Is Earth About To Face An Ecological Collapse?

Earth Ecological Collapse Approaching? -- Future Pundit

A huge ecological shift headed our way in the 21st century?

Using scientific theories, toy ecosystem modeling and paleontological evidence as a crystal ball, 18 scientists, including one from Simon Fraser University, predict we're on a much worse collision course with Mother Nature than currently thought.

In Approaching a state-shift in Earth's biosphere, a paper just published in Nature, the authors, whose expertise span a multitude of disciplines, suggest our planet's ecosystems are careening towards an imminent, irreversible collapse.

China Admits Three Gorges Dam Has Problems

The Three Gorges Dam on the Yangtze River in Yichang, Hubei province is seen in this 2009 file photo. China's landmark dam project provides benefits to the Chinese people, but has created a myriad of urgent problems from the relocation of more than a million residents to risks of geological disasters, the Chinese government said on Thursday.

Controversial Three Gorges Dam Has Problems, Admits China -- Christian Science Monitor

The world's largest hydroelectric project was designed to tame the flood-prone Yangtze River and to generate clean energy. But the water is becoming polluted, and regular landslides are making life near the dam dangerous.

The Chinese government made a rare admission Thursday of something that millions of people living around the Three Gorges dam know only too well: There is a dark side to the country’s proudest engineering achievement.

'World Needs A Barometer Of Life'

From The BBC:

The world needs a "barometer of life" to prevent ecosystems and species being lost forever, scientists have warned.

Existing schemes, they said, did not include enough species from groups such as fungi and invertebrates to provide a detailed picture of what is at risk.

Writing in the journal Science, the researchers said the barometer would increase the number of species being assessed from almost 48,000 to 160,000.

The data would help identify areas in need of urgent action, they added.

All Things Bright And Beautiful: What Photographer Found In One Cubic Foot

From The Guardian:

David Liittschwager's amazing images – featured in next month's National Geographic magazine – capture Earth's ecosystems as never before.

Just how much life can you find in an ecosystem of one cubic foot? That is the question photographer David L­iittschwager set out to answer when he took a 12-inch metal frame to a range of different environments on land and in water, in tropical climes and temperate regions and began to chart the living organisms.

India's Water Use 'Unsustainable'

Much of the water used in paddy fields is pumped from underground.

From The BBC:

Parts of India are on track for severe water shortages, according to results from Nasa's gravity satellites.

The Grace mission discovered that in the country's north-west - including Delhi - the water table is falling by about 4cm (1.6 inches) per year.

Writing in the journal Nature, they say rainfall has not changed, and water use is too high, mainly for farming.

The finding is published two days after an Indian government report warning of a potential water crisis.

That report noted that access to water was one of the main factors governing the pace of development in the world's second most populous nation.

Galapagos Face Ecological Disaster Due To Tourism: Study

From Yahoo News/AFP:

LONDON, (AFP) – Mosquitoes brought into the Galapagos on tourist planes and boats threaten to wreak "ecological disaster" in the islands, central to Darwin's theory of evolution, a study said Wednesday.

The insects can spread potentially lethal diseases in the archipelago off Ecuador's Pacific coast, used by Charles Darwin as the basis of his seminal work "On the Origin of Species by Means of Natural Selection".

"Few tourists realise the irony that their trip to Galapagos may actually increase the risk of an ecological disaster," said Simon Goodman of Leeds University, one of the study's co-authors.

Containing The Sahara With Bacteria-Built Walls

From Popsci.com:

Bacteria that construct walls out of sand could save a third of the world's population from desertification

The Sahara, as well as other deserts around the world, is growing, in a process called desertification that ends up displacing people and crops. The situation has become drastic in a number of sub-Saharan countries. One suggestion from architect Magnus Larsson at the recent TED Global conference suggests constructing a massive wall, 3,700 miles long -- built from the sand itself. The trick would be to use bacterial labor to build it.

Lack Of Water Threatens "Garden of Eden"

From Earth Magazine:

Since the downfall of Saddam Hussein in 2003, Iraqis and scientists from around the world have been working hard to restore Iraq’s once-lush marshes. But after several years of measurable improvement, drought and competition over limited water supplies threaten to reverse this progress. Those working on the marshes are confident that the marshes can come back — but whether the people who rely on these wetlands for their livelihood will be as resilient remains to be seen.

Tasmanian Devils Could Be Gone in 20 Years

From Live Science:

An Australian zoologist is leading a national project to help save the endangered Tasmanian devil from extinction, a situation that could arise within the next 20 years, experts predict.

Jeremy Austin will lead the project, which has received $168,000 Australian (Australian dollars currently are about two-thirds the value of U.S. dollars) from that nation's government. The research will rely on genetic procedures to examine the impact of an infectious cancer, devil facial tumor disease, on Tasmanian devils.

Tasmanian devils became extinct on the Australian mainland about 400 years ago and are now found only on the Australian island state of Tasmania. Unlike Tasmanian tigers, devils survived initial human impacts following European colonization but in the past decade their numbers have fallen drastically.

"We have lost over half our devils in the past 10 years, with an estimated population of 20,000 to 50,000 mature devils left. Extinction within the next 20 years is a real possibility unless we find a vaccine, eradicate the disease and establish captive colonies," Austin said.

Mud Eruption 'Caused By Drilling'

(Photo from BBC News)

From The BBC News:

The eruption of the Lusi mud volcano in Indonesia was caused by drilling for oil and gas, a meeting of 74 leading geologists has concluded.

Lusi erupted in May 2006 and continues to spew out boiling mud, displacing around 30,000 people in East Java.

Drilling firm Lapindo Brantas denies a nearby well was the trigger, blaming an earthquake 280km (174 miles) away.

Around 10,000 families who have lost their homes are awaiting compensation, which could run as high as $70m (£43m).

The Possible Extinction Of North America's Freshwater Fish

Freshwater Fish In N. America In Peril, Study Says
-- Yahoo News/AP

WASHINGTON - About four out of 10 freshwater fish species in North America are in peril, according to a major study by U.S., Canadian and Mexican scientists.

And the number of subspecies of fish populations in trouble has nearly doubled since 1989, the new report says.

One biologist called it "silent extinctions" because few people notice the dramatic dwindling of certain populations deep in American lakes, rivers and streams. And while they are unaware, people are the chief cause of the problem by polluting and damming freshwater habitats, experts said.

In the first massive study of freshwater fish on the continent in 19 years, an international team of dozens of scientists looked not just at species, but at subspecies — physically distinct populations restricted to certain geographic areas. The decline is even more notable among these smaller groups.

10 Species You Can Kiss Goodbye

Sumatran Rhinoceros

From Live Science:

Think the polar bear has it bad? Here are 10 critters who are even worse off than our favorite threatened Arctic resident. Listed on the International Union for Conservation of Nature's (IUCN) Red List as critically endangered, meaning they face an extremely high risk of extinction in the immediate future, these animals may not live to see the end of the next decade without the a similar effort of human intervention that brought them to the brink in the first place.
