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.Know More
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 causes of radioactive pollution include nuclear power plants, energy factories, mining, improper waste disposal, nuclear testing, terrorism and other human activities. Radioactive pollution can enter the environment by water, air and soil contamination. Regardless of its origin, radioactive pollution is particularly hazardous to animals and the environment.Full Answer >
River pollution comes from a variety of different sources, including agricultural operations, industrial discharge, wastewater treatment plants and storm water runoff, that carry pollutants into waterways. Sources are classified as point sources if the pollution comes from a single, identifiable source and nonpoint sources if the pollution is the result of runoff over a wide area. Since rivers draw from many sources, they may contain many different pollutants.Full Answer >
Ocean pollution is caused by numerous industrial and domestic activities, which include oil spills, garbage dumping, sewage and factory-waste disposal and the use of toxic pesticides. These activities pollute the oceans through drains, rivers and direct dumping. According to All Recycling Facts, land-based activities account for more than 80 percent of ocean pollution.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 >
