Gone Fishin’: Australis Aquaculture CEO Josh Goldman

JoshGoldmanaquacultureMaking responsible choices as a seafood consumer has never been more complicated. An average fish-eater might be aware that tuna is high in mercury, or that Chilean sea bass is over-fished, but even the most devoted environmentalists usually have to refer to their pocket Seafood Watch guide when perusing the fish counter at their local grocery store to make sure they’re choosing something that is a) sustainable, b) not filled with toxins, and c) something they know how to cook.

One of the developments in the 21st Century seafood industry, for better or for worse, is the growing market share that farmed fish represents. But are farmed fish sustainable? What makes one farmed fish a more responsible choice than another, or than a wild caught fish? Our guest today on Sea Change Radio is Josh Goldman, the CEO of Australis Aquaculture, the world’s largest producer of Barramundi, or what the company calls “sustainable sea bass.” Goldman walks us through innovations in aquaculture and tells us everything we’ve always wondered about fish farming – from why there aren’t any tuna farms to whether the all-powerful Japanese seafood industry is finally coming around to more responsible production practices.

To close the show, Sea Change Radio host Alex Wise reads an excerpt from Yale Environment 360 about the ongoing struggle to transform the Japanese seafood industry.

Rock & Droll: Chuck Leavell and “Rep.” Jack Kimble

ChuckLeavellJackKimbleThis week on Sea Change Radio we hear from two very different guests. First, it’s rock and roll legend, conservationist and environmental author, Chuck Leavell. He has played keyboards for the Rolling Stones since 1985 and is also known for his work with artists ranging from The Allman Brothers Band to Eric Clapton to The Black Crowes. Leavell talks to host Alex Wise about the ins and outs of his stellar career as a musician, his founding of the Mother Nature Network, his tireless work for sustainable forestry, and whether or not Alex’s favorite children’s story has a pro-environment message.

Next, Sea Change Radio takes a sharp right turn into the mythical 54th Congressional District of California with ersatz “Representative” Jack Kimble. Like some other members of Congress, Kimble does not let his abject ignorance stand in the way of strong opinion. You may find the interview puts you in mind of Lord Byron’s quote, “Fools are my theme, let satire be my song.”

Robert Boyd on the Hydrogen Economy

RobertBoydOne of the most alluring answers to the climate change conundrum is a transition from a fossil fuel-based economy to a hydrogen-based economy. As hydrogen power technology continues to evolve, it certainly seems like a promising way to decarbonize our energy system – but what are the practical considerations? Unlike carbon-based energy sources, there are no natural reservoirs of hydrogen on the planet; moreover, it must be bound to a carrier like natural gas or water. HydrogenThis week’s guest on Sea Change Radio is hydrogen vehicle fuel technology expert, Robert Boyd. Boyd and host Alex Wise discuss this relatively clean and plentiful resource, and what he and others are doing to help get us over the production and distribution hurdles that stand between us and a shift to a hydrogen-based economy.

Zac Unger: Looking Polar Bear Endangerment In The Eye

ZacUngerWe have all seen the mournful image of an unhappy polar bear isolated on a melting ice floe. It conveys the doom of that one bear as well as his species, and implies that we are all headed in that direction if something is not done about global warming.

Inspired by such images and his commitment to ecological conservation, this week’s guest on Sea Change Radio, Zac Unger, ventured up to the great white north to check out the plight of polar bears himself, up close. What he found surprised him. Embedding himself with scientists, Unger learned about how the bears are adjusting their diet, fasting periods and even breeding behavior in response to the warmer, longer summers that climate change is bringing. These adaptations, in conjunction with hunting prohibitions instituted late in the 20th century, have allowed the polar bear population to flourish. Continue reading
