Explanation:

South Asia and Southeast Asia are two neighboring regions in Asia. Both regions as a whole fall into the category of developing regions, as all of the nation sin them, apart from Singapore, are developing nations.

As most of the developing nations, the ones of South and Southeast Asia have big problems with pollution, especially with the air pollution. The problems are the biggest where there is higher concentration of people, thus the larger urban areas.

The majority of the air pollution comes from the fires, the factory waste, and the exhaust fro the motor vehicles. The pollution is so large that pretty much for the whole year there is smog in the larger urban areas. the breathing is very hard. Everyone that can afford uses gas masks when outside because the situation is so bad.

Whats even worse is that the governments and the local authorities don't seem to be very interested in solving the pollution problem. The main reason behind this is economic development, and in order to achieve it everything else is neglected.
