The study, by 1,360 experts in 95 nations, said a rising human population had polluted or over-exploited two-thirds of the ecological systems on which life depends, ranging from clean air to fresh water, in the past 50 years.

"At the heart of this assessment is a stark warning," said the 45-member board of the Millennium Ecosystem Assessment.

"Human activity is putting such strain on the natural functions of Earth that the ability of the planet's ecosystems to sustain future generations can no longer be taken for granted," it said.

Ten to 30 percent of mammal, bird and amphibian species were already threatened with extinction, according to the assessment, the biggest review of the planet's life support systems.

"Over the past 50 years, humans have changed ecosystems more rapidly and extensively than in any comparable time in human history, largely to meet rapidly growing demands for food, fresh water, timber, fiber and fuel," the report said.

"This has resulted in a substantial and largely irreversible loss in the diversity of life on earth," it added. More land was changed to cropland since 1945, for instance, than in the 18th and 19th centuries combined.

GETTING WORSE

"The harmful consequences of this degradation could grow significantly worse in the next 50 years," it said. The report was compiled by experts, including from U.N. agencies and international scientific and development organizations.

U.N. Secretary-General Kofi Annan said the study "shows how human activities are causing environmental damage on a massive scale throughout the world, and how biodiversity -- the very basis for life on earth -- is declining at an alarming rate."

IMHO, this is not going to get any better. I have seen nothing to show evidence that we are pushing alternate fuel sources the way we should be, and the population is going to soon spiral out of control (far beyond what the problem is at now).

I'm afraid that the next global killer won't be an asteroid, or a series of massive earthquakes, but a series of global diseases.



Future changes could bring sudden outbreaks of disease. Warming of the Great Lakes in Africa due to climate change, for instance, could create conditions for a spread of cholera.


The earth is similiar to the human body in that in humans, one of the first indicators of disease is the signs that appear on the surface ofour skin. Well, the earth's surface has bee giving us these signs for years now and we just keep letting these things go unchecked.
