Okay okay, just one more. . .
"We have shown that while genetic engineering has provided a solution to the problem of viral diseases, there are also these unintended consequences in terms of additional susceptibility to other diseases."
Creating new varieties of plants doesn't make a perfect plant? Shocking.

Death by Deforestation
"We modeled the worst and best case scenarios: 100 percent deforestation in the Maya area and no deforestation," says Sever. "The results were eye opening. Loss of all the trees caused a 3-5 degree rise in temperature and a 20-30 percent decrease in rainfall."

The Failings of Herbicides
"The development of herbicide-tolerant crops has played a role in the growth of megafarms of 10,000 plus acres. That amount of land can’t be farmed unless you’re doing it from atop a sprayer and a combine. But dealing with pig weed now involves putting workers out in the fields to pull weeds by hands—pig weed is sturdy enough to “stop a combine in its track” according to the ABC News report. Handweeding isn’t feasible for these massive farms, which is why thousands of acres of land devoted to commodity crops are being abandoned in the face of the superweed onslaught.
"The Rodale article observes that mechanical cultivators—once considered an old-fashioned and outmoded approach to weed control—are making a comeback in the South as “steel in the field” becomes important again."

The Perennial Wheat Project on NPR
"It's taken DeHaan years and years, but as we look around the greenhouse today, we see the result of his work: hundreds of plants, sitting on waist-high benches, that are a cross between wheat and grasses that grow year-round.
"DeHaan will soon plant them in the fields. He hopes that maybe — just maybe — up will sprout a wheat plant that produces lots of grain and actually tastes something like wheat, and has the hardiness of a native prairie grass."
Another little article here points out another potential bonus of perennial wheat:
"Perennial wheat could potentially offer farmers increased flexibility where the crop can be grazed and then harvested. "

GMO Crops Versus Organic
My take on GMO crops is not that GMO crops have anything inherently wrong with them. It is the lack of testing of these products that scares me. Monsanto actively squelches testing of its products. Also, varieties of plants that are created to be doused in more pesticides rather than less – yuck. And there’s the horrifying trend towards GMO-makers suing organic farms to death when the GMO pollen contaminates the organic crops. While genetic modification could be used to improve the world’s food supply safely, it is instead being used to earn its makers as much money as possible, while not addressing long-term problems.
There are also issues not just with GMO crops, but with conventional agricultural practices in general: the land has been so energetically plowed, and plowed, and plowed again, that there is no longer significant worm, insect, or fungal life in the soil. Monoculture farms displace and kill larger life-forms. Erosion is a huge problem, both for the farm’s productivity and through pollution of water downstream. And in conventional practices, the depleted nutrients in the soil are replaced with additives of nitrogen, phosphorous, and potassium, but lesser nutrients aren’t added back to the soil, and therefore don’t end up in our food.
Due to these problems, our current agricultural model is unsustainable. If modern agriculture (GMO companies included) don’t step up to address these problems, then organic farming will be the only option left.

Birds of Prey in Wrentham
This is a Broad-winged Hawk named Rufus, and his extraordinary keeper, Marla Isaac. Marla rescues and rehabilitates animals with New England Reptile and Raptor. Last weekend the Open Space Committee of the town of Wrentham hosted Marla and six of her magnificent birds in an educational and riveting demonstration of native New England birds of prey.
Even knowing ahead of time that the presentation would include owls, it took my breath away to see an actual owl sitting on a human hand. This is a Barn Owl, whose name I didn't catch.
As Marla presented each bird, she walked around so that everyone could get astonishingly up close and personal. We had the best seat in the house: a picnic blanket right up front. Chris stood against a tree and snapped photos the whole show while I minded Gabe. I had to take my little munchkin aside to keep him busy during the first half of the presentation, which was all talk; but once the birds were brought out of their boxes, I scurried back to our seat.
Each time she walked a bird past our blanket, I could swear the birds stared down at my son with a look that said "tasty!"
Merlin's egg was rescued from a tree that had been cut down. Because Marla was the first thing he saw on hatching, he is imprinted on her - which means she's a big mama owl to him.
This is "Sargent", the fastest animal on Earth: a Peregrine Falcon. It surprised me how small he was. These birds are as flawless-looking as airplanes.
This gigantic bird is a Red-Tailed Hawk. You can see his red tail feathers more clearly in the next photo:

. . .and this eerie beauty is "Uncle Fester" the Turkey Vulture.
And now for some flying! Rufus, the little Broad-winged Hawk in the first photo, was turned loose for some aerial fun. Here, he is diving after his favorite toy. If cats had wings, they would play in this manner.
Marla understands what motivates her birds. It's unsentimental: they use her for food.
Here, Rufus gets some quail. He gulped an entire leg-bone like a carnie swallowing a sword. These birds require the equivalent of entire quail each and every day.
Before filling the raptor's belly with raw meat, bones, and feathers, Marla sent Rufus flying back and forth to perches strategically placed throughout the audience - including one almost directly behind me. I had the amazing experience of watching a hawk fly almost straight towards my face. It took a concerted effort not to duck. Rufus passed so close that I was buffeted by the wind he stirred.
Rufus did some guffaw-worthy hops about the area, including comical slippery landings on the smooth tops of the bird boxes.
Here, he flutters unexpectedly to a playground structure.
This boy had an encounter that he'll undoubtedly be talking about for the rest of his life.
