Have you ever seen black sm pollution.oke?coming outof factory chimneys,turning the sky a dirty grey colour.this is air pollution.cars,trucks,buses release gases and particles that pollute the air,too smoke from fire and chullah also pollutes the air.
Land pollution,water pollution and even noise pollution are also big problems.factories and ordinary people thoughtlessly dump rubbish and waste on land or in water. Farm pesticides kill insects, and create land pollution. And noise pollution is created by loud machines and sounds of homs.
Ocean life isn't safe from pollution. Sometimes people are hired to clean up polluted seashore after an oil spill. Sometimes ships carrying petroleum have ccidents and their oil spills into the ocean.
