The oil sands industry is in the throes of a major expansion, powered by C$20 billion ($19 billion) a year in investments. Companies including Syncrude Canada Ltd., Royal Dutch Shell Plc and Exxon Mobil Corp. affiliate Imperial Oil Ltd. are running out of room to store the contaminated water that is a byproduct of the process used to turn bitumen — a highly viscous form of petroleum — into diesel and other fuels.
By 2022 they will be producing so much of the stuff that a month’s output of wastewater could turn an area the size of New York’s Central Park into a toxic reservoir 11 feet (3.4 meters) deep, according to the Pembina Institute, a nonprofit in Calgary that promotes sustainable energy.
To tackle the problem, energy companies have drawn up plans that would transform northern Alberta into the largest man-made lake district on Earth. Several firms have obtained permission from provincial authorities to flood abandoned tar sand mines with a mix of tailings and fresh water.
One big concern surrounding end-pit lakes is that the contaminated water will spread through the boreal ecosystem, the tract of trees and marshland that stretches around the top of the world from Canada to Russia and Scandinavia. Boreal forests store almost twice as much carbon as tropical forests.
Climate Change Shifts Bird Migration—One Generation at a Time
Biologists unravel how warming weather causes some birds to migrate earlier.
In the last few decades birders and biologists alike have noticed that spring migration is changing. Species are arriving on their breeding grounds earlier each year. It’s clear there’s a link between climate change and shifting travel dates, but a new study reveals that individual black-tailed godwits are very consistent in their migratory timing, challenging assumptions about how warmer weather shifts behavior.
These leggy, reddish shorebirds winter in Spain and Portugal. They return to their Icelandic breeding grounds each spring, between mid-May and mid-April, often nesting a month after arrival. A team of biologists who closely track their movements have noted that the birds arrive two weeks earlier today than they did twenty years ago.
To figure out why, they first tackled the long-held assumption that balmier weather might trigger individual birds to take flight sooner each season. Poring over 14 years of records for 54 individual godwits, they discovered something curious: Each bird returned year after year on roughly the same day.What did change was the birds’ nesting date.

Six tons of elephant ivory crushed to dust by the U.S. Fish and Wildlife Service. A must see.
This video shows how small frogs and other animals use the FrogLog to escape from swimming pools. The FrogLog provides an escape ramp for lizards, chipmunks, squirrels, mice, birds, bats, ducklings, and other small animals.
I need to make something similar for my parents’ pool!
No. This should be retitled:”How the Dutch killed nearly every animal in their country with clever engineering”
soon-to-be official ban on ALL wild animals in circuses
Just the UK, not the EU…
Pulitzer Center grantee Jim Wickens obtained footage proving that fishermen in South America are illegally hunting dolphins to use their meat as bait for sharks. Some environmentalists believe three thousand or more of the animals are slaughtered every year.
Both horrible and heartening. Horrible because dolphins are sentient and social beings; heartening because investigative journalism is alive and well.
Thanks to a former NBA star, a coalition of Chinese business leaders, celebrities and students, and some unlikely investigative journalism, eating shark fin soup is no longer fashionable here. But what really tipped the balance was a government campaign against extravagance that has seen the soup banned from official banquets.
“People said it was impossible to change China, but the evidence we are now getting says consumption of shark fin soup in China is down by 50 to 70 percent in the last two years,” said Peter Knights, executive director of WildAid, a San Francisco-based group that has promoted awareness about the shark trade. The drop is also reflected in government and industry statistics.
“It is a myth that people in Asia don’t care about wildlife,” Knights said. “Consumption is based on ignorance rather than malice. ”
The dramatic expansion in China’s middle and upper classes has transformed the country into a major driver of global wildlife trafficking. The Obama administration is so concerned about Chinese demand for endangered wildlife that it made the subject an important part of its bilateral dialogue this year.
More than 70 million sharks were killed last year, largely to satisfy rapacious demand from China’s newly rich for shark fin soup.
Lavish spending by China’s wealthy has also sent demand for ivory skyrocketing, fueling a massive expansion in elephant poaching in Africa.
The consequences of the traffic go beyond a crisis for wildlife. The illegal ivory trade has financed global crime networks and local insurgents, including Somalia’s al-Shabab — responsible for last month’s attack on a Nairobi shopping mall.
“Conservation is more about China now than it is about Africa,” said Knights. “China can be the savior of wildlife or it can be the demise of it.”
Cliffhanger by: Jean-Francois Largot - Masai Mara game reserve, Kenya
Clinging on for dear life to the side of a vertical cliff, the tiny lion cub cries out pitifully for help. His mother arrives at the edge of the precipice with three other lionesses and a male. The females start to clamber down together but turn back daunted by the sheer drop.
Eventually one single factor determines which of them will risk her life to save the youngster – motherly love. Slowly, agonisingly, the big cat edges her way down towards her terrified son, using her powerful claws to grip the crumbling cliff side.
One slip from her and both animals could end up dead at the bottom of the ravine. Just as the exhausted cub seems about to fall, his mother circles beneath him and he is snatched up in her jaws. She then begins the equally perilous journey back to the top. Minutes later, they arrive and she gives the frightened creature a consoling lick on the head. by: Paul Thompson
Often hailed as the Nobel Prize of food, the World Food Prize has received as much attention this week for its ties to industrial agriculture and genetically modified (GM) crops as it has for honoring those who feed the world’s poor.The prize has been a lightning rod for international criticism since June, when it announced as one of its laureates Robert Fraley, an executive at the biotech corporation Monsanto, which has been at the center of a number of controversies over GM crops.Fraley shared the honor with Syngenta scientist Mary-Bell Chilton and Plant Genetic Systems co-founder Marc Van Montagu, fellow pioneers in the development of high-yield GM crops resistant to disease, pests and harsh climates.
I’m not into the tone of this article, but thought y’all would appreciate knowing about it.
A number of factors all happened simultaneously to create a situation of very high energy needs and high stress in cattle and other livestock. Any one of the following factors could have an impact by itself, but when all combined, it was simply too much for the animals and they most likely succumbed to hypothermia.
The contributing factors included:
- Animals were not adapted to winter conditions. Cattle will grow a thicker hair coat in response to shorter days, and cooler temperatures. But temperatures prior to the storm were in the 70°’s. For cattle, this meant they had thin hair coats and little protection from the elements.
- Snow was preceded by hours of rain. A wet hair coat reduces the “insulation” that the hair and hide provide and increases the rate of heat loss from the body. For example, a cow with a wet hair or summer hair coat has critical temperature of 59°, while one with a dry, heavy winter coat has a critical temperature of 18°. The critical temperature is the temperature at which the animal must increase its metabolism, or burn its own energy, to maintain its body temperature. The further the effective temperature is below the critical temperature, the more energy the animal must use to maintain its body temperature. See “Spring Storms and Cold Stress” for more detailed information.
- Winds in this blizzard were recorded up to 60 mph. Both research and practical experience show what a difference “wind chill” has on effective temperature. The range and pastures that are grazed during summer months are typically “open” – without constructed windbreaks, and usually very few natural windbreaks. With the storm so early in the year, most livestock were still out on summer range and pastures. Thus, animals felt the full intensity of the wind.
- The hair coat, temperature, moisture and wind combination meant the animals’ energy needs to maintain body temperature were much higher than even during a “normal” winter blizzard.
- Coupled with the very high energy needs of the animals was the fact that most of the feed the cattle were currently eating was quite low in energy. Cattle grazing lush green grass makes a beautiful picture, but the reality is that lush, rapidly growing green grass is very high in moisture and low in energy per pound of feed consumed. The unusually large rainfall in September had created this rapidly growing grass in many areas. Under normal weather conditions, cattle were able to consume large quantities of grass to meet and even exceed their energy needs. But under blizzard conditions, it was not possible for them to consume adequate amounts of forage to meet their much higher than normal energy needs.
- To try to escape or reduce the harsh wind, cattle will walk with the wind and seek areas of shelter, such as draws and ravines. Walking through heavy, wet and deep snow increased their energy needs even more. The severity of the snow fall also meant that the animals were walking blind, and could easily fall in to gullies, walk into a stock dam or creek, or gather into a fence corner and face crushing and trampling.
With all the factors above combining effects, exhaustion and the inability to maintain their own body temperature finally caused cattle to simply stop and succumb to hypothermia.
