The efforts of the government to regulate Big Fishing and all its known and unknown evils often have the adverse effect of undercutting people for whom the ocean is something more than mere industry. The realities on the docks aren’t always as legislators understand them, says this first installment of the Medium‘s  inaugural episode of Food Crimes: The Hunt For Illegal Seafood.

The United States imported as much as 90 percent of its fish in 2013, up from 54 percent in 1995, according to the National Oceanic and Atmospheric Administration (NOAA). In fact, the United States has tripled the dollar amount of fish it imports, to more than 5 billion pounds of fish worth $18 billion. Couple these figures with the staggering estimate that between one quarter and one third of all fish sold in the United States is illegal, and you’re an equation or so away from going vegan.

What can one man do towards protecting the wild? For starters, your efforts could center around saving Africa’s last remaining wetland wilderness. Then, you could be so relentless in your mission that UNESCO includes your ‘battleground’ in its World Heritage List. Then, you keep at your preservation project until you meet the Minister of Environment and get him to sign a pact on protecting the river system. If that all sounds good to you, allow us to introduce explorer Steve Boyes who has done all of the above and pledged his life to the conservation of the Okavango River Delta.

Located in northern Botswana, this untouched 18,000 square kilometer alluvial fan is the largest of its kind, and is supplied by the world’s largest undeveloped river catchment — the mighty Kavango Basin. The Okavango Delta is home to the largest-remaining elephant population and keystone populations of lion, hyena, giraffe and lechwe antelopes. It’s the size of Texas, and visible from space.

Rail or road – what is the best mode of transport for free flow of goods from Brazil to China? PHOTO: Andrew Snyder

China recently announced plans to build a 5,300 km railway linking the Atlantic with the Pacific, cutting through the heart of the Amazon jungle in Brazil and Peru. Environmental groups are concerned that the railway will threaten sensitive ecosystems, wildlife and indigenous peoples. Indeed on the face of it, this would be a disaster for conservation in the most biologically rich place on Earth. But is a train line in fact the lesser of two evils?

Roads bring access to previously remote areas – and consequently bring down a cascade of problems on tropical forests. Logging, mining, and hunting result in the destruction of forests, all paving the way for their complete conversion to agriculture. Indeed, in the Amazon 95% of deforestation occurs within 5km of a road. Train lines on the other hand are usually state-controlled and more easily regulated. The proposed line will cost an estimated US$10 billion to build and will reduce the cost of shipping oil, iron ore, soya, beef and other commodities from Brazil and Peru to Asian markets.

Sri Lanka Takes the Ecofeminism Route

The new national scheme aims to set up 1,500 community groups around Sri Lanka's 48 lagoons, which will offer alternative job training and micro-loans to 15,000 people. The groups will be responsible for the upkeep of designated mangrove forests.

Big news for the environment: Sri Lanka’s new government just took the unprecedented, historic step to protect all of its mangroves. The move, the first of its kind anywhere in the world, will provide long-term environmental, social and, last but not least, economic benefits to the Indian Ocean island nation, and provide a model for other vulnerable tropical nations to follow. Whose are the champions of this mission? Women.

Started in the 1970’s and gaining in much popularity during the next two decades, ecofeminism seeks to foster a connection between repression of women with the damage caused to nature and natural resources. It is based on the philosophy that both women and nature exhibit the same values and characteristics like nurturing and hence see it as the responsibility of women to undertake ecological causes. One of the most memorable events of ecofeminism occurred in Kenya when rural women planted trees as part of a soil conservation effort to avert desertification of their land as a part of the Green Belt Movement formed by Wangari Maathai. The women of Greenham Common Peace Camp were instrumental in the removal of nuclear missiles there, a fight lasting for over ten years. Sometimes ecofeminism has also been an avenue through which minority and repressed communities like the Native Americans have found their voice. Mohawk women along the St. Lawrence River established the Akwesasne Mother’s Milk Project to monitor PCB toxicity while continuing to promote breastfeeding as a primary option for women and their babies. More.

Fishing for Life

The traditional Greek fisherman casting a net from his small wooden caique is a postcard image of the Mediterranean. In the past, these fishermen supplied tavernas and fish markets. But fish stocks are so low now that many say they can’t make a living. Reason? Commercial trawlers scoop most of the fish out of the sea, there’s over-exploitation of marine wealth, and fishing regulations are lax. National Public Radio tells this story from the port of Laki, a fishing village on the Aegean island of Leros:

It’s a sunny afternoon on the port of Laki, a fishing village on the Aegean island of Leros. The seaside tavernas are filled with happy tourists and local families listening to traditional violin music and eating fresh grilled fish. But fisherman Parisi Tsakirios is not celebrating. He’s on his wooden fishing boat, cleaning a bright yellow net. Two days at sea, he says, and barely a catch.”We caught just 20 pounds of fish,” says Tsakirios, who, at 29, has been fishing for 15 years. “We can sell that for 200 euros (about $225). But fuel costs almost as much, so we’ll be lucky if we make 20 euros (about $22).”

Nature may be wild, but that doesn’t mean anything goes anywhere, and many animals follow strict rules for separating metabolic ingress and egress, and avoiding sources of contamination. Want examples? Take the Northern Flicker. According to a new report in the journal Animal Behaviour on the sanitation habits of these tawny, 12-inch woodpeckers with downcurving bills, male flickers are more industrious housekeepers than their mates.

Researchers already knew that flickers, like many woodpeckers, are a so-called sex role reversed species, the fathers spending comparatively more time incubating the eggs and feeding the young than do the mothers. Now scientists have found that the males’ parental zeal also extends to the less sentimental realm of nest hygiene: When a chick makes waste, Dad, more readily than Mom, is the one who makes haste, plucking up the unwanted presentation and disposing of it far from home.

Queensland – said to be Australia’s dirtiest state (discarded rubbish recorded at levels almost 40 per cent above the national average). Also home to Moreton Bay, the only place in the country where dugongs gather in herds and which has a significant population of the endangered loggerhead sea turtle. Over celebrating its coastal flora and fauna on World Oceans Day, the state and its leaders found themselves mulling a ban on single-use plastic in the area. Here’s why.

Let’s talk social behavior. We know much about human relations and the social activities of animals like the chimpanzee. But how about underwater? Yes, the waters, too, are filled with social interactions if rapport between coral groupers and giant moray eels are anything to go by. Several studies have followed how the duo teams up to hunt and have their own ‘code’ of vigorous shimmying, head-stands and head-shaking to communicate about prey. Now, while gestures are commonplace among humans and are expected of intelligent animals like monkeys and dogs, how do fish manage this complex communication with their tiny brains? Redouan Bshary may be the man with the answers.

Be it the flash floods in Texas or a heat wave in India that has killed over 2,000 people to date, the signs of global warming and the consequent extremes are telling on land. The sea has not been spared either –  the acceleration of global sea level change from the end of the 20th century through the last two decades has been significantly swifter than scientists thought. And a closer look at the oceans reveal that by the end of the century, the polar regions may have some of the most abundant sea life on the planet. The tropics, which are currently the crown jewel of marine species richness, may be drained of much of its iconic marine life, opines a recent study published in the journal Nature Climate Change. 

If warming is held at the 2-degree target, the changes that will occur throughout the global ocean “will be relatively benign for the ecosystem.”The tropical regions would see a net loss in biodiversity with average global warming of 2 degrees Celsius, while polar areas could see a 300% increase in biodiversity as species seek out more hospitable areas.

Remember Carolus Linnaeus? Go back to high school where you probably heard of taxonomy first; yes, it’s his invention. Well, it was his 308th birthday last week (May 23) and each year, it is celebrated with a list. Of new species discovered the previous year. Scientists found 18,000 new species in 2014, but the top 10 are in a league of their own. How about a spider that cartwheels to escape danger or a frog that gives birth to live tadpoles?

Question time. What is the largest intact forest on the planet? If you guessed Amazon, firstly you aren’t the only one; more importantly, you’ll have to know the answer is the Canadian boreal forests. Here are some facts: It covers a staggering 1.5 billion acres, between 1-3 billion birds flock nest and breed here each year, it alone stores 208 billion tonnes of carbon i.e 20 years worth of the world’s emissions from burning fossil fuels, and contains 200 million acres of surface fresh water alone. Yes, that’s a lot of numbers; but they are only some of the reasons for making sure these forests stay intact.

So, whether you enjoy a morning chasing warblers in Central Park’s Ramble, listening to ovenbirds sing in Rock Creek Park in Washington, D.C., scanning the Chicago waterfront for ducks or strolling the shaded paths of Mount Auburn Cemetery near Boston while vireos and tanagers flash through the old trees, you are drawing delight directly from that immense swath of unsullied northern forest.

A Case for the Wildebeest

According to the UNEP, wildebeest populations have declined in areas of southern and eastern Africa. PHOTO: Natural Habitat Adventures

The Great Migration of Serengeti National Park, designated a World Heritage Site, is legendary. The stars of this 1,200-mile odyssey are the wildebeest – 1.5 million of them – accompanied by 200,000 zebras. Every year is an endless journey for them, chasing the rains across 150,000 square miles of woodlands, hills and open plains. With them having firmly established their caliber as a species built literally for the long run, the migration spectacle should probably be the only space where the wildebeest find a mention. But conservation debates are hovering over these beasts – categorized as non-threatened by the IUCN – and looking at them as a keystone species.

Planting the Oak Back in Oakland

What’s in a name… Shakespeare’s 400-year-old line is timeless and oft repeated. For it goes beyond a few syllables and rests on the very soul of the matter. And going by a few volunteers setting up an inaugural stand of 72 coast live oaks in a West Oakland park, it seems like someone felt it, too. Say Oakland and you’d invariably conjure up images of woodlands and acorns. That and given that the oak is America’s national tree, you’d expect vast woodlands and tributaries of branches. Instead, sentiment is attached to the few oaks that still stand their ground in the face of development and there’s a “re-oak” campaign underway. In good time, we hope.

“Names are a powerful way to think about a place,” said Walter J. Hood, a landscape architect and professor at the University of California, Berkeley, who lives and works in Oakland and came up with the idea of resurrecting the city’s forgotten groves. “If a landscape changes, your way of life changes,” he said, “whether it’s a freeway cut into a neighborhood or a new dense canopy of trees.”

Lichens: Unlikely Citizen Science Subjects

We’re avid fans of citizen science, in part because of its breadth of possibilities. People can study historical documents, look for birds, record phenologies in forests, hunt lionfish, count butterflies, and perform dozens of other activities to help discover more about the world around and before us. One thing we didn’t expect to ever see was a citizen science initiative covering something as seemingly — but obviously looks can be deceiving — as lichens. Lisa Feldkamp reports for The Nature Conservancy’s science blog, Cool Green Science, excerpted in parts below:

Welcome to the exciting world of lichens. And no, that’s not oxymoronic.

A lichen is actually a composite organism: algae or cyanobacteria living with a fungus symbiotically. That definition, admittedly, doesn’t help their charisma factor.

But look at them closely and you’ll see a wonderful, colorful tapestry.

Get out a hand lens or microscope and an even more amazing world is revealed.

“One of the cool things about lichens is their ability to survive extremes,” says Tiffany Beachy of Great Smoky Mountains Institute at Tremont. “When it’s dry they shrivel and look like they’ve dried out, but with a drop of water they turn green.”

One of the most unique inhabitants of lichen is the tardigrade (a.k.a. water bear) is the first life-form with a proven ability to survive in the vacuum of space.

However, lichens have an Achilles’ heel: air pollution.

If there’s one certain takeaway from this blog, it’s the enduring and growing love for the feathered friends. In India, the conservation debate often touches on the Great Indian Bustard (GIB), which has an ostrich-like appearance and is labelled as “critically endangered.” In fact, the world population of the GIB is pegged at 150, with India, particularly Rajasthan, being home to 70 per cent of this number. Loss of the Bustard’s dry grasslands and scrub habitat, increased hunting and changes in land use have been blamed but Dr Pramod Patil refused to let things settle at that. Precisely why his pioneering work in protecting the Bustard population in Thar desert of Rajasthan won him the Whitley Award this year. Popularly known as the ‘Green Oscar’ and also won by compatriot Dr Ananda Kumar for his system to reduce man-elephant conflicts in India, the award carries a grant of £35,000. More importantly, it puts the focus back on the Great bird.

#PeopleVsShell

Environmental Activism has never taken a back seat in Seattle and we continue to root for the individuals, organizations and public officials who are working to draw global attention to a possible environmental disaster. Certainly not the moment to “Keep Calm & Carry On”…

Hundreds of kayakers in Seattle were preparing to go and “shake their paddles” in protest at a newly arrived 400ft long, 355ft tall Royal Dutch Shell oil rig on Saturday, with hundreds – perhaps thousands – more scheduled to attend on dry land.

“We here in Seattle do not want Shell in our port. We want them to get out and change their business before they change our planet and destroy the life of future generations,” said Annette Klapstein, a 62-year-old retired attorney and member of activist group the Raging Grannies.

On Monday, the Obama administration effectively gave Shell the green light to restart its Arctic drilling and exploration operations with an approval issued by the Bureau of Ocean Energy Management, a governmental regulatory agency.

Shell was forced to halt its Arctic exploration in 2012 amid a series of severe security mishaps.

Environmental groups and scientists reacted to Monday’s news badly, warning that letting Shell back into the Arctic for exploration and drilling was very likely to cause an ecological disaster and contribute to climate change. Continue reading →

We Love Salamanders, But Their Invasion Must Be Stopped

Pressure Builds for Swift U.S. Action Against Spreading Salamander Threat

By ANDREW C. REVKIN

There are signs of hope for American salamanders in the face of a potential biological catastrophe — a fungus that could be carried here through the global trade in exotic pets. Federal wildlife officials have signaled a crackdown may be coming on imports of amphibians.

Here’s the sequence of events.

Last year, biologists identified a virulent imported fungus, Batrachochytrium salamandrivorans, as the cause of a steep drop in salamander populations in continental Europe. Herpetologists quickly began pressing United States agencies and officials (Dot Earth, Op-Ed article) to clamp down on the global exotic pet trade to cut the chances of the disease reaching the United States — which has the most diverse salamander population in the world.

In March, experts renewed their calls for action, frustrated with the lack of acknowledgement by federal wildlife agencies that this was an urgent issue. Continue reading →

Although he may not use the term, George Monbiot believes in biophilia. His devotion to the concept of rewilding is evident in both his actions and his words, and his expressive writing about nature’s resilience and the richness of “ecological interactions” prove the point. His description of a recent trip to the Scottish highlands exemplifies both the draw of nature and his response to it:

As I came over a low ridge, I noticed a disturbance in the water below me, a few metres from the shore. I dropped into the heather and watched. A moment later, two small heads broke from the sea, then the creatures arced over and disappeared again.

After another moment, the larger one – the dog otter – scrambled out of the water with something thrashing in its mouth. He dropped it on to the rocks, gripped it again, then chewed it up. Then the bitch emerged from the sea beside him, also carrying something, that she dispatched just as quickly. They plunged in again, and I watched the trails of bubbles they made as they rummaged round the roots of the kelp that filled the shallow bay. Continue reading →

Team Sapsucker, the Cornell Lab of Ornithology’s competitive birding team, has participated in the World Series of Birding for quite some time. We’ve even had a couple of the Lab’s student participants, Team Redhead, as contributors to the blog. Over the last several years, Team Sapsucker has been breaking or coming very close to the US record for a Big Day — the most bird species seen or heard in 24 hours — but this year, ten days from now in fact, the team will be in Panama instead of staying in the southwestern US! Here’s what Chris Wood, captain of Team Sapsucker and eBird’s project leader, has to say:

The time of year has come when migratory birds cross continents and even hemispheres to return home to their nesting grounds. Because long-distance migrants face many hazards during their journeys, Team Sapsucker, the Cornell Lab of Ornithology’s top birding team, has chosen to spend 24 hours of non-stop birding in Panama, a region critical to the travels of migratory birds in the Western Hemisphere.

The photograph above illustrates a story in today’s Guardian in the Environment section, and addresses the readership of that publication in a manner that expects action. We had provided the executive summary of the study here that is the maritime version of a major call to action, and that was still quite a read; here, thanks to the Guardian, is a briefer read on the topic of a terrestrial call to action by WWF, one we hope that apes of all varieties can appreciate:

Hundreds of millions of acres of forest could be lost in the next two decades in less than a dozen global hotspots for deforestation, conservationists have warned.

Research by wildlife charity WWF has identified 11 “deforestation fronts” where 80% of projected global forest losses by 2030 could occur.

Up to 170m hectares (420m acres) could be lost between 2010 and 2030 in these areas if current trends continued – equivalent to the disappearance of a forest stretching across Germany, France, Spain and Portugal.

The areas are the Amazon, the Atlantic Forest and Gran Chaco, and the Cerrado in South America, the Choco-Darien in Central America, the Congo Basin, East Africa, eastern Australia, the Greater Mekong in South East Asia, Borneo, New Guinea and Sumatra. Continue reading →
