    Record melt from Greenland icesheet in 2010 - Yahoo! News

    "We’re adding 77 million energy-consuming people to the planet every year." Not one politician (including Al Gore) has talked about population growth in regards to many of our problems!


    "The global rate of human population growth peaked around 1963, but the number of people living on Earth—and sharing finite resources like water and food—has grown by more than two-thirds since then, topping out at over 6.6 billion today. Human population is expected to exceed nine billion by 2050. Environmentalists don’t dispute that many if not all of the environmental problems—from climate change to species loss to overzealous resource extraction—are either caused or exacerbated by population growth.

    “Trends such as the loss of half of the planet’s forests, the depletion of most of its major fisheries, and the alteration of its atmosphere and climate are closely related to the fact that human population expanded from mere millions in prehistoric times to over six billion today,” says Robert Engelman of Population Action International"

    The Apalachicola river is warming each and every year also. Mostly from runoff from up stream as far north as Gainesville, GEORGIA.

    Malthusian theories have already been debunked.

    How so? What people call debunking is merely pointing out the inability of Malthus to predict scientific advancements that led to greater productivity and longevity. Regardless, if the population keeps going up, the Law of Diminishing Returns would eventually take hold. His expectation of disaster coming soon may have been wrong, but his general thesis is correct. To say differently is to say that the earth should be able to sustain a limitless number of humans, which is false on the face of it.

    We have much of the world's coral reefs dead or dying. Huge fisheries have been depleted from over fishing. There are enormous dead areas on the east coast from agriculteral runoff. On the West Coast we are seeing dead areas on our coast from changes in the ocean chemistry. There are indictations of changing atmospheric circulation already affecting our agriculter.

    It is so strange to me to see people actually politicizing what should be straight forward science. Global warming and the fishery depletion worldwide are neither conservative nor liberal. They are both dangers to the futures of our children worldwide.

    Because of the wonders of modern agriculter, people like Borglund, Malthus's predictions are still in the future. But the resources of this planet are finite. We can choose a future with room for all, by choosing to limit our population, or we can choose a future that looks like Haiti. To divide that choice into Republican and Democratic Party terms is to discard the lessons of some very wonderful people such as Governor Tom McCall.
