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.
