It keeps breathing problems and lung cancer increasing. It also causes the global warming and acid rain. Because of these bad effects, we should reduce air pollution by using less fossil fuel, cutting down the amount of pesticides for farming and smoke from factories.
power plants, manufacturing facilities, waste incinerators, furnaces and other types of fuel-burning heating devices (the burning of fossil fuels such as coal, oil, natural gas):nhà máy điện, cơ sở sản xuất, lò đốt chất thải, lò nung và các loại thiết bị đốt nhiên liệu khác (đốt nhiên liệu hóa thạch như than, dầu, khí đốt tự nhiên)
agricultural activities (the use of insecticides, pesticides, fertilizers):hoạt động nông nghiệp (sử dụng thuốc diệt côn trùng, thuốc trừ sâu, phân bón)

deforestation → the need for pastureland and growing fields → the removals of trees:tàn phá rừng → sự cần thiết của đồng cỏ để chăn nuôi gia súc và các cánh đồng trồng trọt → việc chặt cây
waste → landfills → generate methane (greater demand for dumping grounds a significant source of methane production):chất thải → bãi rác → tạo ra khí mê-tan (nhu cầu chỗ đổ rác tăng → là nguồn sản xuất khí mê-tan đáng kể)
population growth, urbanisation:gia tăng dân số, đô thị
