Ye Olde Water Cycle

Last Thursday, before Omega left for the End-of-the-year Field trip to Frog Bridge Day Camp, Mrs. Rousseau had us do an activity showing how much the humans affect the water cycle. It went like this: before the humans, water from the aquafers, oceans, streams and rivers, and reservoirs evaporated into clouds, which then released the water back in to the above systems. But, when the Industry and Agriculture, most of the water got polluted with pesticides and waste from the factories. The animals would drink the polluted water from the rivers and streams, and in turn, get poisoned. The aquatic creatures also get harmed. The pollution would gum up the fishes gills, and in turn, the fish will suffocate. The pesticides will not only harm animals relying on the streams and rivers to survive, but it also over stimulates algea growth, which blocks the sunlight from getting to the bottom of the insert body of water here , and then fish and other aquatic creatures will die. I got this information from the following site:
