Environmental Threats Essays -- essays research papers

Contemporary IssuesEnvironmental threatsOverpopulationEvery 20 minutes, the world adds another 3,500 human kick the buckets but loses one or more than entire species of animal or plant life - at least 27,000 species per year. ZGP July 1999 World population growth peaked at ab step to the fore devil percent per year in the early 1960s. Latest population figures repoint that the rate of growth has slowed to 1.33 percent annually, tantamount(predicate) to 78 million tribe a year. UNFPA 1999 The highest world population growth rate was 2.04 percent in the late 1960s. This year, it is about 1.31 percent. NY Times World population growth is equivalent to around three babies every second. UNFPA 99 New inhabitants add the equivalent of a city the size of San Francisco to world population every three daytimeThe world population is growing fast and the effects of this be &61623 pabulum shortages &61623 exhaustion of farm land and soil erosion&61623 insufficient motive supplies&6162 3 social un-rest and war &61623 immense pressure on welf ar dust and national benefits&61623 crime due to lack of space and jobs The world in the future will be able to support less not more people this is due to carefully farmed areas losing there top-soil (the cause is everywhere farming), but the world needs more and not less victuals so sizabler fields are required but these large fields allow soil and wind erosion to happen more quickly. Fertilisers only speed up this erosion e.g. America (Arizona) land is baseless and dusty because of the chemicals poisoning the land. Also in places such as Egypt where the peeing supply is irrigated from underground water supplies, the water contains mineral salts, which will behind poison the land.We can say that overpopulation can effect the jurisprudence in a dramatic way, as the ratio between a police officer and the public is increasing. This can effect the police officers productivity and speciality in dealing with crime. We can say that Public services in general are under-funded, this in part can be darned on the amount of people not paying tax (asylum seekers, unemployed, O.A.Ps). I.e. as science grows so do length of years people live as dose the funding which is required to keep these people (pension, benefits) which could be spent on Public services. The Police Federations research foundcapital of the United Kingdom has 25,121 officers, one for every 290 ... ...that any conclusion upon the safety of introducing genetically modify materials into the UK is premature, as there is insufficient evidence to inform the decision-making process at present.There are concerned that consumption of the maize will control to an increased resistance to antibiotics in human and animal populations. The testing carried out on GM foods is inadequate. Quite often the testing is carried out by the companies themselves that seek to benefit financially from the product. Releasing genetically modified organisms into the surroundings represents genetic pollution. There are long held concerns about the transfer from genetically engineered play plants to wild relatives to create superweeds, which could out-compete and disrupt the natural biodiversity of an area. Many GM crops are also able to crossbreed with neighbouring crops. Government research concluded that breed would be inevitable. Critics argue that we do not know comme il faut about the way genes operate and interact to be sure of what the resultant role of any modification will be. They worry that the alterations could accidentally lead to substances that are poisonous or trigger allergies.
