Answer:
animal wastes and fertilizers
Explanation:
The majority of the nitrates that are polluting the rivers come from the animal wastes and from the fertilizers used in the agriculture. The increased amounts of nitrates in the rivers causes eutrophication. This basically means that the water is becoming over-saturated with nutrients. This leads to the spreading out of the algae. As the algae spread out more and more, they cover the surface part of the water, so large portions of the rivers do not receive sunlight, which kills of the organisms that use photosynthesis. Further, the algae reduce the amount of oxygen in the water, often resulting in dying out of the fishes. It is a chain reaction that leads from one thing to another and the end result is devastating.
Answer:
Erosion can cause water in the rivers to become heavily polluted. The water might carry pesticides, heavy metal ions and other toxic wastes. When this water will be used for irrigation purposes, the growth of plants will be heavily affected by them.
When humans use water this contaminated water from the rivers, it will led to many diseases in humans. Also, the wild- life animals which depend on this river might take in toxic compounds due to which they might die.
