Happy Hour Science – Domesticating Microbes for Beer

As our ancestors transitioned from hunter-gatherer to agricultural society, they had to domesticate the plants and animals we know today as farm life. Corn kernels became larger and more full of starch, cows became more docile, and all farm organisms became accustomed to life in rows or pastures tended by humans. But some of what we eat depends on more than just these plants and animals – example, take beer. A new study in PNAS by Diego Libkind et al. describes the domestication of the microbes and yeast needed to make lagers of old and describes an unwitting process paralleling agricultural domestication.

We here at the Gam always like good news and sometimes in the environmental field, it’s quite hard to come by. But Ya Like Dags describes the Win with PCS Phosphate’s expansion here in eastern NC. A major take-home point, though, is that while the case might be a win in the environment category, it’s … Read More “Posts of Note Around the Gam – July 28th, 2011” »

PCS Phosphate: Participation is necessary, whether or not it’s required

Since finding out about PCS Phosphate’s plans to build a sulfur melting facility at the Morehead City Port, the community has been swift to organize in opposition of the plant. Some of the reaction is in genuine concern about the environmental and economic impacts of the plant, but most if it circles around the fact that by the time the first public articles were released about the plant, permits had been signed and to many, the plan seemed like a done deal. All without input or comment from the public, or even from much of the Morehead City leadership.

The permit issuers are just doing their jobs – but the situation begs a larger review of state agency activity. Many state employees feel like it would help them to collaborate with people in another agency (eg regarding mercury in the Cape Fear), and in cases like this, an approach agency-by-agency can leave out the big picture. In this case, the big picture is that PCS Phosphate has yet to do a full environmental impact statement or collect any comments on the project as a whole. Sure, 4.5 kg of hydrogen sulfide a day seems ok (air permit), and it fits with the industrial zoning of the port (zoning permit). But will the addition of emitting industries compete with the tourist industry? We have no idea. In previous cases, such as the Titan Cement case in Wilmington, this has left the company open for lawsuits that have been tied up in court for years.

PCS Phosphate: Air quality permit sees light of day, stinks

We’re continuing to dig through the permits and background pertaining to the recent revelation the PCS Phosphate has nearly completed the permitting process for a new sulfur processing plant at the Morehead City Port. The most apparent environmental and health impact of sulfur processing is noxious chemical emission and a pervasive rotten egg smell from hydrogen sulfide. According to PCS Phosphate’s Environmental Assessment:

“Based on assessments of the preliminary design of the project, there will be no adverse air quality impacts associated with the project.”

The company is still required by the state to apply for a minor new source permit, so the plans must indicate the plant will be emitting something. As local residents, we have a right to know what the plant will emit, not just the company’s bottom line.

Adventures in Backyard Agriculture: A Summary and More

This week, Southern Fried Scientist and I have written about our personal adventures in making town life a little more sustainable. First, building a chicken coop – a deluxe one, complete with green roof and made out of recycled materials. Next, dwarf goats as milk-producing pets and clarifying some of the tall tales about goats (no, they don’t eat tin cans but yes, you can teach them to head butt on command). The chicken story continued with how to raise them – whether to get chicks or pullets, what they need as they grow to be egg producing hens or the cock-a-doodle-doo producing rooster. Plus, it’s hard to beat chicks in a basket. Finally, what you might have thought backyard agriculture was all about – the garden.

After our miniseries, you might be left wondering ‘now what’? Where to begin or maybe there’s still some hesitation over whether it’s all worth it. Here’s some other practical considerations you might think about before beginning your urban agriculture adventure.

Adventures in Backyard Agriculture: How to earn the fruits of your (garden) labor, literally

Brown thumbs can turn brown, I promise. The trick to vegetable gardening is similar to any sort of gardening or landscaping – know your environment. I’ve learned an immense amount about gardening since moving to the coastal plain from the more fertile piedmont region of NC. Growing vegetables in the piedmont was as easy as throwing a seed in the pile of dirt behind the house. In sandy coastal regions, not so. Here’s some of my lessons, which I think can be taken and adapted just about anywhere…

Adventures in Backyard Agriculture: Dwarf Goats

Following Southern Fried Scientist’s sustainable pets movement, two Nigerian Dwarf goats have recently joined my life. While they have garnered traffic-stopping attention in town upon their arrival, goats are not such a foreign idea to the old-timers in the neighborhood. Goats used to be fairly common in the urban homestead back when the line between city and rural was a little less clear.

Sea Shepherds of Pacific Sharks?

Palau’s new shark sanctuary covers 600,000 square kilometers of almost all open ocean, making patrolling for outlaws a bit like searching for a needle in a haystack. In addition, Palau is attempting to make its new sanctuary a model for marine conservation for other small island nations, many of which are more water than land. So the eyes of the Pacific, if not the world, are on Palau to set a model. And they’re going to need help – but the big question is from whom?

Environmental History Lessons

The sustainability movement has gained some ground in recent years, evidenced by recycling education in elementary schools, green marketing efforts, and green jobs to support new economies. Sometimes this might seem like we’re in a brave new world, but at the same time we are fighting the exact same battles citizens have been pushing along for decades – for better or worse. A recent reading of First Along the River: A Brief History of the US Environmental Movement I had a much better appreciation of where the modern environmental movement has come from and perhaps where we are going.

A Path for Sustainable Development

After our sustainability month, it becomes easy to ask for a plan to become more sustainable. On a national scale, this becomes demand for a blueprint or recipe for how to organize society successfully in the future along sustainability principles. The idea of a given trajectory of development goes back to Walt Rostow, who described development around the world up to 1960, ending with the emergence of a first, second, and third world. More modern theorists realize that the world is not linear, however.
