What is the biggest form of pollution?
Most ocean pollution begins on land. Much of this runoff flows to the sea, carrying with it agricultural fertilizers and pesticides. Eighty percent of pollution to the marine environment comes from the land. One of the biggest sources is called nonpoint source pollution, which occurs as a result of runoff.
What are 3 causes of water pollution?
Discharge of domestic and industrial effluent wastes, leakage from water tanks, marine dumping, radioactive waste and atmospheric deposition are major causes of water pollution. Heavy metals that disposed off and industrial waste can accumulate in lakes and river, proving harmful to humans and animals.
Which country has no pollution?

What cause the most pollution?
Most of this air pollution we cause results from the burning of fossil fuels, such as coal, oil, natural gas, and gasoline to produce electricity and power our vehicles. Carbon dioxide (CO2) is a good indicator of how much fossil fuel is burned and how much of other pollutants are emitted as a result.
What are the top 10 pollutants?
The top 10, in alphabetical order, are: artisanal gold mining; contaminated surface water; contaminated groundwater; indoor air pollution; metals smelting and processing; industrial mining; radioactive waste and uranium mining; untreated sewage; urban air quality; and used lead–acid battery recycling.
Which is the most dangerous type of pollution?
