Summary:
To survive, fish need food, clean water, clean environment, biodiversity, the right temperature for water, level of light, and oxygen. Some of the facilities near the Gray Area River may be causing the fish to die. The dams near the river may be killing off the fish's food, making them starve and forestry might cause erosion, making the fish blind and disable them from eating food. Boats might cause shade and change the required light for fish, and dams will probably affect the right temperature for the fish. Damming and forestry may be killing off the fish, destroying the biodiversity, and forestry might cause erosion, suffocating the fish. These are examples of things around the Gray Area River that might be killing the fish and other inhabitants of the river.
SP7: Arguing From Evidence:
I used evidence to defend my explanation. I answered that The Waterslide in the Gray Area was the facility most likely to be polluting the Gray Area River, providing that the fish started dying in the river following the Water Slide's creation. If other factors, such as logging and oil factories caused the fish to die, it would have happened as soon as that event happened. For example, the oil factories were built nearly 20 years ago, yet the fish started dying 5 years ago. If the oil factories caused the fish to die, wouldn't the fish start dying 20 years ago instead of 5 years ago? Also, other cases show that the Waterslide is causing the fish to die. The Bench Press News showed that Waterslide workers spilled about 250 gallons of chlorine into the Gray Area River, which caused the fish to start dying. Also, an experiment conducted by Juan Tuno showed that there were plenty of water fleas, vulnerable to chlorine, were found upstream the river where the Water slide might have spilled chlorine into, which meant that there was no chlorine there. This makes sense because the Waterslide is found near the downstream of the river, and not upstream. Juan Tuno also tested the amount of water fleas downstream the river, and found little to no water fleas, which meant that they must have died to the chlorine, showing that the Waterslide may have caused the fish's death.
Crosscutting Concepts: Cause and Effect:
To begin with, the Cause of the fish dying is probably because of the Waterslide pouring about 250 gallons of chlorine into the Gray Area River, and the Effect of the Cause is the fish dying. I can prove the relation ship between this Cause and Effect due to many sources showing that the Waterslide dumped chlorine into the river. One main source that shows that the Waterslide poured chlorine into the river is the emails that the Waterslide employees sent each other. One Waterslide employee said that they were going to dump a box full of water fleas into the river before 'the boy' (referring to Juan Tuno), in attempt to prove that the water was healthy. That action still didn't seem to do anything, since Juan Tuno still showed that there were very little water fleas downstream of the river, which meant that there might be chlorine in the river, killing the fish. One of the employees/employers also said that they hired a chemist to test the water on Tuesday night to test the river. During Tuesday night, the Waterslide also poured water from the river into holding tanks, and treated it with chlorine. This may have been done to hide the chemist from finding any chlorine from the river, due to the Waterslide consuming some of the river's water.
