Air pollution is a serious problem causing death in Vietnam, such as Hanoi and Ho Chi Minh City. The cause is from vehicle emissions and factories. This causes many respiratory diseases and reduces the quality of life.

To solve this problem, we need to control emissions from vehicles and factories more strictly. In addition, people should use public transport, ride bicycles or walk to reduce pollution. Planting trees is very important because they help filter the air and create a cleaner environment. Only when everyone acts together can we improve air quality.
