Sustainability: How Wolves Change Rivers - Video


Visit Sustainableman.org/ to explore the world of sustainability.

For more from George Monbiot, visit monbiot.com and for more on "rewilding" and/or check out George Monbiot's book Feral: rewilding the land, the sea and human life.

NOTE: The "deer" the narrator refers to are in fact "elk," one of the largest of the deer family. The scientific report that this video is based on refers to elk so we wanted to be accurate with the truth of the story.

"When we try to pick out anything by itself, we find it hitched to everything else in the Universe." - John Muir (English naturalist)

When wolves were reintroduced to Yellowstone National Park in the United States after being absent nearly 70 years, the most remarkable "trophic cascade" occurred.

What is a trophic cascade and how exactly do wolves change rivers? George Monbiot explains in this movie remix.

In Southeast Asia, the island of Borneo is home to one of the world’s most diverse rainforests, but its natural resources are under threat.

Information from satellites is being used to evaluate the impact of the island’s future development.

The mountainous island is the third largest in the world.

It is an area of exceptional biological diversity and its natural resources have tremendous social and economic value at local, national and global levels.

While still of great importance, these resources have diminished in recent years due to logging, plantation development, mining and forest fires.

“The ecosystems in the heart of Borneo provide many local, regional and global services and benefits,” said Anna van Paddenburg, Sustainable Financing and Policy Strategy Leader for the World Wildlife Fund (WWF) Indonesia.

“The mountainous forests form the headwaters of most of Borneo’s 20 major rivers, providing water for agriculture, human consumption, and industry. 

“The forests provide timber and non-timber forest products, and store huge amounts of carbon.

“The diverse ecosystems support endemic plants and animals, which supports eco-tourism and pharmaceutical research.”

While it is widely recognised that healthy ecosystems provide services that play a critical role in maintaining individual and societal welfare, the benefits that flow from them are not always accounted for in government and private sector decision-making.

In an effort to protect the environment and develop the area in a sustainable way, the Heart of Borneo conservation agreement was initiated by WWF and signed by the governments of Indonesia, Malaysia and Brunei in 2007.

In December 2010, WWF initiated an assessment of Borneo’s natural capital to quantify and understand the value of ecosystem services and benefits.

ESA provided technical assistance through Hatfield Consultants, a Canadian environmental and geomatics consulting company that has been working in Indonesia for 20 years, and NEO BV, a value-adding data provider.

ESA Astronaut and Earth Hour: The 2012 Official Video - YouTube



This Earth Hour 2012: 8.30pm, Saturday 31 March, celebrate your action for the planet with the people of world by switching off your lights for an hour, then go beyond the hour.

André Kuipers takes Earth Hour into orbit
For the first time, Earth Hour will extend to the International Space Station, where ESA astronaut and WWF ambassador André Kuipers will keep watch over our planet as the lights switch off on 31 March, sharing photos and live commentary of his experience.

Since inception in the city of Sydney, Australia, in 2007, Earth Hour has become the world's largest voluntary action highlighting climate change and the need for sustainability.

In 2011, 5251 cities took part, reaching 1.8 billion people in 135 countries across all seven continents.

This year, Earth Hour will take place at 20:30–21:30, at participants' local time, on Saturday, 31 March, and the event will be observed from space by ESA Astronaut André on the International Space Station.

Giant Red Crabs invade the Antartic Abyss



Huge crabs more than a metre across have invaded the Antarctic abyss, wiped out the local wildlife and now threaten to ruin ecosystems that have evolved over 14 million years.

Three years ago, researchers predicted that as the deep waters of the Southern Ocean warmed, king crabs would invade Antarctica within 100 years.

But video taken by a remotely operated submersible shows that more than a million Neolithodes yaldwyni have already colonised Palmer Deep, a basin that forms a hollow in the Antarctic Peninsula continental shelf.

They are laying waste to the landscape. Video footage taken by the submersible shows how the crabs prod, probe, gash and puncture delicate sediments with the tips of their long legs.

"This is likely to alter sediment processes, such as the rate at which organic matter is buried, which will affect the diversity of animal communities living in the sediments," says Craig Smith of the University of Hawaii at Manoa, whose team discovered the scarlet invaders.

Hungry invaders

The crabs also appear to have a voracious appetite. Echinoderms – sea urchins, sea lilies, sea cucumbers, starfish and brittle stars – have vanished from occupied areas, and the number of species in colonised areas is just a quarter of that in areas that have escaped the invasion.

"[Echinoderms] constitute a significant proportion of the large animals on the seafloor in many Antarctic shelf habitats," says Smith.

The crabs come from further north and moved in as Antarctic waters have warmed, probably swept into Palmer Deep as larvae in warm ocean currents. 

They now occupy the deepest regions of Palmer Deep, between 1400 and 950 metres. In 1982, the minimum temperature there was 1.2 °C – too cold for king crabs – but by last year it had risen to a balmier 1.47 °C.

Melting ice sheets tend to make shallower waters in Antarctica cooler than deeper ones. There were no king crabs at depths of 850 metres or less, suggesting that these waters are still too cold for them. But with waters warming so rapidly, they could spread to regions as shallow as 400 metres within as little as 20 years, says Smith.

NASA - The Osprey Has Landed

At NASA's Kennedy Space Center in Florida, an adult osprey guards its young in a nest built on a platform in the Press Site parking lot.

In the background is the 12,300-square-foot NASA logo painted on the side of the Vehicle Assembly Building (VAB).

 The VAB and Press Site are located at the Turn Basin in Launch Complex 39, making it an ideal osprey nesting place.

The Merritt Island National Wildlife Refuge overlaps with Kennedy Space Center property and provides a habitat for many types of wildlife, including the osprey, and 330 species of birds. For information on the refuge, visit http://www.fws.gov/merrittisland/Index.

New Carnivore found in Madagascar

A photo issued by the Durrell Wildlife Conservation Trust of Durrell's vontsira (Salanoia durrelli), a new species of carnivore which has been discovered in Madagascar.

The cat-sized, speckled brown mammal belongs to a family of mongoose-like animals found only on the island nation and is probably one of the most threatened carnivores in the world, researchers said

Ready for Liftoff - Ospreys at Nasa

Ready for Liftoff

A family of Osprey are seen outside the NASA Kennedy Space Center Vehicle Assembly Building in Cape Canaveral, Fla. on Thursday, May 13, 2010.

The Merritt Island National Wildlife Refuge overlaps Kennedy and provides a habitat for 330 species of birds, including the osprey.

A variety of other wildlife--117 kinds of fish, 65 types of amphibians and reptiles, 31 different mammals, and 1,045 species of plants--also inhabit the refuge.

The countdown is on for today's scheduled launch of space shuttle Atlantis on its STS-132 mission. At NASA's Kennedy Space Center in Florida, technicians at Launch Pad 39A continue preparations for the liftoff at 2:20 p.m. EDT.

Borneo mega-dams proposal raises fears for tribes, wildlife

A massive tract of Borneo jungle, an area the size of Singapore, will soon disappear under the waters of the Bakun dam, a multi-billion-dollar project nearing completion after years of controversy.

The dam, which forced thousands of indigenous people off their ancestral lands, has struggled through setbacks and delays since its approval in 1993, as well as fierce criticism over its environmental impact.

But even before the turbines of the 2.2 billion dollar hydro-electric facility begin to turn, activists have sounded the alarm over plans for 12 more mega-dams on Malaysia's half of Borneo which it shares with Indonesia.

Balan Balang, an elderly chief of the Penan tribe, sighs as he talks of the Murum dam, the first of the dozen dams envisioned for Sarawak state, which will drown the hunting grounds and burial sites of his people.

"This government is very bad. In the old days people would fight us using machetes or spears. But now they just sign away our lives on pieces of paper," said the headman, who sports the elongated earlobes distinctive to his tribe.

"My people never want to leave our place. We want to die in our place," he said, after a long journey from his rainforest home to seek help from indigenous lawyers in Miri, a coastal town in Malaysian Borneo.

Human rights activists are intent on avoiding a repeat of the botched relocation of some 15,000 indigenous people in the Bakun area who they say have made an unhappy transition to life in resettlement areas.

Balan Balang's village is outside the Murum resettlement area, but some 1,500 people -- mostly Penan but including another of Sarawak's tribes, the Kenyah -- will be forced to abandon their homes for an uncertain future.

The chief, who is not sure of his birth date but reckons he is "between 70 and 80 years old", has seen much hardship during his long life.

As a young boy he watched fearfully as Japanese warplanes flew overhead during the World War II occupation, while rampant logging later degraded the jungles where his people forage for food, wild game, and materials for shelter.

"Now the rivers are all polluted. The wildlife has slowly disappeared -- wild boar, deer, gibbons. Even the broad-leafed plants that we use for roofing, and rattan which we use to make mats and baskets, is gone," he said.

But what brought him to Miri are new threats to his way of life, the dam project as well as plantation firms who want to clear what is left of the jungle and grow palm oil and foreign timber species.

"Our people oppose our area being included for the dam because that's where we come from, our ancestors lived and died and were buried there. For us we have no other place, that is our only place," he said.
