Because of all of these effects, we should stop doing water pollution in order to keep animal species, and ourselves, from dying out. If we stop throwing our trash into the ocean and rivers, the water will eventually get cleaner and better to drink and live in. You can also use the 4R's (recycle, reuse, reduse, and recover). Ships and boats should stop pouring oil over the sides of their boats into the ocean. Farmers and gardeners should stop using chemicals to help their plants, fruits, and vegetables grow better.
