POPULATION AND RESOURCE CONFLICTS – From Chapter 6. Early Signs of Decline
Lester R. Brown, Plan B 2.0: Rescuing a Planet Under Stress and a Civilization in Trouble
Pag.110

As land and water become scarce, we can expect competition for these vital resources to intensify within societies, particularly between the wealthy and those who are poor and dispossessed. The shrinkage of life-supporting resources per person that comes with population growth is threatening to drop the living standards of millions of people below the survival level. This could lead to unmanageable social tensions that will translate into broad-based conflicts.

More and better waste management at public expense is giving unlimited license to proliferate discards. Today these systems collect 3.4 pounds of product waste a day for each American man, woman, and child—twice as much as in 1960 and ten times as much as 100 years ago. It is time to revamp the system so that it no longer supports the throwaway habit.

HEALTH CHALLENGE GROWING – From Chapter 6. Early Signs of Decline
Lester R. Brown, Plan B 2.0: Rescuing a Planet Under Stress and a Civilization in Trouble
Pag.105

The HIV epidemic in Africa is now a development problem, a matter of whether a society can continue to function as needed to support its people. It is a food security problem. It is a national security problem. It is an educational system problem. And it is a foreign investment problem. Stephen Lewis, the U.N. Special Envoy for HIV/AIDS in Africa, says that the epidemic can be curbed and the infection trends can be reversed, but it will take help from the international community. The failure to fully fund the Global Fund to Fight AIDS, Tuberculosis and Malaria, he says, is “mass murder” by complacency.

DISAPPEARING PLANTS AND ANIMALS – From Chapter 5. Natural Systems Under Stress
Lester R. Brown, Plan B 2.0: Rescuing a Planet Under Stress and a Civilization in Trouble
Pag.95

Species of all kinds are threatened by habitat destruction, principally through the loss of tropical rainforests. As we burn off the Amazon rainforest, we are in effect burning one of the great repositories of genetic information. Our descendents may one day view the wholesale burning of this genetic library much as we view the burning of the library in Alexandria in 48 bc.

In the new world we are entering, protecting the diversity of life on earth is no longer simply a matter of setting aside tracts of land, fencing them, and calling them parks and preserves. Success in this effort depends on stabilizing both climate and population.
On the plus side, we now have more information on the state of the earth and the life on it than ever before. While knowledge is not a substitute for action, it is a prerequisite for saving the earth’s natural systems—and the civilization that they support.

COLLAPSING FISHERIES – From Chapter 5. Natural Systems Under Stress
Lester R. Brown, Plan B 2.0: Rescuing a Planet Under Stress and a Civilization in Trouble
Pag.91

After World War II, accelerating population growth and steadily rising incomes drove the demand for seafood upward at a record pace. At the same time, advances in fishing technologies, including huge refrigerated processing ships that enabled trawlers to exploit distant oceans, enabled fishers to respond to the growing world demand.

In response, the oceanic fish catch climbed from 19 million tons in 1950 to its historic high of 93 million tons in 1997. This fivefold growth—more than double that of population during this period—raised the wild seafood supply per person worldwide from 7 kilograms in 1950 to a peak of 17 kilograms in 1988. Since then, it has fallen to 14 kilograms.

On April 18, 2001, the western United States—from the Arizona border north to Canada—was blanketed with dust. It came from a huge dust storm that originated in northwestern China and Mongolia on April 5. Measuring 1,800 kilometers across when it left China, the storm carried millions of tons of topsoil, a vital resource that will take centuries to replace through natural processes

…insurance companies and reinsurance companies find it difficult to calculate a safe level of premiums, since the historical record traditionally used to calculate insurance fees is no longer a guide to the future. For example, the number of major flood disasters worldwide has grown during each of the last several decades, increasing from 6 major floods in the 1950s and 1960s to 8 in the 1970s, 18 in the 1980s, and 26 in the 1990s

Western Europe, traditionally experiencing a heavily damaging winter storm perhaps once in a century, had its first winter storm to exceed $1 billion in 1987—one that wreaked $3.7 billion in destruction, $3.1 billion of which was covered by insurance. Since then, it has had eight winter storms with insured losses ranging from $1.3 billion to $5.9 billion

Reduced snow pack to feed the Yellow River flow will shrink China’s wheat harvest, the largest in the world. Alterations in the flow of the Yangtze River will directly affect China’s rice harvest—also the world’s largest. And India’s wheat harvest, second only to China’s, will be affected by the flows of both the Indus and the Ganges. Anything that lowers the summer flow of the Mekong will affect the rice harvest of Viet Nam, a leading exporter.

At a practical level, the IPCC projected rise in temperature is a global average. In reality, the rise will be very uneven. It will be much greater over land than over oceans, in the higher latitudes than over the equator, and in the continental interiors than in coastal regions.

When the Industrial Revolution began, the atmospheric CO 2 level was roughly 270 ppm. The 377 ppm registered for 2004 is not only far above any level over the last 740,000 years, it may be nearing a level not seen for 55 million years. At that time the earth was a tropical planet. There was no polar ice; sea level was 80 meters (260 feet) higher than it is today
