Cleantech investment fell off a cliff in 2012

Cleantech investment fell off a cliff in 2012

“You could call it the cleantech cliff,” writes the San Jose Mercury News:

Global clean-technology venture investment plunged to $6.46 billion in 2012, down 33 percent from the $9.61 billion invested a year ago, according to San Francisco-based research and consulting firm Cleantech Group.

Why such a big drop-off?

The low price of natural gas has made it harder for renewable energy to compete on cost. Venture capitalists are shying away from capital-intensive deals after seeing companies like Santa Clara-based Misasolé sold at fire sale prices. And global economic uncertainty took a toll: Several privately backed cleantech companies, including Oakland’s BrightSource Energy, were forced to shelve their IPO plans and raise additional funds from existing investors.

Political uncertainty contributed too, according to Sheeraz Haji, CEO of Cleantech Group. “That said, the entire venture capital industry contracted in 2012, so cleantech is not alone in experiencing this pullback,” he added.

The Mercury News reports that the “one bright spot belonged to SolarCity, a San Mateo-based solar financier and installer that had a successful IPO Dec. 13. SolarCity slashed its share price but ultimately raised $92 million.”

The cleantech sector is already looking brighter in 2013. Last week, a subsidiary of Berkshire Hathaway spent as much as $2.5 billion on a huge solar project, sending solar stocks soaring.

But why leave cleantech investing to the big boys? If you live in California or New York, you can get into the game yourself via just-launched Solar Mosaic, a crowdfunding service for rooftop solar projects. Don’t let Warren Buffett have all the fun.

Peer-to-peer sharing went big in 2012 — and so did opposition

Peer-to-peer sharing went big in 2012 — and so did opposition

This year, ride-sharing services Lyft and Sidecar amassed millions in new funding. Uber, which lets passengers hail idle town cars with their smartphones, expanded to new cities from San Francisco to New York. And Airbnb, which makes it easy for people to rent out their homes or rooms for short periods, expects to be filling more rooms per night than Hilton by the end of the year.

And yet, in a number of cities across the country, these businesses are illegal. New things are scary. And new things that grow really fast are the scariest.

2012 saw increased acceptance and growth in sharing and peer-to-peer businesses, presenting new options for consumers and new problems for established businesses and government regulators. As these new businesses grew, so did their collective disruptive force.

As Tim Wu wrote at The New York Times, “Change isn’t always pretty, but a healthy city is one where old systems — even the hallowed taxi medallion — stand to be challenged by the winds of creative destruction.”

New tech makes these businesses possible, but their sustained success doesn’t hinge on advances in smartphone design or social networking. We’re choosing peer-to-peer because we want to do business differently. We actually kind of want to pretend like we’re not doing business at all.

Lyft and Sidecar enable individuals with their own cars to find and drive customers, keeping the majority of the fare with a small chunk going to the company.

LyftThe detachable pink mustache lets ride-seekers know this is a Lyft.

“The big difference between the Lyft experience and the cab experience is supposedly friendliness. That’s why they bill themselves as ‘your friend with a car,’” Lyft driver Kate Dollarhyde told me. “A lot of my customers tell me they prefer Lyft because they feel more safe than they do in cabs, and also because they feel they can talk to and make friends with drivers.”

In an increasingly inhospitable, unfriendly world, peer-to-peer business sells you on, well, your peers. Lyft, which launched in San Francisco this summer with plans to expand into Seattle and Los Angeles in 2013, is selling community. But it’s also selling savings. Dollarhyde says Lyft trains drivers to inform customers that the rides cost about $4 less than a cab.

Even with those lower fares, Lyft can be a real source of income for drivers: “I make more money driving for Lyft per hour than I have doing anything else,” said Dollarhyde.

Airbnb can also be a significant moneymaker for participants. ”Ultimately, we want to empower people and we have thousands of people around the world that are making an incredible, meaningful amount of revenue,” Airbnb cofounder and CEO Brian Chesky told CBS. “We’ve helped thousands of people stay in their homes.”

Peer-to-peer business also empowers service providers to not provide services to clients with bad reputations; the companies let participants rate customers as well as car drivers and homeowners. ”At the end of every ride, passengers rate drivers and drivers rate passengers,” Dollarhyde tells me. “Five stars is the baseline; everyone starts out at the top. You deduct stars for rude behavior, like barfing in someone’s car, being a jerk, or generally making a ride uncomfortable.” If a barfy customer ends up with a bad rating, they’ll be peer-pressured out of the system by drivers who just won’t choose to pick them up.

But with great power comes great responsibility. (Sorry, had to.) While Airbnb helped a lot of houseless folks in the wake of Hurricane Sandy, with many people using the service to offer their homes and rooms for free, Uber was slammed for price-gouging during a difficult time.

A number of U.S. cities have banned different peer-to-peer businesses or tried to regulate them out of existence. Officials claim they’re protecting consumers, but Wu says complaints about the companies often “have the odor of industry protectionism.”

“Banning Airbnb helps hotels more than homeowners; banning Uber helps taxi companies more than passengers,” Wu writes. Owners of established businesses often have ties to local politicians, unlike the random guy who wants to rent out his studio while he’s out of town.

Wu suggests more flexible approaches to regulation that hinge on openness and real-time data. “Regulators could simply require Uber to disclose the prices it charged and where its cars were going. If cities wanted to ban rate hikes during emergencies, they could watch to see that the law was obeyed,” he writes. “This kind of precise, data-driven regulation could protect consumers while also protecting their right to pay for a valuable service.”

It could, but governments would have to put their fears aside first. So far, it’s baby steps. Earlier this month, California regulators began an inquiry into how to regulate ride-sharing services.

“We’re cautiously optimistic that the investigation will result in rules that will support innovation and support the benefits that Sidecar represents, which are reductions in emissions and congestion and more affordable transportation options,” Sidecar cofounder Sunil Paul told the San Francisco Examiner.

California’s regulatory commission will deliver its findings in six months — by which time a whole new corner of the peer-to-peer industry will likely be delighting new consumers and frustrating established business owners.

Marijuana growers endanger salmon, bears, and even dogs

Pot: not so green.

We’ve written before about the environmental damage done by marijuana growers — massive energy consumption, indiscriminate pesticide use, dead little forest critters, both cute and uncute. Now the L.A. Times reports that pot growers in California are also undermining salmon recovery efforts, poisoning bears, and even threatening our BFFs: dogs.

The marijuana boom that came with the sudden rise of medical cannabis in California has wreaked havoc on the fragile habitats of the North Coast and other parts of California. With little or no oversight, farmers have illegally mowed down timber, graded mountaintops flat for sprawling greenhouses, dispersed poisons and pesticides, drained streams and polluted watersheds.

Because marijuana is unregulated in California and illegal under federal law, most growers still operate in the shadows, and scientists have little hard data on their collective effect. But they are getting ever more ugly snapshots.

Here’s the bad news about salmon:

State scientists, grappling with an explosion of marijuana growing on the North Coast, recently studied aerial imagery of a small tributary of the Eel River, spawning grounds for endangered coho salmon and other threatened fish.

In the remote, 37-square-mile patch of forest, they counted 281 outdoor pot farms and 286 greenhouses, containing an estimated 20,000 plants — mostly fed by water diverted from creeks or a fork of the Eel. The scientists determined the farms were siphoning roughly 18 million gallons from the watershed every year, largely at the time when the salmon most need it.

“That is just one small watershed,” said Scott Bauer, the state scientist in charge of the coho recovery on the North Coast for the Department of Fish and Game. “You extrapolate that for all the other tributaries, just of the Eel, and you get a lot of marijuana sucking up a lot of water.… This threatens species we are spending millions of dollars to recover.”

And the bad news about bears:

Mark Higley, a wildlife biologist on the Hoopa Indian Reservation in eastern Humboldt …, is incredulous over the poisons that growers are bringing in.

“Carbofuran,” he said. “It seems like they’re using that to kill bears and things like that that raid their camps. So they mix it up with tuna or sardine, and the bears eat that and die.”

And the bad news about dogs:

Scientists suspect that nutrient runoff from excess potting soil and fertilizers, combined with lower-than-normal river flow due to diversions, has caused a rash of toxic blue-green algae blooms in the North Coast rivers over the last decade.

The cyanobacteria outbreaks threaten public health for swimmers and kill aquatic invertebrates that salmon and steelhead trout eat. Now, officials warn residents in late summer and fall to stay out of certain stretches of water and keep their dogs out. Eleven dogs have died from ingesting the floating algae since 2001.

Though California has yet to follow Colorado and Washington in legalizing pot, “[m]arijuana is, as a practical matter, already legal in much of California,” reports The New York Times, so common that it doesn’t even raise eyebrows. Gavin Newsom, California’s lieutenant governor and a likely future gubernatorial candidate, says the laws against marijuana “just don’t make sense anymore”; he’s now calling for legalization.

But with the federal government still resolutely anti-weed, even many growers in states where marijuana is legal are likely to stay in the shadows and keep using shadowy growing techniques — so get used to bad news.

Obama doubles size of California marine sanctuary, adorable otters rejoice

Obama doubles size of California marine sanctuary, adorable otters rejoice

President Obama has proposed that more than 2,700 square miles off the coast of Northern California be added to the national marine sanctuary system, which would protect the area from oil and gas drilling permanently. It would be the biggest addition to the 40-year-old system in 20 years, doubling the total protected sanctuary area. The otters are so excited you guys.

mike baird

From the San Jose Mercury News:

“This is a matter of economic common sense. Jobs and livelihoods hang in the balance,” [said Rep. Lynn Woolsey (D)]. “No one is going to vacation on the Sonoma coast if they are looking at oil derricks.”

I like her logic, even though lots of people vacation along the California coast within view of all kinds of offshore drilling equipment. (Ahem, Santa Barbara.)

In recent months, Woolsey, who is retiring from Congress on Jan. 3, urged Obama to use his executive authority to create a new national monument along the scenic Sonoma coast. Obama, however, stopped short of creating a monument, opting instead to use the NOAA administrative process, which triggers public hearings in Northern California early next year, along with detailed environmental studies. It is expected to take up to two years to finalize …

“This is one of the crowning achievements of the coastal protection movement in California,” said Richard Charter, a senior fellow with the Ocean Foundation in Washington, D.C. “This is a permanent ban on offshore drilling, forever, at a time when Congress has not been particularly interested in conservation.”

The Sierra Club said, “President Obama gave Californians and all Americans a tremendous gift today.” But this is particularly great news for nature, which would really prefer to do whatever the hell nature wants.

While Northern California’s coastal sea otters are poised to get an expanded sanctuary, earlier this week Southern California’s otters got some good news too. The federal government is officially abandoning its effort to keep otters near a remote island — an effort that resulted in most of the otters dying — and will now let them float free. From the San Francisco Chronicle:

“Trying to tell a marine mammal to stay on one side of an imaginary line across the water was a dumb idea,” said Steve Shimek, executive director of the Otter Project.

Shimek said the otters’ new freedom will help restore the coastal ecosystem of Southern California (near those offshore drilling operations, natch).

From KPCC:

Otters are good for kelp forests. And kelp forests, called the “redwoods of the sea,” are home to hundreds of species valuable to a biologically diverse coastal ecosystem.

Things are looking up for this Christmas, Ma and Emmett Otter!

Controversial California oyster farm fights to stay

Controversial California oyster farm fights to stay

It’s a salty Christmas miracle for Drakes Bay Oyster Company — albeit a temporary one.

two_wrongs

The bivalve purveyor in Point Reyes, just north of San Francisco, was set to be dissolved at the end of the year: equipment dismantled, employees laid off, land vacated. This was the plan all along for the feds, who had issued a 40-year lease to the company with the intent of its expiration on Jan. 1, 2013, at which time the land would be returned to federal wilderness and cute scampering seals on the Point Reyes National Seashore.

After the Interior Department refused to extend the company’s lease for another 10 years, Drakes vowed to fight the decision and filed suit. Now it’s reached at least a temporary agreement with Interior. From the Marin Independent Journal:

Under the agreement, the oyster company which has long been a fixture in Point Reyes National Seashore may continue activities involving planting and growing new oysters in the water at Drakes Estero, avoiding layoffs of one-third of its 30 employees right before the holidays …

Under the agreement, the oyster company has withdrawn its request for a temporary restraining order and instead will file a motion for a preliminary injunction challenging [Interior Secretary Kenneth] Salazar’s decision.

A hearing is set for Jan. 25 on the injunction.

Everyone loves them some seals, even in molting season (this is saying a lot, seals), and many environmentalists — the Sierra Club, the Natural Resources Defense Council, other usual suspects — support closing the farm, citing the importance of pure wilderness. But many other environmentalists support letting it stay, and their voices have grown stronger over the past couple of weeks. Writes Earth Island Journal editor Jason Marks:

Wilderness is all too rare (and becoming rarer) and we need more places that aren’t stamped with humanity’s insignia.

But Drake’s Estero is not that place. Having followed this controversy for years — and having spent several spells living in Point Reyes Station, the hamlet at the edge of the park — I strongly believe the oyster farm should stay.

It seems to me the debate over the ecological impact of Drakes Bay Oyster Company is all backwards. The issue isn’t whether shellfish farming is compatible with the ideal of wilderness. Rather, it’s whether a wilderness is compatible with the pastoral landscape that surrounds Drake’s Estero …

A National Academies of Science report from 2009 said the data on oyster farm-related harbor seal disturbance was so thin that it “cannot be used to infer cause and effect,” and called for “a more detailed assessment.” A professor from UC-Davis who reviewed the Park Service’s draft environmental impact study on the oyster farm removal observed that “impacts of oyster aquaculture on birds are speculative and unsupported by peer-reviewed publications.”

Some locals say the feds even took their comments out of context, misrepresenting them as being against the farm when they support it. One kayak touring company said paddling in the estero has only gotten more pleasant in recent years, under Drakes’ new ownership. “Not only have they cleaned and improved the physical location but they offer an educational and historical component that enhances our client’s experience of the area.” The kayakers also said they rely on the farmers for potential emergency rescue.

In the meanwhile, Drakes is still farming and harvesting per usual, and open for business. And if you’re feeling crafty, you can hit up its massive piles of castoff oyster shells and DIY one of these very eco-friendly holiday trees.

California releases draft rules for regulating fracking

California releases draft rules for regulating fracking

Jerry Brown, the once-and-current king (governor) of California, yesterday announced a draft proposal for regulating fracking. Because if there’s one thing California needs, it’s more fissures beneath it. And/or more earthquakes.

Though that’s not the tack Brown took. From the L.A. Times:

The proposed rules, released Tuesday, would require energy companies to disclose for the first time the chemicals they inject deep into the ground to break apart rock and release oil. They also would have to reveal the location of the wells where they use the procedure.

Though fracking has unlocked vast amounts of previously unreachable fossil fuels elsewhere, environmentalists and public health advocates in California have raised safety questions about the hundreds of chemicals used — many of them known carcinogens — and the potential for drinking water contamination.

I mean, nothing about the earthquakes? Well, you’re the governor.

Wikipedia

Oil pumps near I-5.

The region that has oil companies salivating is the Monterey Shale, a stretch of rock running from Modesto through the Central Valley of the state, which some think could contain 300 billion barrels of oil. At today’s per-barrel price, that’s $26.4 trillion dollars sitting under a bunch of walnut groves and cattle ranches.

But California has a … complicated relationship with fossil fuel extractors, dating back to Daniel Plainview’s New Boston strike. It’s been the first (and only) state to enact a cap-and-trade system to reduce carbon emissions, and voters defended that plan, overcoming millions in oil company funding. Also, California votes Democrat about 90-to-10 (except Southern California).

So you can see the friction. It’s like the San Andreas fault of politics: Big Oil versus the State of California. Even with this draft proposal, there are concerns that the state isn’t creating friction enough.

Environmental and industry groups said the draft regulations were a good first step in what is expected to be a lengthy rule-making process. But environmentalists signaled a coming fight over the level of disclosure, noting a provision that would allow oil companies to withhold disclosure of chemicals they claim to be proprietary. …

A recent analysis by Bloomberg News found that companies nationwide withheld from their disclosure reports one out of every five chemicals they used in fracking.

The “lengthy rule-making process” can’t happen fast enough. As the Times notes, a federal auction last week in Sacramento leased nearly 18,000 acres of shale land in 10 minutes.

And, not to beat a dead horse here, but the state really might want to consider that it is riddled with geological faults — not in the Central Valley, to be sure, but even there earthquakes occur. Especially if you start breaking apart rock and injecting fluids to make it slip around more. And what about already-leak-prone wastewater disposal wells lined with cement? The U.S. Geological Survey suggests that there is a 62 percent chance the Bay Area will see a 6.7-or-stronger quake by 2032. The odds that a major earthquake won’t have ripples 100 miles away near Modesto are slim.

Just something to think about. Good luck with the rule-making process. Try and beef it up. And, if you can, try to get it done before 2032.

Traffic deaths are down, but pedestrian and cyclist deaths are up

Traffic deaths are down, but pedestrian and cyclist deaths are up

Fewer people are dying in car accidents in the U.S. (except in California, where it’s been raining lately and people have been very confused). Traffic deaths fell 1.9 percent in 2011, hitting their lowest level since 1949.

That’s great news for drivers, who haven’t been getting a lot of good news in their driver-lives lately. Here’s the bad news: Drivers are killing the rest of us. The Los Angeles Times reports on new federal transportation figures:

Federal officials highlighted the overall decrease in [traffic] deaths. But at least one traffic safety group said the figures were alarming, particularly a 3% increase in pedestrian deaths and an 8.7% increase in cyclist fatalities from 2010 to 2011.

“We are still concerned about the numbers of cyclists and pedestrians at risk on our roadways,” said Paul Oberhauser, co-chairman of the Chicago-based Traffic Safety Coalition, which is partly funded by the traffic safety camera industry. “This new report is a reminder we still need to be cautious and share the road.”

Rory Finneren

Speaking of sharing the road, today Bike Score, an offshoot of Walk Score, rolled out more city ratings for bikeability. It turns out even many of the towns we consider cycle-friendly — like New York and Portland, Ore. — are barely getting a passing grade.

So if you’re walking or biking around right now, and you haven’t died yet, congratulations! NOW STOP READING THIS.

The EPA tightens limits on soot, predicting huge health benefits

The EPA tightens limits on soot, predicting huge health benefits

At least there’s a bit of good news today: implementation of hard-fought public policy that will have a hugely beneficial effect on public health.

The EPA’s tightened standard on soot pollution — announced in June and sent for final sign-off to the White House earlier this week — has been approved.

National Archives

From The Washington Post:

The new rule limits soot, or fine particulate matter, which stems from activities ranging from burning wood to vehicle emissions, and which causes disease by entering the lungs and bloodstream. Fine particulate matter measuring less than 2.5 micrometers in diameter, or one-thirtieth the width of a human hair, ranks as the country’s most widespread deadly pollutant.

The new rule is a result of a 2009 court ruling that said the EPA standards for the amount of soot permissible in the air on an annual average ignored the advice of scientific advisers by maintaining the standard established in 1997 and must be rewritten. That limit was 15 micrograms per cubic meter of air.

The EPA cut the level to 12 micrograms per cubic meter.

That new level is actually on the lower end of what the EPA was considering — still higher than the 11 micrograms some health advocates sought, but significantly better than it could have been. At 12 micrograms, the EPA expects that America will save between $2.3 and $5.9 billion a year in health costs. By 2020, that figure could rise to $9.1 billion annually. The Sierra Club’s Mary Anne Hitt notes that as many as 15,000 premature deaths will be prevented annually. Other soot-related health problems that the new rules will help prevent, according to the EPA:

nonfatal heart attacks,
irregular heartbeat,
aggravated asthma,
decreased lung function, and
increased respiratory symptoms, such as irritation of the airways, coughing or difficulty breathing.

Another benefit: The new limit will also improve visibility at national parks. And you’ll be alive to enjoy the views.

For states and counties, meeting the new standard may not be that difficult. An EPA compliance map suggests that only seven counties — all in California’s Central Valley and Inland Empire — won’t meet the new standard by the end of the decade.

MAP

EPA

The industries responsible for particulate pollution said what you’d expect, according to The Hill.

Several industry groups, including the National Association of Manufacturers (NAM) and the American Petroleum Institute, opposed the tougher rules and warned they would thwart economic growth. NAM CEO Jay Timmons slammed EPA’s decision on Friday and said the agency should stick with the standards set in 1997.

“This new standard will crush manufacturers’ plans for growth by restricting counties’ ability to issue permits for new facilities, which makes them less attractive for new business. Essentially, existing facilities will have to be shuttered for new facilities to be built in these areas,” Timmons said in a statement.

This is what is always said.

The soot regulation is good news: lives saved, preventable damage prevented, lobbyists defeated. Now if only we could be so rational in other areas of public policy.

Could clones save California’s endangered redwoods — in Oregon?

Could clones save California’s endangered redwoods — in Oregon?

True story: My grandmother built her California house entirely from redwood. It’s a really nice house! But it makes me pretty uncomfortable to be inside the place with its massive beams made of ancient, dead trees when we’ve got only 5 percent of old-growth redwood forest left standing today. And as the climate keeps heating up, those trees will be subject to new dangers — and new potential for rebirth further north.

friendshipgoodtimes

According to new research published in the journal Science, the California redwoods, American pines, Australian mountain ash trees and other living giants are in danger of being lost forever if we don’t change how we treat them.

Just as large-bodied animals such as elephants, tigers, and cetaceans have declined drastically in many parts of the world, a growing body of evidence suggests that large old trees could be equally imperiled.

From The Bangkok Post:

The study showed that trees were not only dying en masse in forest fires, but were also perishing at 10 times the normal rate in non-fire years. The study said it appeared to be down to a combination of rapid climate change causing drought and high temperatures, as well as rampant logging and agricultural land clearing.

“It is a very, very disturbing trend,” said Bill Laurance of James Cook University.

“We are talking about the loss of the biggest living organisms on the planet, of the largest flowering plants on the planet, of organisms that play a key role in regulating and enriching our world.”

Large old trees play critical ecological roles, providing nesting or sheltering cavities for up to 30 percent of all birds and animals in some ecosystems.

Some people are now taking action to save the remaining redwoods and repopulate West Coast forests with new-old trees. In Santa Cruz, activists are trying to raise millions to purchase a section of old-growth forest. And this week in Oregon, the Archangel Ancient Tree Archive began planting 250 clones from 28 of California’s biggest, oldest redwoods and sequoias on the southern Oregon coast. From the Associated Press:

David Milarch, co-founder of the Archangel Ancient Tree Archive and the Champion Tree Project, hopes the small plantation south of Port Orford, Ore., will give the ancient giants a leg up on moving north to cooler climes as the climate changes and be the start of a campaign to plant some of the world’s fastest-growing trees all around the globe …

The clones will be planted on Terry Mock’s 150-acre Ocean Mountain Ranch. Mock is a former director of the Champion Tree Project and is turning the ranch into a demonstration of sustainable development. They will go into the ground on the sheltered north slope of a ridge about a mile from the coast near Humbug Mountain. The site is about 40 miles north of the northern tip of the coast redwood’s range, and about 700 miles north of the sequoias in California’s southern Sierra Nevada.

“As things get hotter and drier, redwoods and sequoias should migrate north,” Mock said. “This is a logical spot.”

Another little bit of good news? Until we act like short-sighted jerks and cut them down, it turns out those individual massive trees are still growing. Researchers just found the world’s number 2 biggest tree has actually been dwarfed by its number 3 rival, dispelling the notion that big trees grow more slowly as they age.

California pot farms poison animals, cute and less cute alike

California pot farms poison animals, cute and less cute alike

Mourad Gabriel is not feeling very mellow, dudes. The Northern California wildlife disease ecologist has been tracking and studying forest-dwelling fishers for the last 10 years, but lately he’s become more of a wildlife coroner.

First, let’s get this out of the way: Fishers deserve your sympathy, but they are not very cute.

A part of the weasel family, cat-sized fishers have hunted turkeys and bobcats, and have few predators besides humans, who used to poach them for fur and now just kill them with pesticides on illegal marijuana farms. From On Earth:

Fishers once roamed our northwestern forests in abundance, but their numbers have dwindled dramatically in the region. Now Gabriel, 38, believes he has unlocked the mystery as to what’s keeping this species from bouncing back. And his discovery, alas, is what has outlaw pot growers reaching for their guns …

“I’m not focused on the pot plants,” Gabriel says. “What makes my blood boil is the environmental damage being done on public land.”

Hit hard by fur trapping and the logging of the forests they favor, fishers had all but vanished from their historic range by the early twentieth century. Gabriel describes them as an “umbrella species,” meaning that they tend to be good indicators of their ecosystem’s overall health. By studying the remaining fishers closely, biologists can get a sense of how other members of their ecosystem are faring.

Fishers live and hunt in mature forests that provide great cover for surreptitious weed grows — grows that are actively poisoning the land and its creatures, adorable and ruthless alike. Gabriel surveyed the scene at one Humboldt County marijuana farm, post-raid.

Pesticide containers were scattered across the landscape, their poison baits marked with countless scratches made by the gnawing teeth of mice and rats. The pot growers, it soon became clear, were spreading large amounts of rodenticide around their plants to protect them from tiny pests. The rodents were living for several days after eating the poison — just long enough to be preyed on by fishers.

Gabriel began to document the stunning quantities of rodenticide that were peppering the 144 square miles of the Hoopa reservation. On one grow site near the reservation, 90 pounds were discovered. He calculates that 10.5 pounds (the amount he found at one of the first sites he studied) is enough to kill 12,542 deer mice or 1,792 wood rats — and anywhere from 5 to 28 fishers.

Outdoor cannabis farming may be more sustainable than the inside kind, but it’s all bad news for the environment. Maybe Humboldt State University’s new marijuana institute could research not just the plant itself, but its effects on the area’s own ecosystem.
