Have you ever wondered why we keep putting off for tomorrow what we can do today, particularly when it comes to the issue of, yes—I’ll say it—global warming? Quite apart from the flat-earth crowd, the people who believe the overwhelming scientific evidence tend to acknowledge a need to do something about this existential threat. But, particularly here in the U.S., we continue to buy gas-guzzling cars, pickup trucks and sport utility vehicles, all for the sake of comfort, or status, or some weird need to project machismo.
Conversely, to their credit, aircraft engine and airframe manufacturers have reacted to customer calls for fuel efficiency, albeit all in the name of cost savings and, by extension, profits. The problem remains, however, that we simply don’t have the time to let the free market take care of the problem. If we don’t do something fairly dramatic now, according to most scientists steeped in the subject, we’ll reach a sort of tipping point at which nothing will stop the cascade into what reasonable people would consider a natural disaster.
