Green Options

Bighead carp are one of two non-native species of Asian carp causing widespread concern among Great Lakes advocates. The other is silver carp.

Great Lakes advocates are calling it a “conservation emergency” now that non-native Asian carp have been detected within seven miles of Lake Michigan. They want an immediate closure of locks and gateways leading to the lake in a literally”last-ditch” attempt to keep the fish out.

The fear is that the giant fish will disrupt the valuable Great Lakes sport fishery by outcompeting species at the top of the Lake Michigan food web, consuming the forage fish the established species depend on — and like many of the other 180 non-native aquatic species already in the Great Lakes, causing general ecosystem disruption.

Writing for GreenOptions I sometimes get contacted by PR firms wanting to promote projects. Sight unseen I usually shrug them off, I happen to only write about items that I have seen or used, and can feel good about endorsing. When MSNBC contacted me the other day with a preview of a new special on animal conservation, I figured it was probably more of the same stories I have seen over and over again. However, when I watched the preview it sucked me in. It is hosted by Jeff Corwin, a famous naturalist you have probably seen on TV. I can say wholeheartedly that this looks like something that I can feel good about endorsing.

Every 20 minutes a species will go extinct, 20,000 species this year, and this Sunday, November 22, 8PM Eastern MSNBC will be airing “100 Heartbeats” hosted by Jeff Corwin to fight back. You can watch the preview here: http://www.msnbc.msn.com/id/21134540/vp/33490448#33490448

There is a lot of confusion and disinformation circulating today about seeds and the ethics of their commercial sale.  Actually a healthy, commercial seed industry is critical for agricultural sustainability.  Because seeds are such a fundamental component of the sustainability of our food supply, this area deserves careful thought and accurate information even if you are never going to farm or even garden. I’ll try to address some of the modern “myths” about this.  I’ll talk about “farmer-saved seed,” and “hybrid seed.” In a later post I’ll talk about “GMO seed,” and the mythical “Terminator Technology.”  But first a little history.

Seed-bearing plants start showing up in the fossil record ~350 million years ago, first as gymnosperms like cycads, conifers… and eventually, flowering plants (angiosperms) like most of the living plants today.  Other than pine nuts and sea weed, I can’t think of any crops that are not angiosperms (Contest! - 5 virtual sustainability points to someone who can come up with another non-angiosperm crop plant)

Jarrod Diamond’s wonderful book, “Guns, Germs and Steel” talks about how the initially accidental and later intentional collection and planting of seeds is what made human civilization possible - the move beyond the hunter/gatherer state that happened about 10,000 years ago in the “fertile crescent.”

In 2007 federal protections were dropped for the protection of Yellowstone grizzlies. Ever since then, the Greater Yellowstone Coalition have been fighting to give protection back to the bears. They argued that the U.S. Fish and Wildlife Service (FWS) failed to address the loss of essential food sources for the bears, whitebark pine seeds and cutthroat trout.

On Monday, September 21 they finally achieved what they were fighting for when Judge Donald Molloy ruled that inadequate regulatory mechanisms were put in place to manage the bears. The Natural Resources Defense Council (NRDC) and six other groups, represented by Earthjustice, have a similar case pending in Idaho.

Environmental care is a practical, worldly thing. But it is also a step in one’s personal evolution. On the one hand, it is a practical response to the environmental problems we are facing. It is also a foresighted response to the issues (economic and environmental) that we might be facing if we don’t think more about the environment we live in and rely on. But, on the other hand, it is much more than that.

According to reports, 13 cheetal and one swamp deer died Friday evening under “mysterious circumstances” at the Kanpur Zoo.  Viscera samples and stomach content have been sent to the Indian Veterinary Research Institute (IVRI). Results are expected sometime within the next two weeks.  The samples will also be tested at the Lucknow forensic science lab to rule out “sabotage.”  

Communities of all sorts are being disturbed by the fires in California. As another result of climate change, bird communities are expected to see some big changes in other ways, according to a new report released on September 1.

An expert advisory committee this week released recommendations on restoring Minnesota’s dwindling moose population, whose decline one expert said is related to gradual warming of the state’s climate. “The moose, of course, is not an animal that deals very well with heat,’’ panel chairperson Rolf Peterson of Michigan Technological University said. “We wouldn’t even be here today if it wasn’t for climate change.’’

PacRim Coal’s plan to strip mine coal right through 11 miles of salmon-bearing streams in Alaska would destroy critical wetlands and headwater streams beyond the point of restoration, according to three new studies by scientists.

The salmon fisheries along the Chuit River would be severely damaged, so much so that the researchers say that restoration would be “virtually impossible”.

If you could declare a home town of evolution it would be the Galapagos Islands. Back in 1835 a sea sick young naturalist, Charles Darwin, landed on the Galapagos to conduct a little research. That research was the genesis of Darwin’s seminal work “On the Origin of Species by Means of Natural Selection.” Darwin was inspired by the grand variety of animals filling specific niches on the islands.

Now tourism is threatening to wipe out the animals which inspired one of the most important works in all of science. This time, for once, humans are not the main bad guy in this story. Although, as often the case, humans are involved unwittingly. When humans visit the island, they don’t realize they are bringing along a stowaway. Mosquitoes. The oft-maligned disease ridden scourge of the world.

This picture is a picture of the beautiful Monterey, California coastline. This is where I grew up. It is famous for it’s beautiful sea life. Sea otters, jelly fish, sea lions, kelp forests all populate the Monterey coast.  The Pacific Ocean is the largest ocean in the world. Yet, with all that mass of water, we humans are changing the chemical properties. The acid levels in the pacific ocean, as well as every ocean around the world, are rising. If things keep going this beautiful coastline, my home, will become a wasteland of acid. Habitable to only the most extremophiles.

Rewind our story. Fossil fuels are not just a problem for our atmosphere. When we burn fossil fuels carbon dioxide falls down into the sea. The carbon dioxide is quickly converted into carbonic acid. Carbonic acid has been known to be corrosive to corals and shellfish, and now scientists are discovering that rising acid levels in the ocean are effecting other animals as well.
