The aim of genetic engineering in crops is to improve beneficial crop characteristics and traits. Genetically engineered foods can have higher nutrient content and can survive in varied climatic conditions as designed by scientists. Genetic engineering involves putting new genes of desirable characteristics into a crop. The gene may be from a plant of different species or an animal. The long term effects and short term effects of genetically engineered foods may not be fully known but it reduces the costs of production (Vasil, 1998).
Crops can be genetically engineered to be drought resistant, disease resistant, and pest resistant. Reduced chemical use in crop management conserves the environment. They can also be genetically manipulated to contain extra nutrient s. The crops will require lower maintenance and farmers will benefit from crop-protection transgenic strategies (Wambugu, 1999). Increasing food security will stabilize their economies and quality of life. Most people in arid and semi arid countries depend on single food crops and endowing these plants with more nutrients through genetic engineering will reduce incidences of food malnutrition. Most opponents of genetic engineering state that it is ethically wrong and that it is harmful. Adequate Legislation can ensure ethical practices and strict adherence to regulations can be monitored effectively. I conquer that more research should be done to understand the long term effects of genetically engineered crops on the ecosystem and on human health.

a. Experimental animals are the most reliable means of detecting toxic and chemical properties risk on health of humans as human data is very limited in relation to the compounds being analyzed.
b. The dose-response curve illustrates the change in an organism caused by different levels of exposure in a given time. The route of administration and the exposure time is crucial in understanding the response relationship. The response curve help toxicologists determine safe and hazardous levels for the compounds under study.
c. LD50 is the amount of substance required to kill 50% of the test population usually measured in mg/body weight. A substance with a high LD50 is safer because it requires higher concentration to cause 50% death to the test population. A substance with a low LD50 requires very little concentrations to cause 50% death in test population and hence is more lethal.
I support the precautionary principle because it is our duty to prevent some threats of damage, particularly threats of serious environmental damage even when we lack scientific certainty about their existence or magnitude (Raffensberger and Tickner, 1999). Human instigated risks to the environment can be termed as inequitable (John, 2010) as it is our moral obligation to protect the environment. The costs and effects of damage to the environment are so serious that compensation and remedial action is impossible. If species become extinct, it is a loss of diversity that is irreplaceable. The costs of damage far outweigh the benefits and considering the advance in technology very many new artificial compounds are invented and they should be strictly regulated to prevent harmful effects to human health and the environment.

..., 2008). 5. Chlorine Poisoning from Chlorinated Water Chlorine is widely used to treat drinking water in order to kill pathogens that cause typhoid, dysentery, and cholera. The amount that is applied to human drinking water may not kill viruses, cysts and worms. Thus chlorine should be used in addition with filtration processes in order to disinfect human drinking water. Another alternative is to undertake super chlorination which is followed by a dechlorination process to eliminate any chlorine residues. Countries which have access to chlorinated water have low death rates as compared to countries where water is unsafe for drinking as the water is not treated. According to the world...

...? 28 June, “The Climate Emergency” by Al Gore Analysis: In this article, (Al Gore) has narrated experiences from his personal life in an attempt to make the audience believe that the climatic change has inculcated certain urgency in the attitude of people which is the root-cause of numerous confusions around us. The term “climatic emergency” asserts that there is an environmental crisis going on which cultivates a strange urgency. The inability of a vast majority of people to realize this urgency is the focus of Al Gore’s discussion. People generally choose two reasons to stop being defensive, i.e. they either overestimate the size of earth or the problem of global warming. Increase in the level of CO2 in the air has been... 28 June, “The...

...appreciated from the historic times. The need for regulation has increased with the warnings of global warming and threatening environmental safety. If this issue is studied particularly with reference to Canada, in the year 2000 itself, according the Canadian Council of Ministers of the Environment, Canada wide standards for mercury emissions were particularly issued which noted that mercury levels in fish pose large unquantified risk to fish eating wild life1 and such impact needs to be considered for human beings who consume such fish as well. Mercury travels long distances and is deposited far from the source of emission. In fact according to Canadian sources, only 4% of mercury deposits in Canada...

...Human Health and the Environment Most people in America prefer warm weather, because they want to enjoy good health and live longer. People who live in moderate temperatures find the transition from warm to cold difficult. Moreover, the countries that are in the list of UN which are considered as the most livable, are in the regions of moderate to sub Arctic climates. The studies by Dr. Thomas Gale Moore, who is a fellow at Hoover Institution, and the author of Climate of Fear: Why We Shouldn’t Worry about Global Warming, and Special Report: Global Warming Benefits May Exceed Risks, prove that in warmer temperatures, humans will live longer and avoid certain sicknesses .He further discusses the possible risks and benefits of warm... ...
