According to Cornell University, bioremediation is the use of biological organisms to help clean contaminated or polluted environmental sites, such as the site of an oil spill. In nature, many biological organisms contribute to the cleanup of pollutants through a process called biodegradation. Bioremediation encourages that natural process, as it employs biological organisms to solve environmental problems.Know More
According to Wikipedia, bioremediation includes phytoremediation, which uses plants to reduce and remove pollutants, and bioventing, which enhances the activity of microorganisms by increasing the flow of oxygen. Other examples of bioremediation include bioleaching, landfarming, composting, bioaugmentation, rhizofiltration and biostimulation.
Wikipedia explains that bioremediation uses naturally occurring organisms to break down hazardous substances into less hazardous substances. Bioremediation may occur on its own, or may only effectively occur through purposeful intervention. Cornell University states that bioremediation provides techniques for cleaning pollution that may be safer and more cost effective than alternative solutions, such as incineration of contaminated materials or landfills to contain hazardous waste .
Bioremediation often involves ways to enhance the growth of pollution-eating microbes which already exist at the contamination sites; however, sometimes specialized microbes are added to degrade the contaminants. Both of these methods have the advantage of not requiring large quantities of soil, sediment or water to be removed or relocated before it can be treated.Learn more about Pollution
Nonpoint source pollution includes agricultural chemicals, animal waste and urban runoff. Unlike pollution that traces to a single sources such as a factory, nonpoint source pollution comes from many different locations. Runoff water from storms carries the pollutants to streams, lakes and rivers.Full Answer >
Examples of degradable pollutants are sewage, paper products, vegetables, juice, seeds and leaves. These are pollutants that are broken down naturally by micro-organisms and are not harmful to the environment. Degradable pollutants are often used as fertilizer.Full Answer >
Bioremediation is a method of waste management that entails the use of organisms to neutralize pollutants that pose risks to the environment and to human beings. It has become one of the most effective ways of cleaning polluted soil and water.Full Answer >
Articles written about ocean pollution are intended to raise awareness about this issue and to promote ecological conservation efforts to reverse pollution trends. According to the activist group The Ocean Project, increased awareness of ocean pollution has been shown to change public attitudes regarding conservation efforts and government policies.Full Answer >
