Question

Using complete sentences, identify and explain two causes of water pollution, two causes of air pollution, and the effects of both in South and Southeast Asia.

Answer 1

Water pollution in South and Southeast Asia is mainly caused by point source and nonpoint source pollution, while air pollution stems from industrial emissions and vehicle exhaust. These pollutants harm local ecologies, human health, and contribute to global environmental issues like acid rain.

Step-by-step explanation:

In South and Southeast Asia, the two main causes of water pollution are point source pollution, such as untreated sewage and industrial effluents, and nonpoint source pollution, like agricultural runoff containing pesticides and fertilizers. Air pollution is primarily caused by the release of smoke and dust from industrial activities and the emissions from vehicles. These pollutants cause significant harm to the environment including the ecology of rivers and lakes, and human health, manifesting in waterborne diseases and respiratory issues. Additionally, air pollution contributes to acid rain, which can further degrade water quality and soil fertility.

For example, in Jakarta, Indonesia, water pollution has been observed to have detrimental effects on both ecology and human health, as depicted in Figure 12.27.1. In countries like South Korea, air pollution from industrial centers and cities contributes to high levels of acid rain. The effects of pollution do not only affect the immediate area but can have far-reaching impacts on the global ecosystem.

Answer 2

Answer: One of the major environmental concerns in South and Southeast Asia is pollution. Water pollution in the region is caused by industrial waste and untreated sewage. Industrial waste often travels downstream and affects the water supplies in cities and farms. Cities often dump sewage into rivers without treating and cleaning the water. The untreated water contains bacteria or parasites. People can become very sick when they drink the polluted water or use it to grow crops. People may end up with severe diseases or long-term health conditions. Air pollution is caused by slash-and-burn farming, fires, and airborne chemicals from vehicles and industries. The smoke and haze released into the air can travel hundreds of miles and affect entire regions. People can become ill when they breathe the air.
