The causes of pollution are excessive use of natural resources, over industrialization, increase in global population and globalization. The use of chemicals, such as pesticides and weedicides, cause soil pollution.Continue Reading
The introduction of pollutants into the air, water or soil is called pollution. The burning of fossil fuels to power industries and vehicles is a major cause of pollution. Generating electrical power through thermal power stations releases huge amounts of carbon dioxide into the atmosphere. As global population increases, the demand for fossil fuels increases causing additional pollution.
Water is polluted through the use of toxic chemicals that are then discharged into water sources such as lakes, rivers and streams. Underground water is also polluted due to such toxic chemicals.Learn more about Pollution
Some common causes of air pollution are second-hand tobacco smoke, agricultural fertilizer application, fuel combustion from transportation, and industrial processes such as mining, fuel refinery and chemical manufacturing. Other sources of air pollution include livestock waste, solvent application for degreasing purposes, commercial cooking and naturally occurring events such as wildfires.Full Answer >
Soil pollution is caused by a variety of anthropogenic activities, but mining activities, chemical spills and improper disposal of toxic chemicals are the most common causes. Some contaminants, including salts, metals and alcohols, are present in the soil naturally. However, if these chemicals build up to toxic levels, they may become a natural form of soil pollution.Full Answer >
Some of the major causes of air pollution include burning of fossil fuels, agricultural activities, exhaust from industries, vehicle fumes, mining operations and indoor pollutants. Air pollution has a negative impact on the environment and life in general.Full Answer >
The National Oceanic and Atmospheric Administration divides the causes of water pollution into two categories: point source pollution and non-point source pollution. Point source pollution comes from a single, identifiable source that discharges pollutants directly into a body of water or after undergoing treatment processes. Non-point source pollution comes from multiple locations that are hard to distinguish and travels some distance before entering a water body.Full Answer >
