never heard of that statistic, but let's assume it's true.
What's the problem? Plenty of them... We're straining the planet's resources, in large part due to over-population. Exponentially rising population + depleting resources means trouble. It's the same problem Yeast and other simple organisms typically run into. Population growth can't go on forever, neither can economic growth.
What allows so many people to exist is mostly our technology which allows us to access plentiful energy, especially fossil fuels. If you noticed, before the economic crisis hit energy was getting more and more expensive, which will probably also happen when the economy starts to recover. It could even stop the economy from ever recovering to the levels we've seen in the past few years.
This will especially be a problem if investment in renewable energy (and even non-renewable energy) isn't taken seriously during the recession.
Yeast doesn't have the capacity to organize augment it's production method for obtain food beyond the natural environment allows.
From irrigation, to nitrogen-based fertalizers, genetics, hormones and mechanization, the food supply is ample to feed the whole human population; the problem is cost and transportation (within borders). Most hunger is caused by war.
If you go to http://www.wfp.org/country_brief/index_region.asp and look where the world food program work almost all of those are engaged in some type of long term conflict or are under the control of a corrupt or weak government.
Rising energy costs are a sign of more people using energy, which means more people have modern heating and lighting. India still has almost half a billion people with out electricity but it less than 10 years ago.
Often as countries develop they leap frog the steps industrialized nations had to take, saving money and impacting the environment less. Cell phones, computerized banking, credit cards, and renewable energy allow rapid change without the large industrial infrastructure investment with out massive temporary employment that displaced major portions of the population in the US.
Don't confuse fossil fuels with fuel. Brasil has built its economy on biodiesel. Small remote villages are installing solar panels, The US and Canada depend on an almost unlimited source of coal and natural gas for electricity. The minute we have a viable portable unlimited fuel for transportation, the problem is solved. The world enters a new age of movement. Renewable resources are coming; profitability ensures this.
I don't understand how anybody can look at the progress in India, China, or Vietnam and think things are getting worse.
Now, don't take this to mean that I think there are no problems, there is a long way to go but progress is being made.
I would cite regulation, but I know you will simply ignore it.
