Today I'll take the other side of my last blog and assume that excessive release of carbon dioxide or other greenhouse gases is not the root cause of global warming. Indeed many would argue that this is a fair assumption.
I still believe that it is a good idea to be vigilant of our consumption of fossil fuels and control the amount of CO2 emission. Doing so helps us in at least two ways: reducing foreign dependence on oil and reducing health risks.
I don't live in the Middle-East and do not support being dependent on them. We've all heard the argument and know the implications - depending on others for a resource as vital as crude oil is simply a ticking time-bomb. Rather, if policies encourage the research and the use of alternatives to crude oil, not only does it decrease aggregate demand (and possibly price assuming the cartel does not also cut supply drastically), but it also reduces the emission of CO2 amongst other gases that pose a longer-term health hazard. Have you been to Los Angeles or perhaps seen the air above a major city during the day, for instance during take-off or landing on an airplane? The revolting sight of brown smog will be enough to change your mind on our love affair with burning fossil fuels.
