• The proposed law will protect the lake because plant roots between the wetland and the lake will stop pollution from entering the lake

• The proposed law will not protest the lake because animals that live in or near the lake will add pollution to the lake

• the proposed law will not protect the lake because groundwater will carry pollution directly into the lake

• The proposed law will protect the lake because the high elevation of the water table will block pollution from entering the lake

• excess crop fertilizer is carried by surface runoff into the river, causing excess growth of water plants and algae

• escess crop material builds up on the river banks, slowing the movement of river water

• crops reduce erosion, increasing the amount of soil entering the river

• crops absorb pure water from the soil, causing the remaining water to contain more salt
