War: What is it Good For?
That’s were man comes in.
There are over 6 billion humans on earth, and I read just yesterday that demographers project a human population of 12 billion by 2050. I think that 6 billion is probably already too many. I can’t imagine the stress that a population twice that size will place on the Earth. As we have seen time and time again in nature, a species in an environment with no natural predator tends to reproduce without impediment. But perhaps we do in fact have a natural predator that no one really considers.
Ourselves.
From the beginning, human history has been riddled with violence. So much so, that the study of history is often tracked by the occurrences of war. War is the primary focus and everything else simply goes to explain what happened after the last war and what lead up to the next one. It is not uncommon for hundreds of thousands of people to be killed over the course of a single war. I can’t think of anything else that even comes close to claiming as many lives over a comparably short period of time. Small fish eat plankton, big fish eat smaller fish, bears eat big fish, and then humans make coats and rugs out of bears. We’re at the top of the food chain. Aside from the occasional shark attack, dog mauling or unfortunate encounter with a cannibal, humans don’t get eaten by anything else, but that doesn’t mean that we ourselves aren’t preyed upon. We’re the product of our own ambition, greed and pride. We wage war for the accumulation of wealth and power, and one could argue that as a result, we provide a valuable service to nature. By taking on the responsibility of reducing our numbers, we have managed to maintain a rough balance with other populations on earth.
Perhaps in the grand scheme of things, war is actually good for something.

Nuclear Fusion
The only problem is that they haven’t quite figured out how to do it yet.
The EU, US, China, Korea, Japan, Russia, and maybe others, have pledged $11 billion to build the International Thermonuclear Experimental Reactor, an experimental plant which will be located in France to make the theory of nuclear fusion a reality. If I remember correctly, they hope to prove that nuclear fusion is viable within the next 10 years and then make it commercially available by 2050.
2050 is still a ways off, but if this thing works the way scientists hope it will and big polluters like the US, China, and the EU take concrete steps to curb global warming in the meantime, maybe mankind isn’t doomed after all.

The Rebirth of the Electric Car??
However, in a move that I believe caught many people by surprise, GM unveiled at the recent Detroit Auto Show the Chevy Volt , an electric-gasoline hybrid that could be available as early as 2010. Of course, the Prius has been around since 2000, so what makes this hybrid any different? Well, unlike the Prius or other hybrids currently on the market, the Chevy Volt could potentially run forever without using a single drop of gasoline. After charging the battery at home for 6 hours, the Volt can go 40 miles on battery power alone. GM asserts that the majority of Americans live within 20 miles of work, so if that's the case, a normal weekday commute could be done completely using battery-powered electricity. When in fact a person needs to drive more than 40 miles without re-charging the battery, a three-cylinder engine kicks in to burn fuel to recharge the battery, potentially boosting fuel economy to 150 miles per gallon! Furthermore, the engine is equipped to burn E85, which is 85/15 ethanol/gasoline mix. The use of E85, they claim, would mean that the car could go over 525 miles per gallon of petroleum. While there are still some concerns surrounding the efficiency of ethanol production in the US, I imagine that if the ethanol technology in the US isn't able to meet demand at an acceptable price, we could potentially import ethanol from more efficient (and friendlier) nations, such as Brazil, until we could rely solely on domestic production.
Given the decades of neglect and self-interest in terms of environmental sustainability, I hope that 2007 will see a growing trend towards greener business, the likes of which we first began seeing on a significant scale in 2006.

Oceanic Carbon Sequestration
Expected High Tomorrow: 66 degrees
While I am definitely enjoying the very mild winter here in New York this year, I can't shake this sinking feeling that 5 or 10 years from now science and society will look back at this winter as a major point in the progression of global warming. Columbia University economist and director of the Earth Institute Jeffrey Sachs argues that the global ecosystem acts as a "step function". In much the same way that a bathtub can continue to accept water without any ill effects until suddenly the water reaches the top and begins to overflow onto the floor below, the earth's ecosystem can accept continuous environmental stress until one day it reaches its limit and begins to rapidly deteriorate. I worry that this winter of near record-breaking warm temperatures here in the northeast is signaling that the bathtub has begun to overflow.
Fortunately, however, there are some very intelligent people out there working on some very new ways of turning back the clock on global warming. One interesting path of research is carbon sequestration -- pulling carbon dioxide from the atmosphere and burying it deep underground. While scientists are still working on ways to actually make that a reality, one economist/inventor, Philip Kithil, thinks he has a way to sequester carbon in our oceans to the ocean floor. As reported in the Guardian , there is a "barrel-shaped type of plankton called salps, which feed on algae and excrete dense pellets of carbon that sink to the ocean floor." By using a system of plastic tubes installed throughout the ocean, Kithil argues that colder, nutrient-rich water can be pulled from the deep ocean and brought closer to the surface to promote a suitable environment for algae. With the abundance of algae, the salp plankton will begin to flourish and through their biological processes, naturally sequestering carbon from the surface down to the ocean floor. Furthermore, Kithil believes that once the systems of tubes are in place, their output could be accelerated in order to further cool the surface water ahead of incoming hurricanes, which strengthen as they move along warm water.
The downside, of course, is that all of this is going to cost hundreds of billions of dollars, but I figure if the US alone can spend over $300 billion on losing a war in Iraq, I think that the global community can scrape together enough money to make innovations like this a reality.
Let's face it: if we mess up this planet, we don't really have anywhere else to go.

The Highlights
The Reluctant Environmentalist
Bush: The American people expect us to reduce our dependence on foreign oil and increase our use of alternative energy sources. So we must step up our research and investment in hydrogen fuel cells, hybrid plug-in and battery-powered cars…
a. tyrell: If you take a look at the film “Who Killed the Electric Car” you’ll see that not only is the electric car possible, but we already have the technology for it. And I’m not talking about those funny-looking one-seater cars you see on prototype car tests on TV. These are completely regular looking electric cars that regular people owned and used during the early 90s until the auto industry decided that they wanted to take them off the market.
A Bit of an Understatement
Question: Mr. President, less than two months ago, at the end of one of the bloodiest months in the war, you said: Absolutely, we're winning. Yesterday, you said: We're not winning; we're not losing. Why did you drop your confident assertion about winning?
Bush: …My comments yesterday reflected the fact that we're not succeeding nearly as fast as I wanted, when I said it at the time, and that the conditions are tough in Iraq, particularly in Baghdad.
…Victory in Iraq is achievable. It hadn't happened nearly as quickly as I hoped it would have. I know it's -- the fact that there is still, you know, unspeakable sectarian violence in Iraq, I know that's troubling to the American people.
A Remorseful President
Question: Mr. President, Lyndon Johnson famously didn't sleep during the Vietnam War; questioning his own decisions. You have always seemed very confident of your decisions, but I can't help but wonder if this has been a time of painful realization for you, as you yourself have acknowledged that some of the policies you hoped would succeed have not. And I wonder if you can talk to us about that. Has it been a painful time?
Bush: Most painful aspect of my presidency has been knowing that good men and women have died in combat. I -- I read about it every night. I -- my heart breaks for a mother or father or husband and wife or son and daughter. It just does. And so, when you ask about pain, that's pain… But the most painful aspect of the presidency is the fact that I know my decisions have caused young men and women to lose their lives.
Alternative Energy
Bush: nuclear power is going to be an essential source, in my judgment, of future electricity for the United States and places like China and India. Nuclear power is renewable, and nuclear power does not emit one greenhouse gas. And it makes a lot of sense for us to share technologies that will enable people to feel confident that the new nuclear power plants that are being built are safe, as well as technologies that'll eventually come to the fore that will enable us to reduce the wastes, the toxicity of the waste and the amount of the waste. Continue to invest in clean-coal technologies. Abundance of coal here in America. And we need to be able to tell the American people we're going to be able to use that coal to generate electricity in environmentally friendly ways. My only point to you is: We got a comprehensive plan to achieve the objective that most Americans support, which is less dependency upon oil.
a. tyrell: If he’s as concerned with alternative sources of energy and decreasing US dependency on foreign oil as he says he is, what has he been doing in this regard for the last 6 years? I can’t think of a single significant measure proposed by the Bush Administration that was primarily in support of alternative sources of energy. There has been some support for hydrogen fuels and ethanol derived from corn, but given the predicted impracticality and prohibitive expense of hydrogen fuel and the glaring inefficiency of US ethanol production initiatives, I would suspect that support for these technologies has less to do with the environment as it does with covertly protecting agriculture and private industry.
Social Values
Question: …Mary's having a baby. And you have said that you think Mary Cheney will be a loving soul to a child. Are there any changes in the law that you would support that would give same-sex couples greater access to things such as legal rights, hospital visits, insurance, that would make a difference, even though you said it's your preference -- you believe that it's preferable to have one man-one woman...
Bush: No, I've always said that we ought to review law to make sure that people are treated fairly…
a tyrell: What about support for the Constitutional Amendment to ban gay marriage? I wouldn’t view that as a measure that would ensure that all people are treated fairly.
Where’d that surplus go again?
Bush: My message to the Iranian people is: You can do better than to have somebody try to rewrite history [referring to Iranian President Ahmadinejad]. You can do better than somebody who hasn't strengthened your economy…
a tyrell: So I’m still unclear on how President Bush has strengthened our economy. Was it through tax cuts to the rich that led to huge corporate profits, but virtually no growth in wages and very little job growth until fairly recently? Or was it by spending $300 Billion in Iraq over the last 3 years while we continue to fund our deficits by borrowing from China and other nations?
So if the Iranians deserve better, does that hold true for us too?
