Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why would the loss of mountain glaciers be a bad thing?
A
Countries are dependent on plants and animals that live in those upper elevations
B
Most of the major rivers are fed by melting glaciers
C
The economy of these countries is dependent on the export of ice
D
People aren’t affected by the melting of mountain glaciers
Explanation: 

Detailed explanation-1: -The disappearance of glaciers also means less water for consumption by the population, a lower hydroelectric energy generation capacity, and less water available for irrigation.

Detailed explanation-2: -Introduction. Glaciers are moving bodies of ice that can change entire landscapes. They sculpt mountains, carve valleys, and move vast quantities of rock and sediment. In the past, glaciers have covered more than one third of Earth’s surface, and they continue to flow and to shape features in many places.

Detailed explanation-3: -The melting of glaciers seasonally releases melt water into tributaries of the Indus, Ganges and Brahmaputra Rivers, with glacial melt contributing up to 45 percent of the total river flow. Approximately 500 million people depend upon water from these three rivers to support agricultural and economic activities.

Detailed explanation-4: -There is still some uncertainty about the full volume of glaciers and ice caps on Earth, but if all of them were to melt, global sea level would rise approximately 70 meters (approximately 230 feet), flooding every coastal city on the planet.

Detailed explanation-5: -Melting glaciers add to rising sea levels, which in turn increases coastal erosion and elevates storm surge as warming air and ocean temperatures create more frequent and intense coastal storms like hurricanes and typhoons.
