CONSERVING PROTECTED WILDLIFE SPECIES BY KILLING OTHERS
But now, in spite of the ESA and the conservation measures it imposed, the spotted owls are still not doing as well as hoped, and the finger is pointing at the barred owls. The question being asked: should humans intervene in the struggles of nature by killing one species to save another? Some experts and conservationists think that the barred owls are expanding into spotted owl habitat because of human-induced changes in forest habitat. Their conclusion is that further manipulation of nature is therefore justified.
This is not an easy question resolve, and it is not the only situation in which killing one kind of animal to save another is accepted. In the lower Columbia River (the border between Oregon and Washington), federal and state authorities have justified killing California sea lions because they eat too many salmon and sturgeon (see my previous posts - you can search this blog - in which I interviewed Sammy C. Lyon).
So where does this end? I mean, there are a lot of situations where some species of wildlife are killing other, protected species of wildlife. Take a look at the nesting colonies of double-crested cormorants and Caspian terns in the Columbia River estuary, for example. Last year, the estimated 23,000 adult birds and their chicks in these two nesting colonies are estimated to have eaten about 25 million juvenile salmon, including those listed as threatened or endangered under the ESA (http://www.cbbulletin.com/402325.aspx). Holy cow - break out the machine guns!
Maybe it's a good thing humans are the top of the food webs on this planet. Imagine, if you can, some higher form of life in the galaxy that has an inter-galactic Endangered Species Act, administered by the IEPA (Inter-galactic Environmental Protection Agency). And imagine, again if you can, IEPA staff stops by Earth for an inspection, and finds that the activities of Homo sapiens are causing the extinction of many, many other species. You know, things like over fishing; over cutting forests; building roads, dams, and cities; polluting the air, land and water; changing the climate; and etc., etc. Uh oh, open season on human beings!
But seriously, this is a tough one. One of the basic laws of ecology is that everything is connected to everything else, meaning that everything we humans do has some consequence. Are the actions of humans unnatural because they have negative effects on what we have labeled "natural?" Or is everything we humans do part of the natural order of things because we are, after all, a species of wildlife on planet Earth? (This means, of course, that nuclear weapons are natural!)
It's a conundrum.

WTF SARAH-MICHELLE PALIN-BACHMANN?
WORLD HISTORY LIVE: TUNISIA, EGYPT AND MORE
But all of that is another story. The very important story here, one that I didn't know, is about the people of Tunisia and their government. I didn't know anything about the Tunisian dictator until the people chased him out. I didn't know that Tunisia has a constitution that prescribes how a President is succeeded and how and when elections are held. I'm beginning to understand this now, but more importantly, I also understand that a successful democratic movement - a mostly peaceful revolution, if you will - will be a major event in history because of the precedent it will set among the Arab countries.
And so I try to follow the unfolding events in Tunisia. I look for news articles in the NY Times and other sources, and I've found a Facebook page "Support Tunisia" to which people are posting their experiences, analyses and opinions.

THE CHINA PROBLEM
The writer and activist Liu Xiaobo has just been awarded the Nobel Peace Prize, and it's likely that he won't know about it because he is in jail in China. The award is certainly a political statement by the Nobel Committee intended, in part, to highlight the human rights abuses by the Chinese government. China, as I've written here previously, is a complex place that is on the one hand making great advances for it's people while also continuing to be in many ways a totalitarian and oppressive place. Mr. Liu has been jailed, again, for his activities promoting democracy and personal freedoms. Sunday, September 26, 2010

WHY I DRIVE A ZAP ELECTRIC "CAR"
"Three wheels, six batteries, one extension cord, no gas tank!" That's what I say when asked about my pickup truck. A lot of people think it's "cool," and some, mainly my sons, find endless ways to make fun of me because of it. Even grandson Jake calls it the motorcycle with training wheels.

LIFE'S A BEACH, AND CONTEMPLATIONS THEREON

I find myself, again, standing at the edge of the water looking into and over the waves crashing towards me. I am humbled by the enormity of the ocean, and knowing something about it's complexity of physics, chemistry and biology makes me feel even more insignificant. I am but a speck on the vast edge of the sea, occupying much less area than a singe pixel of a satellite photo on Google Earth. That is tiny.
This overwhelming sense of awe and wonder washes over me when I walk the beach, just as the waves dying on the sand wash over my feet. It ebbs and flows, filling me with wonder at one moment, joy the next, then sadness born of the realization that I am merely an animal whose life is less than the blink of an eye in the scale of this world. I don't completely understand the sadness part; I think it's because I am so naturally curious, so filled with a thirst for knowledge, and knowing that I won't be here long enough to figure it all out.
I always stop and watch the sand in that zone on the beach where waves wash over it. A seemingly random set of patterns actually makes sense if you stop and watch for awhile. The water mobilizes the sand grains and the things mixed in with them; bits of rock, shell, wood, leaves and tiny living animals. As the water recedes, these things sort out by size, shape and density, except for the living animals - they seek shelter until the next wave. The resulting patterns are beautiful art works by nature (although, I know that "art" is something I can label because I'm a human).
The last time we were on this beach, I brought a small net and held it in the water as a wave receded. When I emptied the net into a bucket of water, the water came alive with tiny transparent animals, a kind of shrimp (Mysids, to be geeky about it). You can't see them when you watch the water swirling around your feet, but they are there by the thousands, along with other animals who make their living in the surf zone of the beach. Here's a photo of Mysids taken with the digital microscope I also brought last time (yep, more geekiness).

And then there is sand. Amazing stuff, sand. How many grains of sand are on the beach? We sat in the sand today, and I let hands full of dry grains sift through my fingers, trying to imagine how many there were. I looked at this photo I took of sand grains last time we were on this beach (yes, the digital microscope again).
According to the scale in the photo, a grain of sand on this beach is approximately 0.25 millimeters in diameter. A quick calculation, and I came up with this number: one cubic inch of sand from this beach has somewhere around 1,061,208 grains of sand. Each of these grains of sand was part of molten rock deep within the planet millions of years ago, came to the surface and formed land, was eroded or broken loose and carried by wind and water ultimately to the ocean, where it was cast upon the shore for me to walk and sit on. Talk about feelings of insignificance!
I am amazed, and again greatly saddened, by the fact that the human species has now altered the physics, chemistry and biology of the world's oceans. I'm not talking about the oil spill in the Gulf of Mexico. I'm talking about the effects of unbridled dumping of chemicals and trash into streams, rivers and oceans; emissions of climate altering carbon into the atmosphere; wanton depletion of stocks of fish. I could go on, but suddenly, I don't feel so insignificant anymore.
