Russian company accidentally spills 20,000 tons of oil into Arctic river
It's one of the nation's worst oil spills on record.
- The accident occurred in the Siberian city of Norilsk.
- The company said thawing permafrost caused a fuel tank to collapse.
- Thawing permafrost poses a major threat to Russia's oil industry, which is the world's third largest.
Russian President Vladimir Putin recently declared a state of emergency after an industrial accident spilled more than 20,000 tons of diesel into the Arctic environment.
The accident occurred when a fuel tank collapsed at a power plant on May 29 in the Siberian city of Norilsk, located 1,800 miles northeast of Moscow. At least 17,000 tons of diesel fuel spilled into the Ambarnaya River, turning it crimson, while another 6,000 tons leaked into the soil.
Greenpeace Russia said it's the "first accident of such a scale in the Arctic," comparing it to the Exxon Valdez oil spill off the coast of Alaska in 1989. That accident spilled 39,000 tons of fuel into the Pacific Ocean.
On Thursday, Russian officials said the leak had been contained with booms placed in the river.
"We have stopped the spread of the petroleum products," a spokesperson for the task-force in charge of the clean-up said. "They are contained in all directions, they are not going anywhere now."
Although the spill is contained, the accident likely caused long-term damage to the environment.
"The incident led to catastrophic consequences, and we will be seeing the repercussions for years to come," Sergey Verkhovets, coordinator of Arctic projects for WWF Russia, said in a statement. "We are talking about dead fish, polluted plumage of birds and poisoned animals."
Greenpeace said the clean-up won't do much good:
"The booms that were set up will only collect an insignificant part of the pollution, so we can assert that almost all of the diesel fuel will remain in the environment."
Norilsk Nickel, the owner of the power plant, said the fuel tank collapsed because of "abnormally mild temperatures" in the permafrost.

Alexei Knizhnikov, a leader with the Russian arm of the World Wildlife Fund, said that while climate change is affecting the nation's permafrost, the company could've prevented the accident if it had followed proper protocol. Russian law requires companies to install containment structures around fuel reservoirs.
"A lot of the blame lies with the company," Knizhnikov said.
During a teleconference on Wednesday, Putin criticized a Norilsk Nickel manager over the company's handling of the accident.
“I think decontamination will cost Nornickel billions of roubles, but I’m speaking not as a businessman, but as a h… https://t.co/DpArnia48m— Nornickel (@Nornickel)1591366244.0
"Why did government agencies find out about this only after two days?" Putin asked. "Are we going to find out about emergencies from social media now?"
Norilsk Nickel president Vladimir Potanin said the company would pay the costs of cleaning up the skill, estimated to be $146 million. At least one worker at the power plant has so far been arrested. He's charged with violating environmental regulations and faces up to five years in prison.
How climate change threatens Russian oil
Russia, the world's fourth-largest emitter of greenhouse gases, is especially vulnerable to the effects of climate change. The nation is warming two and a half times faster than the rest of the planet, and in recent years it's suffered costly floods and wildfires.
Thawing permafrost in Siberian regions poses a major threat to Russia's oil industry, which is the world's third largest. One key reason, as evidenced by last week's accident, is that melting permafrost jeopardizes the structural integrity of oil-field infrastructure.
Of course, when oil infrastructure is jeopardized, so is the environment. That's why Greenpeace Russia is calling for increased environmental regulations and unscheduled audits of oil producers in the nation's Arctic region.
"Environmental control should be strengthened, and the operation of facilities should be under special control to prevent accidents, especially in the conditions of melting permafrost due to global climate change," the organization said in a statement.

A new study finds that dogs fed fresh human-grade food don't need to eat—or do their business—as much.
- Most dogs eat a diet that's primarily kibble.
- When fed a fresh-food diet, however, they don't need to consume as much.
- Dogs on fresh-food diets have healthier gut biomes.

Swanson</a> of U of I's Department of Animal Sciences and the Division of Nutritional Sciences, was a bit surprised at how much better dogs did on people food than even refrigerated dog chow. "Based on past research we've conducted I'm not surprised with the results when feeding human-grade compared to an extruded dry diet," he <a href="https://aces.illinois.edu/news/feed-fido-fresh-human-grade-dog-food-scoop-less-poop" target="_blank">says</a>, adding, "However, I did not expect to see how well the human-grade fresh food performed, even compared to a fresh commercial processed brand."</p>

This resulted in their producing 1.5 to 2.9 times the amount of poop produced by dogs on the fresh diets.</p><p>Says Swanson, "This is consistent with a 2019 National Institute of Health study in humans that found people eating a fresh whole food diet consumed on average 500 less calories per day, and reported being more satisfied, than people eating a more processed diet."</p><p>Maybe even more interesting was the effect of fresh food on the gut biome. Though there remains much we don't yet know about microbiota, it was nonetheless the case that the microbial communities found in fresh-food poo was different.</p><p>"Because a healthy gut means a healthy mutt," says Swanson, "fecal microbial and metabolite profiles are important readouts of diet assessment. As we have shown in <a href="https://academic.oup.com/jas/article/92/9/3781/4702209#110855647" target="_blank">previous studies</a>, the fecal microbial communities of healthy dogs fed fresh diets were different than those fed kibble. These unique microbial profiles were likely due to differences in diet processing, ingredient source, and the concentration and type of dietary fibers, proteins, and fats that are known to influence what is digested by the dog and what reaches the colon for fermentation."</p>
How did kibble take over canine diets?<p>Historically, dogs ate scraps left over by humans. It has only been <a href="https://www.thefarmersdog.com/digest/the-history-of-commercial-pet-food-a-great-american-marketing-story/" target="_blank">since 1870</a>, with the arrival of the luxe Spratt's Meat Fibrine Dog Cakes—made from "the dried unsalted gelatinous parts of Prairie Beef", mmm—that commercial dog food began to take hold. Dog bone-shaped biscuits first appeared in 1907. Ken-L Ration dates from 1922. Kibble was first extruded in 1956. Pet food had become a great way to turn <a href="https://www.dogfoodadvisor.com/choosing-dog-food/animal-by-products/" target="_blank">human-food waste</a> into profit.</p><p>Commercial dog food became the norm for most household canines only after a massive marketing campaign led by a group of dog-food industry lobbyists called the Pet Food Institute in 1964. Over time, for most households, dog food was what dogs ate — what else? Human food? These days more than half of U.S. dogs are <a href="https://www.nytimes.com/2014/08/03/magazine/who-made-that-dog-biscuit.html" target="_blank">overweight or obese</a>, and certainly their diet is a factor.<span></span></p><p>We're not so special among animals after all. If something's healthy for us to eat—we're <em>not</em> looking at you, chocolate—maybe we should remember to share with our canine compatriots. Not from the table, though.</p>
What makes some people more likely to shiver than others?
Some people just aren't bothered by the cold, no matter how low the temperature dips. And the reason for this may be in a person's genes.
Eating veggies is good for you. Now we can stop debating how much we should eat.
- A massive new study confirms that five servings of fruit and veggies a day can lower the risk of death.
- The maximum benefit is found at two servings of fruit and three of veggies—anything more offers no extra benefit according to the researchers.
- Not all fruits and veggies are equal. Leafy greens are better for you than starchy corn and potatoes.
