Over 7 Billion human in the world, today. World population is expected to grow another 1 billion in just 12 years, creating unprecedented demand for food, water, energy, and employment. Population growth is expected to be most rapid in the 49 least developed countries, which will double the size from around 900 million today to 1.8 billion in 2050. There were only1 billion humans in 1804; 2 billion in 1927; 6 billion in 1999; and 7.2 billion by 2013. UN forecasts a range from 8.3 billion to 10.9 billion people by 2050, with 9.6 billion as the mid-projection.

A number of scientists have argued that the current global population expansion and accompanying increase in resource consumption threatens the world's ecosystem, as well as straining humanity's ability to feed itself. The InterAcademy Panel Statement on Population Growth, which was ratified by 58 member national academies in 1994, called the growth in human numbers "unprecedented", and stated that many environmental problems, such as rising levels of atmospheric carbon dioxide, global warming, and pollution, were aggravated by the population expansion.Indeed, some analysts claim that overpopulation's most serious impact is its effect on the environment. At the time of the 1994 IAP statement, the world population stood at 5.5 billion, and lower-bound scenarios predicted a peak of 7.8 billion by 2050, a number that current estimates state will be reached in the late 2020s.

To keep up with population and economic growth, food production should increase by 70% by 2050. Meat consumption is predicted to increase from 37 kg/ person/year in 2000 to over 52 kg/person/year by 2050; if so, then 50% of cereal production would go to animal feed. Farm processing insects for animal feed may offer a more sustainable option as"Insects are everywhere and they reproduce quickly, and they have high growth and feed conversion rates and a low environmental footprint," according to FAO. Some 2 billion people worldwide already supplement their diet with insects today.FAO’s Food Price Index as of April 2013 is about 9% lower than its peak in February 2011. However, food prices may rise again due to increasing affluence (especially in India and China), soil erosion and the loss of cropland, increasing fertilizer costs (high oil prices), market speculation, aquifer depletion, falling water tables and water pollution, diversion of crops to biofuels, increasing meat consumption, falling food reserves, diversion of water from rural to urban, and a variety of climate change impacts.


In just 38 years, the world should create enough electrical production capacity for an additional 3.3 billion people. There are 1.3 billion people (20% of the world) without electricity today, and an addition 2 billion people will be added to the world’s population between now and 2050. Compounding this is the requirement to decommission aging nuclear power plants and to replace or retrofit fossil fuel plants. About 3 billion people still rely on traditional biomass for cooking and heating. If the long-term trends toward a wealthier and more sophisticated world continue, our energy demands by 2050 could be more than expected. However, the convergences of technologies are accelerating to make energy efficiencies far greater by 2050 than most would believe possible today. So the world is in a race between making a fundamental transition fast enough to safer energy and the growing needs of an expanding and wealthier population.


The World Meteorological Organization reports that the amount of CO2 in the atmosphere reached a record levels in 2012, or 140% of the pre-industrial level of 280 parts per million. The daily average of atmospheric CO2 as measured in Hawaii surpassed 400 ppm on May 10, 2013. It was 391.03 ppm in October 2012; 388.92 ppm in October 2011; and 387.15 ppm in October 2010. According to NOAA, 2012 was the hottest year in the U.S. (coterminous 48 states) since record-keeping began in 1895, and the ninth warmest on record globally.


can provide everything of human needs..
food, energy, oxygen, water, space..
A place where more than 7 billion people lived
and still remains growing

World cant enlarge the shape to contains another 3 billion people in 2045,
world cant multiply fossil fuel to fulfill needs of increasing of car user in 2050,
world doesnt need bigger space but what it needs is "ballance"

A massive globe consist of billions of little aspects on it.
one of those, is YOU,
world cant forbid you to damage what it has
because, the impact is not for world itself,
but for US...
