Overwhelming evidence has engendered a consensus among global scientists that the human population level and trend are unsustainable. Although we are part of nature, we may have some choice in the ongoing process of which our numbers are but one variable. Individual, social, and institutional factors are examined, and policy options are considered. Evidence is given debunking the claim that the rich attempt to coerce poor nations to reduce fertility. Carrying capacity and optimum population concepts are discussed, particularly as to equilibrium potential. Prospects for pro-active success are entertained.
So what's the biggest time-bomb for Obama, America, capitalism, the world? No, not global warming. Not poverty. Not even peak oil. What is the absolute biggest, one like the trigger mechanism on a nuclear bomb, one that'll throw a wrench in global economic growth, ending capitalism, even destroying modern civilization? [...more]

Air quality in homes and offices is becoming a major health concern. Volatile organic compounds (VOCs) found in indoor air emanate from adhesives, furnishings, clothing, and solvents and have been shown to cause illnesses in people. Researchers tested ornamental indoor plants for their ability to remove harmful VOCs from indoor air. The study concluded that simply introducing common ornamental plants into indoor spaces has the potential to significantly improve the quality of indoor air.
The number of hungry people, which was declining for several decades, bottomed out in the mid-1990s at 825 million. It then climbed to 915 million in 2008 and jumped to over 1 billion in 2009. With world food prices projected to continue rising, so too will the number of hungry people, leaving millions of families trying to survive on one meal per day.
“We know from studying earlier civilizations such as the Sumerians, Mayans, and many others,” says Brown, “that more often than not it was food shortages that led to their demise. It now appears that food may be the weak link in our early twenty-first century civilization as well.
The Earth has nine biophysical thresholds beyond which it cannot be pushed without disastrous consequences, the authors of a new paper in the journal Nature report. Ominously, these scientists say, we have already moved past three of these tipping points. [...more]
Some people who are serious about wanting to reduce their "carbon footprint" on the Earth have one choice available to them that may yield a large long-term benefit - have one less child.
Debaters on population usually take two sides: either they see it as a huge problem facing humanity, or that it's a non-issue. They're both wrong.
