Natural pollution comes from natural sources like release of methane by cattle and paddy fields, carbon dioxide from plants and animals, dust storms, nitrogen oxides, ozone, volcanic eruptions, emission of natural gas, sol erosion, ultraviolet rays,etc. Mercury is not a cause of natural pollution.

Some of the natural sources of air pollution are organic compounds from plants, sea salt, suspended soils and dusts (e.g. from the Sahara). Other natural sources are released during catastrophes such as volcanic eruptions and forest fires.

Causes of Water Pollution

• Volcanoes. With large eruptions, volcanoes tend to change the climate for years.
• Animal Waste. The animal waste that comes out from the dairy and the poultry farm adds to water pollution.
• Algae.
• Floods.

A natural pollutant is a pollutant created by substances of natural origin such as volcanic dust, sea salt particles, photochemically formed ozone, and products of forest fibres, among others. Source Publication: Glossary of Environment Statistics, Studies in Methods, Series F, No.

Man-made pollutants can threaten human health and compromise the natural ecosystem and environment. Man-made pollution is generally a byproduct of human actions such as consumption, waste disposal, industrial production, transportation and energy generation.

• Burning of fossil fuels: Sulfur dioxide released by the burning of fossil fuels like coal, petroleum is the major cause of air pollution.
• Agricultural activities:
• Exhaust from factories and industries:
• Mining operations:

Humans pollute the air, land, and sea by burning fossil fuels, overusing chemicals and pesticides, and creating sewage run-off. The health consequences of that pollution are clear: Air pollution causes some 8.8 million deaths annually worldwide.

we should avoid soil pollution because it causes harm to nutrients which is present in soil . soil pollution decreases soil fertility. this also cause harm to crops . soil pollution can cause harm to animals who graze .

Even when soil is not being used for food, the matter of its contamination can be a health concern. Some soil contaminants increase the risk of leukemia, while others can lead to kidney damage, liver problems and changes in the central nervous system. Those are just the long term effects of soil pollution.

Long Term Diseases Cancer, including leukemia – caused by the contact with soils contaminated with chemicals (e.g. gasoline, benzene) Nervous system damage – caused especially by the presence of lead (Pb) in soil, and affecting especially children. Neuromuscular blockage and depression of the central nervous system.

Soil pollution comes from different sources including agriculture and animal husbandry. Some of the agricultural practices lead to soil pollution. They are animal wastes, use of long lived pesticides, herbicides, fungicides, nematocides, etc. fertilizers and some agricultural practices.

Effects of Soil Pollution on Human Health Living, working, or playing in contaminated soil can lead to respiratory diseases, skin diseases, and other health problems. Diseases caused by soil pollution include Irritation of the skin and the eyes, Headaches, nausea, vomiting, Coughing, pain in the chest, and wheezing.
