NO WAY: Overpopulation


FROM WIKIPEDIA:  Overpopulation

Population growth that exceeds the carrying capacity of an area or environment results in overpopulation.[21] Spikes in human population can cause problems such as pollution, water crisis,[22][23] and poverty.[24][25] World population has grown from 1.6 billion in 1900 to an estimated 7 billion today. In Mexico alone, population has grown from 13.6 million in 1900 to 107 million in 2007.[26] Virginia Abernethy notes that immigration is a road that provides a “relief valve” to overpopulation that stops a population from addressing the consequences of its overpopulation and that exports this overpopulation to another location or country.[27]

In 2000, the United Nations estimated that the world’s population was growing at the rate of 1.14% (or about 75 million people) per year. According to data from the CIA’s World Factbook, the world human population currently increases by 145 every minute.[28] The United States Census Bureau issued a revised forecast for world population that increased its projection for the year 2050 to above 9.4 billion people, up from 9.1 billion people. There are a billion more added every 12 years. Almost all growth will take place in the less developed regions.[29]

World Population to Reach 7 Billion This Year


World Population to Reach 7 Billion This Year

Throughout much of history, the global human population grew slowly, reaching 1 billion in about 1800. The world’s population has increased rapidly since that time, growing by about 4 billion in the past 50 years alone. Later this year, it is expected to cross the 7 billion mark, and according to UN projections, 10 billion people will be crowding the planet by 2100. Nearly all population growth for the next few decades is expected to be in underdeveloped regions, straining their limited resources. Meanwhile, the populations of more developed countries will remain flat, meaning there will be fewer working-age adults to support retirees living on pensions. More… Discuss
