspended in a river, lake or sea. A single careless factory outfall can poison a fishery; a field of fertiliser can suffocate a whole lake; untreated sewage can spark an outbreak of deadly disease. Clean water is precious, and keeping it clean is one of the central problems of environmental management.
In this lesson you will learn where water pollution comes from, how it harms both people and ecosystems, and what can be done about it. You will follow the sinister chain of eutrophication, see how toxic chemicals build up inside living things and magnify up a food chain, and weigh the strategies, from better sanitation to tough laws, that keep our water fit to use.
