All leisure, travel and sports activities are not necessary so to most people, it seems like they are just levels of the same thing. Car racing, jets(travel), luxury yachts, speed boats, quads, 4×4 trucks, helicopters are all high fuel use so where do we draw a line. Over consumption and waste are real issues but high fuel use is only an issue if you believe the advocacy around CO2. People are gradually catching on that the Climate Change issue is much more than just science and physics. They also have to believe in the input assumptions and theories and the projections from climate models and then impact forecasts from notoriously unreliable economic models. Even if you believe the warming disaster forecasts, it may take much less GDP and be better for the environment and the economy to adapt to the warming versus spend trillions and cripple the economy to try control climate by reducing the increase in CO2.
What if we waste all that money and debt and it turns out that the warming is all due to natural causes?
