Most of them are normally found in forests, backyards, abandoned swimming pools and buildings. The open dumps have one major disadvantage especially in densely populated areas. The open dumps allowed the communication of the…

The decomposition of garbage very much involves the work of bacteria. The rate of decomposition is enhanced by the presence of leachate. As the wastes are degraded by the bacteria, gases are emitted mainly methane. Methane is a greenhouse gas whose emissions pose a threat to the environment (WeGreen-USA, 2014)
The liquid that percolates or filters through the dump is referred to as Leachate. The sources of leachate would be rainwater or the liquids in the waters. Rainwater normally hit collected trash; pooling occurs and run off may ensue. The lacerate would thus become toxic since it will mix ground water (WeGreen-USA, 2014).
The landfills are the most commonly used method of waste disposal. The old landfills were mainly composed of a bottom liner and a cover. The old landfills failed to adequately prevent the contamination of the environment with wastes. The leachate was not collected hence it trickled down to the ground bringing about the contamination of ground water. In addition, the wastes were exposed to the environment hence attracting pests. The decomposition of older landfills took more time since cover of the landfills was not properly structured.
The modern landfill contains a leachate collecting system, a bottom liner and a cover. This minimizes the possibility of wastes escaping into the ground. The modern landfills are constructed with safeguards. The water is normally covered to avoid attracting the pests. In addition, compaction of the waste is carried out order to increase the density and stability. This means that more waste can be disposed of using the landfill method. Modern landfills are designed in ways that protect the environment from contamination. Landfills prevent hydraulic connections between the waste and the environment mainly ground water (WeGreen-USA, 2014)
The old landfills were not properly structured and allowed communication with the environment. This can be attributed to the poor ground layer, the

“It is society which disables physically impaired people. Disability is something imposed on top of our impairments; by the way we are unnecessarily isolated and excluded from full participation in society”

For example, exposure to chemicals, radioactive material, and drugs among other hazardous conditions may lead to failure in development of some body parts, stunted growth in babies as well as poor cognitive development.
Being a heavily industrialised county, the main sites that are responsible for contaminating drinking water include, chemdyne, feed materials production centre, skinner land fill, Armco incorporation, mat papers, among others. The key pollutants are
According to Spoolman & Miller (2011), a risk is the probability of suffering harm from a hazard that can cause injury, disease, death, economic loss or damage and is usually expressed as a mathematical
The movie “The Thin Man” explores a murder mystery with William Powell and Myrna Loy as the main characters. The movie presents the characters as severely addicted to alcohol drinking and this is a part of their personal style or natural behaviour in the movie.
