    River pollution occurs when pollutants are not removed from sewage and are discharged into the river. River water is a very important source of freshwater required to sustain life. We need a constant supply of fresh water for drinking, cooking and washing. Animals living near the river, as well as fishes and aquatic plants, also depend on clean river water.

       When heavy rainfall occurs, pollutants accumulated within the boundaries of the catchment area may be washed into river channels. These pollutants include a variety of agrochemicals like fertilizers and insecticides.

       Waste water containing cleaning detergents, oil and other pollutants like industrial waste may be discharged into the river channel through our drainage systems. Industrial waste may contain sulfur, resulting in increasing the acidity of the river water. Sometimes, rubbish such as plastic bags and bottles, are also washed into the river channel.

Read the passage below carefully, and then choose the best answer

Conservation conflicts arise when natural-resource shortages develop in the face of steadily increasing demands from a growing human population. Controversy frequently surrounds how a resource should be used, or allocated, and for whom. For example, a river may supply water for agricultural irrigation, habitat for fish, and water-generated electricity for a factory. Farmers, fishers, and industry leaders vie for unrestricted access to this river, but such freedom could destroy the resource, and conservation methods are necessary to protect the river for future use.

Conflicts worsen when a natural resource crosses political boundaries. For example, the headwaters, or source, of a major river may be located in a different country than the country through which the river flows. There is no guarantee that the river source will be protected to accommodate resource needs downstream. In addition, the way in which one natural resource is managed has a direct effect upon other natural resources. Cutting down a forest near a river, for instance, increases erosion, the wearing away of topsoil, and can lead to flooding. Eroded soil and silt cloud the river and adversely affect many organisms such as fish and important aquatic plants that require clean, clear freshwater for survival.

Question: Which sentence below is not correct?

A. Argument often surrounds how a source should be used, or allocated, and for whom.

B. A river may provide water for agricultural irrigation, habitat for fish, and water-generated electricity for a factory.

C. Conservation methods are incidental to care for the river for future use.

D. Farmers, fishers, and industry leaders vie for open access to this river.
