Most of the major rivers in Southeast Asia are fed by melting glaciers

The economies of these countries depend heavily on the export of ice

None of the above; People aren’t affected by the presence of mountain glaciers

Detailed explanation-1: -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.
Detailed explanation-2: -CO2 emissions: the atmospheric concentration of carbon dioxide and other greenhouse gases (GHGs) produced by industry, transport, deforestation and burning fossil fuels, amongst other human activities, warm the planet and cause glaciers to melt.
Detailed explanation-3: -Due to climate change, the area of high-altitude glaciers is decreasing, which leads to an increase in the area of glacial lakes. This poses a potential threat to infrastructure and people’s lives in the valleys. Floods caused by breakouts of glacial lakes threaten an increasing number of people.
Detailed explanation-4: -Rapid melting of glaciers can lead to flooding of rivers and to the for-mation of glacial meltwater lakes, which may pose an even more serious threat. Continued melting or calving of ice chunks into lakes can cause catastrophic glacial lake outburst floods.
