Rainforest's chewing gum tappers go organic to get out of a sticky situation

Jo Tuckman in Calakmul

Porfirio Baños takes the measure of the chicozapote tree that he is about to tap for its resin. He winds a rope around himself and the tall, straight trunk that stretches towards a glimpse of sky through the foliage above. He starts to climb.

"I started following my dad around the rainforest when I was 10 and working when I was 12," the 50-year-old says as he cuts through the bark with a razor-sharp machete. A bright white sap called chicle runs down the wound in the wood, prompting a smile. "I am a chiclero to my core."

The location is remote, the practice old, the tools rudimentary, and the chances to chat with spider monkeys high. But this is no world apart. Men like Baños were at the root of one of the great consumer phenomena of our time: chewing gum.

Produced only in the jungle that straddles the southern part of Mexico's Yucatán peninsula, northern Guatemala and Belize, chicle was the basis of chewing gum, from the little balls first sold in New York 140 years ago to the sticks included in GI rations during the second world war. Then in the 1950s came synthetic substitutes that shrank the industry to a shadow of its former self.

Biodegradable

But just as it was beginning to look as if the chicle industry would fade away altogether, Mexico's chicleros may be on the threshold of a comeback: they are about to launch their own brand of certified organic chewing gum, which is expected to go on sale shortly in Waitrose.

A bonus of the new gum for Britain's local authorities is that it will be biodegradable and start to break down almost immediately after use, potentially saving councils millions in pavement cleaning bills.

The epic tale of chicle goes back to 1869 when a Mexican general called Antonio López de Santa Anna was living in exile on Staten Island trying to raise money. He enlisted a local inventor called Thomas Adams to test out his idea that chicle, long chewed by Mexican soldiers in unprocessed form, could be transformed into a lucrative rubber substitute.

When vulcanisation failed the general moved on, but Adams, left with a tonne of the stuff to shift, came up with what turned out to be a brilliant idea. He added sugar and flavouring, and chewing gum was born. Within a few decades the sap once used by the ancient Maya to clean their teeth had become a symbol of modernity. Michael Redclift, author of Chicle: Fortunes of Taste, calls it "the American product for the American century".

Alfonso Valdez caught the tail end of the chicle fever that invaded the still largely virgin jungle during the boom years. "The chiclero camps were like small towns and there were dances every weekend," the 69-year-old says, reminiscing about the communities accessible only by small plane and lots of walking. "Nobody dared leave before the season was over, and if they tried to walk out alone we would find their torn-up clothes and assume they'd been eaten by a jaguar." Valdez now runs a much more modest camp at the end of a logging track on the edge of the Calakmul rainforest reserve where Baños and another nine veteran chicleros have lived since July and will stay until February.

The job itself has changed little, with each chiclero fanning out into the forest at dawn alone and earning according to how much chicle they bring back to camp at night.

The price for the raw material is too low to attract local youths who prefer to look for dishwashing jobs in Cancún or New York. These may be the last of the chicleros.

The administrators of the chiclero co-operative developed Chicza Rainforest Gum as a last-ditch attempt to save the industry. They struck a deal with Waitrose last year, they say, after touting their product around European organic food fairs. They hope it will be in 100 stores early next year.

Waitrose says it is excited about the product. "We are extremely interested in the Chicza chewing gum," said confectionery buyer Matthew Jones. "It is a great product that is organic and sustainable so we are very excited about its potential in our stores."

Valdez, an ageing chain-smoking toothless charmer who says he has fathered 42 children, is optimistic despite the global recession: chewing gum was one of the few consumer goods to thrive in the Depression. There is the added incentive that it eventually turns to dust. The annual bill for cleaning pavements of gum in the UK is more than £150m.

Chicza's packaging, meanwhile, pushes the new gum as a saviour of a rainforest in danger. The chicleros see preserving the forest as part of their job. "We don't kill the trees like farmers do when they clear land to grow corn or graze cattle," says Roberto Aguilar, 60. "We leave a wound, it's true, but eight years after it is healed and producing chicle again."

Deadly fears

But these workers of the jungle do harbour two fears, and harbour them deeply: the poisonous snakes whose bite kills in hours, and the slip of a machete that can cut the rope holding them above ground. All have lost friends and family to both.

"He just said: 'I'm finished, look after yourselves'," Baños says, recalling his father's last words at the foot of the chicozapote tree he fell from six years ago. The hardened old chiclero allows himself a moment of pathos - but then he's off again, looking for another tree to climb.

Fishermen Make Mad Dash For Dungeness Crab


by Richard Harris

The moon hangs over the harbor at 4 a.m. in Crescent City, Calif., and a soft foghorn sounds in the distance as boats head out to sea to catch delectable Dungeness crabs.

This isn't just a quaint early-morning tradition. It's a race to catch all the crabs before other crabbers get to them first.

Dungeness crabs are not only a winter treat; they are also the most valuable catch on the West Coast. More than 400 boats ply the waves in the early winter and lay their crab pots off the coast of California, Oregon and Washington.

Brett Fahning is one of those crab fishermen. Fahning is a baby-faced 35 and sports a goatee. And despite this morning's flurry of activity, this port is a mere shadow of what it was decades ago. Two-thirds of California's commercial fishermen have abandoned their businesses in the past 15 years.

But Dungeness crab is one bright success story. The rules for keeping this fishery healthy are simple. Fishermen catch only large male crabs, and only in a defined season.

"It's just like a no-brainer sustainable fishery; it always has been," Fahning says.

An Arms Race

Natural cycles make the crab populations boom and bust, but biologists say fishing is not a threat to the crabs. That's true even though there is an absolute frenzy when the season first opens.

"It's kind of a derby fishery," he says, noting that 80 percent of the crabs are caught in the first two weeks of the season.

There are only so many crabs, and they get scooped up fast during the bonanza days. After that, it's slim pickings. So there's a race to grab them before they're gone.

And more fishermen are joining the derby every year, meaning fewer crabs per vessel. Boats that once caught other species are now turning to Dungeness crabs. That includes vessels that used to go out for salmon, until that fishery collapsed a few years ago.

"More guys are focusing on Dungeness crab and investing [in] Dungeness crab — meaning they're buying more pots, more gear, upgrading their boats," Fahning says.

It's become an arms race to catch crab. And as a result, economist Steve Hackett at nearby Humboldt State University says, there's a huge over-investment in the crab fishery. There are something like 170,000 crab pots off California, about three times as many as you'd need to catch all the crabs in a season. Those excesses also make crabbing less profitable.

The race for crab is also dangerous. It's the deadliest fishery on the West Coast, with fatalities just about every year. Fahning says some fishermen are just too anxious to get in on the early days of the race, weather be damned.

"I mean, I know the kind of boat I have here — it's an old wood boat. I'm obviously not going to go and fish in conditions that I shouldn't be fishing in. And you just have to use your head and be safe, and a lot of times guys don't do that," he says.

Captains also sometimes fall asleep at the ends of their long days and run up into the rocks.

So safety and money issues have led crab fishermen to establish a task force to find ways to make their business more rational. A rational season would also mean more fresh crab. Right now, with the huge burst at the beginning of the season, most gets frozen.

Pulling Up Crabs

Fahning slows the Rogue, his 58-foot-long fishing boat, as he arrives at his first string of crab pots. He has about 450 in the water, and the crew needs to start pulling them well before dawn if they have any hope of harvesting all their crabs today.

Standing on deck behind the wheelhouse, Bobby Kissinger uses a winch to pull up a crab pot. It takes just a few seconds to bring the cage up through 120 feet of water. The crew scoops out a couple of writhing crabs. They're brown, glistening crustaceans, about 2 pounds apiece. The crew tosses them into a bin, rebaits the trap and tosses it overboard.

They'll do that more than 400 times today, Kissinger says. "Yeah, we get in a zone and we stay there for 12 to 18 hours."

As soon as one pot is done, the boat is up to the next buoy. Kissinger and his deckmate Andy Allen have their timing down to the second. Allen says most important is Kissinger's control over the winch, which keeps the 100-pound crab pots from flying out of control.

"Everything's riding on that hand," Allen says. "If his hand slips, makes the wrong move, then we're dead men."

Pot after pot comes onboard. There are five crabs in one, a dozen in another. Some contain nothing but giant starfish.

Fahning watches the action from the wheelhouse. He's a transplant from Wisconsin, educated as an oceanographer but hooked on the business — and sport — of fishing. As each crab pot comes up, he eyes it eagerly, to gauge his luck.

This is a slow season for crabs, but, he says, "I think it's going to pan out OK. It's not going to be a disaster."

Slowing The Race

Fishermen could potentially make life easier for the entire crab industry if they could find ways to slow their expensive and dangerous arms race.

"There have been suggestions of making it a daylight fishery only — no lights are allowed, you can only go fishing during the day," Fahning says.

Another idea is to limit the number of crab pots allowed in the water. He is not wild about either idea.

"I don't think its fair to try and equalize, to socialize the industry," he says.

The truth is that he likes the risks and rewards of the crab business, and he's attracted by the degree of independence life on the sea provides him.

"Really, it'd be pretty hard for me to go back and get a real job after this," he says with a laugh."There's the romantic part of it, too, but I think it's just mostly the independence; the romanticism kind of wears off a little bit after a while."

And it's that independent streak, found in so many fishermen, that will make it tough for the crab fishery to agree on any changes.

Finally, around 7:30 p.m. , the Rogue ties up again in Crescent City with 4,000 pounds of crab in its hold. The crew members go their separate ways, but they will return in about eight hours and once again race out to their pots.

7 Cleantech Stories of 2008 that will Change Everything

Written by Hank Green



It can sometimes be a little unclear (especially first day of a new year) how the previous year changed the world. No one guessed in 1946 that the Magnetron Spencer Percy was developing for use in a RADAR system (and that subsequently melted a candy bar in his pocket) would one day become the microwave oven. But I like to think that we can make some pretty good guesses about which of this year's innovations are going to be with us, and changing our world, for a good long time.

Here's my list of the top ten clean tech innovations of 2008.

Light Antennas
You know how you can capture and produce radio waves with antennas? Well, what if you could built an antenna so small, it could capture and emit light? The first large array of these nano-antennas was produced this year, and the possibilities for them are endless. They may become efficient light sources, efficient solar panels, or simple ways to transfer energy we feel as heat into energy that we don't feel at all, making them a kind of passive climate control system.

President Barack Obama
Maybe not an innovation in the traditional sense, though, I like to think that it took some innovative thinking to get this man elected president. But President Obama's Administration has already grown to include clean technology advocates and researchers, and carries with it promises of green collar jobs, carbon markets, and restored protections for many of our imperiled ecosystems.

EEStor Begins to Emerge
The power storage company, EEstor, which we're still not 100% sure isn't full of crap did finally begin to tell us some things about their miraculous-sounding power storage technology. If true, vehicles could have batteries lighter than gas tanks, that could charge in five minutes and would never degrade. These ceramic "electrical energy storage units" have not yet seen the light of day (or independent verification) but they do already have contracts with Lockheed Martin and plans to deliver their first unit to an electric car company shortly.

The Gas Crunch
Hey...remember back when gas was freaking ridiculously expensive? Well, while the market may not (the Ford F-150 is, once again, America's most popular vehicle) the innovations that poured into the market to try and help consumers deal with high gas prices will not go away. Better hybrid systems, more efficient engines, massive investments in biofuels, the re-emergence of diesel in America were all direct implications of skyrocketing gas prices.

Solar at Grid Parity
The cost of delivering electrons to the grid has gone up a little bit in the past year, and the cost of delivering electrons to the grid using solar power has dropped dramatically. The first solar electrons costing roughly the same amount as natural gas electrons were produced this year. There's no reason to think that this trend will end, as natural gas gets more expensive, and solar systems get more efficient. In fact, one company is already promising solar power at the same price as coal!

Project Better Place Expands Wildly
While I'm still not 100% sure that Better Place, with it's many battery swapping stations, cell phone-like payment plans and "one sized battery fits all" platform makes the most sense, they have managed to get a lot of governments to bite. California, Hawaii, Australia and Denmark have all signed deals with Agassi's gigantically ambitious electric car program. It could all become extremely passe if EEStor's technology pans out. But otherwise it's one of the few solutions that will work now, instead of waiting for battery technology to catch up with our goals as car drivers.

Pickens Counterbalances Gore with a Real Vision
We've tired of Al Gore. The love affair was great while it lasted, but he's been attacked from too many angles to really latch onto his message anymore. But what about an ultra-conservative, Texas oil man? Now that's the kind of champion clean technology needs! And not only does he provide a different perspective, he provides a clear plan for how he wants to change our energy future. And while it might be a plan that would make him one of the richest people in the world, it's also actually a pretty good plan.
