Water is a chemical compound that is formed by bonds between oxygen and water molecules. Its property as a universal solvent however leads to many dissolves matter in it and this defines its pollution when the dissolved matter is harmful…

Water cycle that consist of material flow on earth’s surface to water masses are some of the causes of water pollution as the flows collect materials into water bodies and are vulnerable to intentional pollution through domestic and industrial waste disposal. This paper discusses environmental effects of organic waste pollution and reviews an article that uses toxicology to investigate the impacts of water pollution on the natural environment. Effects of organic waste pollution on the natural environment Organic discharge into water bodies has varying effects on the environment. One of the effects of organic pollution is the disintegration of organic matter to changed odour and taste of water. Effects of continuous degradation are accumulation of compounds such as hydrogen sulphide and mercaptans and this leads to gradual increase in changed odour and taste of water that may not be suitable for sensitive flora and fauna. Organic pollutants also destabilize oxygen concentration in water masses. Many factors lead to this shift from equilibrium of water concentration. Processes of organic components of water such as photosynthesis and respiration uses oxygen and may change oxygen concentration in water. Photosynthesis may increase concentration beyond its equilibrium while respiration may reduce the level of concentration. Anaerobic respiration and oxidation of organic pollutants are other factors that can reduce oxygen concentration in water. ...
Insufficient oxygen in water may also cause death of aquatic animals. Such deaths further leads to accumulation of organic compounds in water and worsen the problem with oxygen concentration. Death of plants and animals in the water bodies also generate aesthetic effect besides increasing water turbidity (Goel 2006, p 116- 120). Organic pollution also affects levels of production of aquatic plants and animals. As the pollutants begin to invade water bodies, aquatic plants and animals benefits from nutrients that the organic pollutants may contain and this leads to high rates of photosynthesis and respiration among other processes. Increased concentration of organic pollutants however have adverse effects on aquatic lives as respiration rates increase and this leads to aesthetic effect and instability in oxygen concentration. Accumulation of organic pollutants also increases concentration of chemical compounds such as hydrogen sulphide and ammonia, chemicals that have adverse effects on some plant and animal species such as phytoplankton. High levels of organic pollution are also a threat to biodiversity. At normal water conditions, without organic pollutants, all aquatic plants, and animals are able to survive and their populations are constant. High levels of pollution however threaten the lives and less tolerant plants and animals die. Some plants and animals may however be tolerant and survive the harsh conditions due to the pollution. Consequently, aquatic life will consist of the tolerant species that may only be few. Loss of biodiversity from the pollution can also be permanent, unless artificial measures such as reintroduction of the extinct species upon resumption of normal condition in the polluted aquatic environment.

The researcher of this paper discussed environmental pollution in four categories: air, water, land and noise. Solutions to these types of pollution have been indicated, with the government called upon to protect the environment through policy implementation in support from the public and other stakeholders.
The usual methods of disposal have become insufficient in controlling the growing waste production. Land filling and burning are the most accepted actions on solid waste management, however both could negatively impact nature due to the harmful leaks and gases generated from such procedures.
These substances change the characteristics of the environment thereby posing a threat to the existence of humans, animals and other organisms. These pollutants can be primary or secondary in nature. Primary pollutants includes those which are directly released into the atmosphere such as from power generating plants while secondary pollutants are those which result from the chemical reactions that occur between the primary pollutants and the other elements present in the atmosphere resulting in their transformation to secondary type pollutants (Air pollutants General Overview).
Myriads of deaths occur as a result of health effects related to pollution. The effects range form mild discomforts to chronic diseases such as cancer. Human health has been endangered to large extents. Thus, the effects of pollution to the world are self-evident.
Since air pollution has serious effects to the human health as well as other living organisms, there have been increasing concerns on how to prevent it or at least mitigate its effects in the world (Liu 11). National governments, international organizations, and individuals have developed policies and approaches of addressing the challenge of environmental degradation, which air pollution is a main contributory factor (Agarwal 17).
This caused increased demand for energy that saw the exploitation of oil, coal and natural gas sources at increased rates around the globe. In the UK for instance, Kaiser and Pulsipher (2007) approximate the number of oil and gas installations at 289, two of which are found in deep water.
Resources are allocated based on the interaction of market forces especially the demand and supply as the market forces with no external interference. It's the opposite of centrally managed economy where the government's decisions control the operations of the market activities.
The author asserts that there are several methods that can be applied in the collection of solid waste. One of the methods used in the collection of solid waste is curbside collection, which entails the placing of closed containers on the roadside. Solid waste is put inside the containers; upon emptying.
The author highlights the importance of the protection of environment and human health from persistent organic pollutants, preservation and protection of marine environments. He examines different pollutants that are caused by human beings through release of toxic substances and hazardous chemicals into the natural environment.
