ZGP July 1999 World population produce peaked at virtually two percent per year in the early 1960s. Latest population figures indicate that the rate of growth has slowed to 1.33 percent annually, resembling to 78 million great deal a year. UNFPA 1999 The highest world population growth rate was 2.04 percent in the late 1960s. This year, it is ab come forward 1.31 percent. NY Times World population growth is equivalent to around collar babies every second. UNFPA 99 New inhabitants add the equivalent of a city the size of San Francisco to world population every three dayThe world population is growing fast and the effects of this atomic number 18 &61623 food shortages &61623 exhaustion of farm discharge and soil erosion&61623 skimpy power supplies&61623 social un-rest and war &61623 immense pres genuine on welfare system and national benefits&61623 crime due to lack of space and jobs The world in the future depart be able to support little(prenominal) NOT more deal this is due to carefully farmed areas losing there top-soil (the crusade is over farming), but the world needs more and not less food so larger fields are required but these large fields allow soil and wind erosion to hazard more quickly. Fertilisers only speed up this erosion e.g. America (Arizona) land is useless and dusty because of the chemicals poisoning the land. Also in places such as Egypt where the water supply is irrigated from underground water supplies, the water contains mineral salts, which allow for slowly poison the land.We can say that overpopulation can effect the law of nature in a dramatic way, as the ratio between a police officer and the public is increasing. This can effect the police officers productivity and effectiveness in dealing with crime. We can say that Public serve in general are under-funded, this in part can be blamed on the amount of people not paying measure (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 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 environment represents genetic pollution. There are long held concerns about the transfer from genetically engineered crop 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 reason out that crossbreeding would be inevitable. Critics argue that we do not manage enough about the way genes operate and interact to be sure of what the outcome of any modification will be. They worry that the alterations could accidentally lead to substances that are poisonous or trigger allergies.
