Trả lời câu hỏi : 1) What will people happen if they don't breath ? 2) What causes the problem of air pollution ?

Inefficient waste management and improper disposal of waste also contribute to air pollution by releasing harmful chemicals and gases into the atmosphere.

Air pollution can also be caused by natural sources such as wildfires, volcanic eruptions, and dust storms.

The problem of air pollution is caused by emissions from vehicles, factories, burning of fossil fuels, deforestation, and industrial activities.

If people don't breathe, they will suffocate and eventually die due to lack of oxygen.
