news: It’s a Vast World After All


It’s a Vast World After All

The world’s population currently stands at 7.2 billion and is projected to rise to between 9.6 and 12.3 billion by the end of this century. Earlier estimates had forecast a leveling off of world population around 2050, but higher-than-expected birth rates in sub-Saharan Africa mean the number of people on the planet will likely continue to rise instead. In Africa alone, the population is expected to rise from the current 1 billion to between 3.5 and 5.1 billion by 2100. More… Discuss

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]

Obesity Weighs Heavily on World


Obesity Weighs Heavily on World

The burden of obesity has grown considerably in recent decades, with about 30 percent of the global population—a whopping 2.1 billion people—now overweight or obese. Over the past 33 years, obesity rates soared 28 percent in adults and 47 percent in children, and the number of overweight and obese people more than doubled. For now, the US retains the unenviable distinction of hosting the largest portion of the world’s obese—13 percent. Though obesity was once limited to rich nations, more than two-thirds of the world’s obese now live in developing countries. In the Middle East and North Africa, more than half of adult men and nearly two-thirds of adult women are overweight or obese. More… Discuss

WATER POLITICS


Water Politics

According to the World Health Organization, each person requires about 5 gallons (20 liters) of water per day to adequately meet drinking and hygiene needs. Yet billions live without sufficient water resources. The Middle East, for instance, shares about 1 percent of the world’s available water among 5 percent of the world’s population, and its major rivers cross international borders. Such discrepancies can lead to conflict. Which Middle Eastern conflicts have been fueled by water politics? More… Discuss

 

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
