Agricultural activities - Cause of Air Pollution
Agricultural activities too are a major cause of air pollution. About 60 to 65% of carbon dioxide is produced from burning of forests and savannah grassland to clear areas for pastures and cropland and 40% of methane is produced from paddy fields, guts of live stocks and also from burning of biomass.
Methane is produced in the guts of livestock on break-down of organic matter by anaerobic bacteria. Nitrous oxide is produced from nitrogen fertilizer livestock wastes and biomass burning. Hence, we find that all the primary occupations of man- agriculture, animal rearing, and lumbering, mining etc. cause pollution of air.
