Question

Local ranchers have expanded the grazing area of their cattle. How will this impact the river that runs along their lands?

A. Animal wastes will run into the river with every rainfall.

B. This will not impact the river significantly.

C. Animal wastes will decompose and add important nutrients to the river.

D. Cattle will pollute the river by using it as source of water

Answer 1

Out of the choices given, when the grazing area is expanded, it will impact the river by the animal wastes running into the river with every rainfall. The correct answer is A. 

Answer 2

The right option is; A. Animal wastes will run into the river with every rainfall.

The expanded grazing area of cattle will negatively influence the river that runs along the land as animal wastes will be transported into the river with every rainfall. The release of animal wastes in the river can affect the water quality of the river because of the pathogens that are present in cattle feaces. Also, it will provide increased potential for toxic algae blooms in the river.
