Question

Conserving the quality of available water is a high priority world-wide. There are many countries where the water supply is reaching dangerous levels of contamination. For example, the longest river in China, the Yangtze, is less than 5 years from death if nothing changes. How could the loss of this river have a negative impact not only the environment in China but across the region?

A) The pollution is high in organic material so it will make the area more fertile.

B) The death of the organisms in this river will open up niches for other organisms to replace.

C) Since the Yangtze empties into the Sea of Shanghai the pollution will travel and have effects on surrounding countries.

D) The loss of such a river is so minor in the ecosystems of the area, the impact will be low and not a danger to surrounding areas.

Answer 1

The correct answer is option C, Since the Yangtze empties into the Sea of Shanghai the pollution will travel and have effects on surrounding countries.

Reason - Reason –

The Yangtze river is impure and thus its entire ecosystem will get destroyed as the all the marine animals in it will die due to the pollution of the river. Now, since this river travels to other water bodies like the Sea of Shanghai, the pollution will also get introduced in the sea along with the deteriorated ecosystem of the river. This will lead to magnification of the issue of pollution from one deteriorated water body to other water body.

Answer 2

The correct option is C. The surrounding countries will also share from the negative effects of the loss of Yangtze river.
