What are the causes of the water pollution that threaten South Asia today?
overpopulation, growing cities, damming of rivers, and the need for more irrigation
burning down of forests, building of new factories, and more cars
the use of major rivers in religious festivals
pollution in the Himalayan streams that drain into the region’s major rivers
A?
I agree.
No, A is not the correct answer. The causes of water pollution that threaten South Asia today include overpopulation, growing cities, damming of rivers, and the need for more irrigation. These factors contribute to the discharge of untreated sewage, industrial waste, and agricultural runoff into water bodies, leading to pollution.
Option B is also not the correct answer. Although burning down of forests, building of new factories, and more cars can contribute to overall pollution, they may not specifically be causing water pollution in South Asia.
Option C is an incorrect answer as well. While the use of major rivers in religious festivals may have some impact on water pollution, it is not one of the main causes threatening South Asia.
Option D is the correct answer. Pollution in the Himalayan streams that drain into the region’s major rivers is a significant cause of water pollution in South Asia. Industrial activities, mining, and agricultural practices in the Himalayan region contribute to the pollution of these streams, which eventually flow into the major rivers of the region.
