    Sure globalization is great if you ignore the niggling minor problems
    like pollution and exploitation of desperate workers.

    I find it hard to call something "exploitation" when people are voluntarily
    flocking to these allegedly horrible jobs. If they really felt exploited, they
    could always go back to subsistence farming. The fact that they don't is
    evidence that subsistence farming is worse than just about any "exploitative"
    industrial job.

    Also you would have to arbitrarily decide that dying from chronic
    diseases from living older is better than dying younger from acute
    diseases.

    Neither "you" nor I need to arbitrarily decide this at all. Clearly, when given
    the choice, people choose the former. How many people let their children die of
    an acute but preventable disease and say "well, at least she didn't have to
    worry about dying of cancer at 90." I'm guessing the answer is "not many."

    And of course since there is no objective way to measure quality of life
    we'll just assume that people with the most stuff are the happiest.

    The simplest thing to do is give people the option to choose what makes them the
    happiest. Who are you or I to tell someone what their quality of life should be?

    It validates the American lifestyle so Americans, at least, have to
    approve to avoid cognitive dissonance. The best thing any government could do
    would be to eliminate the formation of "for-profit" corporations.

    You do realize that you are typing on a computer made by a for-profit company,
    which is processing the characters using a CPU made by a for-profit company,
    which are being sent over a network adapter (wired or wireless) made by a
    for-profit company, over a network of networks operated (largely) by for-profit
    companies, to a website owned and operated by a for-profit company (GKNT on
    NASDAQ), which stores your comment on servers made by for-profit companies. They
    certainly have their faults, but Moore's law is not driven by love or
    solidarity, it's driven by companies relentlessly competing to steal each
    other's consumers, benefiting all of us in the process.

    Their "it's all about the profit" charters have made them a danger to the
    planet. They have used globalization to avoid doing the right thing
    environmentally and socially.

    So modern medicine, housing, culture, food and plumbing are all "avoid[ing]
    doing the right thing" socially? What on earth would the "right thing" be?

    They have no conscience because no one in a corporation feels personally
    responsible for the negative impacts of the company.

    Is it really meaningful to say that anything other than an individual has a
    "conscience?" Plus, why is having a conscience so seemingly critical for a
    company? If a company consistently does things that people don't like, and there
    are better alternatives, that company will go out of business. It happens all
    the time, even for the giants.

    As they say: "It's not personal, it's just business".

    Of course, ripping people off and being a dick is bad, I think we can agree on
    that. But to a large extent, this is a feature, not a bug. There is just no way
    you could support the number of people there are if all interactions had to be
    "personal." The human brain simply lacks the capacity to form personal
    relationships with a few thousand people, let alone 7 billion (or whatever the
    population is these days). Having to interact with strangers is simply a fact of
    modern life that is inseparable from all of the other wondrous benefits it
    brings.

    Globalization is really a corporate phenomena that takes advantage of
    foolish people who would rather chase what they want rather than what they
    need.

    Again, who gets to decide what someone "needs?" I'd say, let the individual
    decide what he or she needs. After all, that person is in the best position to
    know what he or she needs or wants.

    According to Wikipedia:

    There is as yet no satisfactory scientific explanation as to why chlorophyll has evolved to "ignore" green and near-green light, which are a major part of the visible spectrum.

    It could be that specific chemical properties of chlorophyll make it more expensive (in terms of the amount of energy required to produce each molecule) to synthesize green-absorbent light is greater than the marginal increase in energy produced. It could be that the current structure of chlorophyll is at a local maximum for efficiency, and that evolving an alternative molecule would require first using a much less-efficient molecule and then improving from there. Evolution and evolutionary processes are great at finding local maxima, but can completely miss higher maxima further away.

    As far as "why green?" I imagine that if and when we know why chlorophyll ignores green light, the answer will be something like, "green-ignoring photosynthesizing pigments out-competed the other photosynthesizing pigments because of reason X, and alternative colored pigments are different enough from chlorophyll that photoautotrophs have not jumped to using those alternatives."

    The answer to "why reason X?" likely has something to do with the difficulty of the organic systems at the time to produce pigments more efficient than chlorophyll relative to the energy return of the increased efficiency.

    Ultimately, some of the "why" depends on the specific emission spectrum of sunlight received at ocean level on the Earth, which is determined by the size and composition of the Sun and the composition of the Earth's atmosphere. The "why" of that is because of the random scattering of interstellar dust which eventually became our solar system. I guess, if you really wanted, you could place some idea of a supernatural being or force there, saying,

    god(s) arranged the chaotic interactions of interstellar dust such that one particular blob of dust formed into a G2V-class star with a black body temperature of 5777 K, then seeded one particular planet (through the tendency of certain elements to cluster around Earth as opposed to Mars or Venus, as well as bombardment by asteroids) with a mixture of elements such that a certain kind of organic life arose which evolved photoautotrophs which, because of the relative abundance of certain elements, the relative presence of various wavelengths of light at sea-level, the photosynthetic efficiency of different pigments, and the energy and cellular machinery required to produce said pigments, chlorophyll, which does not efficiently absorb green light, ended up becoming the dominating pigment used in photosynthesis. And that is how god(s) made the grass green.

    In other words, a "god(s) of tweaking things at the margins," which doesn't exactly fill me with awe. Plus, given the sheer size of the universe, it's easy to believe that our planet and everything about it arose out of dumb luck.

    Why would both parents need to acquire a trait at the same time? Either parent could pass on the trait, and beneficial traits would tend to spread throughout the population. More complex traits don't need to arise all at once, so a beneficial trait could arise in a small segment of the population and then gradually spread as those possessing the trait out-competed those without it.

The primary defining characteristic of all life is organizing. The most basic function of a cell is separating the interior from the exterior; when a cell ceases to segregate internal from external, it is no longer alive. Life is, literally, the organization of simpler compounds into organs, cells, and populations.

    There is no real answer to these questions, since they all depend on such subjective opinions of what constitutes a human or "potential human." Since it will always be arbitrary, we choose an arbitrary point at which to make the cutoff, birth being an unambiguous one. The problem I have with moving the cutoff earlier (and especially within the first trimester) is that it then include morning-after pills and intrauterine devices, since they act after fertilization, but prevent implantation (well, for morning-after pills, it seems like the research isn't completely settled on that point).

    I doubt the whole world will move to highly fault-tolerant or failure-oblivious computing any time soon, but it could be an interesting niche for a coprocessor, and/or in certain domains.

    Well, you're right, but "I can show you two power plants" is not a good argument. It's fairly easy to take a look at the DOE list of US electricity sources to see that we get (as of 2009) 48.2% of our energy from coal, 1.1% from petroleum liquids and "petroleum coke" (whatever that is). Another 21.4% comes from natural gas, which I guess could be considered oil, but usually is in a separate category.

    It would definitely be accurate to say that most of our energy comes from fossil fuels or non-renewable resources, but we actually only get a small amount of our electricity from oil.

    Spot on.

    I would like to add that the other thing that people tend to forget is that subsidies don't just magically appear out of thin air, that money comes from somewhere. If the government spends $1 trillion per year (which is about how much the oil subsidy is) less on oil and gas, that's $1 trillion which can be spent on other things (or deducted from taxes, though I can't imagine the government just giving that money back).
