significantly reducing air travel would likely extend the life of the diesel/petrol car, because i cannot see any sensible replacement for powering jet/prop aircraft. roll on Zeppelins into our future - slow, maybe.
now is the ideal time to invest for the future....

Speaking of air travel ... I've always thought it irresponsible and wasteful for airlines to have such schedules that a plane flies cross country or halfway around the world even when it's less than half full with passengers, just so they can boast they have 20 scheduled flights per day from N.Y. to Paris, or some such rubbish.
More often than not (with few exceptions) no one needs to get anywhere SO quickly that they can't wait another few hours to depart if it means the plane will be full and thus the flight more cost effective. If the number of available flights was reduced, I'm sure we'd all adjust our own plans and schedules, whether for business or pleasure, to make do with that.
Everyone complains about people driviing big trucks and SUVs with only 1 or 2 occupants, getting lower gas mileage, etc., etc., and I'm not saying I disagree. But then why are we not just as appalled with less than half full flights taking off every 10 minutes around the globe, gobbling up expensive jet fuel, spewing putrid exhaust, and often needing to circle an airport many times before landing (thus wasting more fuel) because of a backlog of planes trying to land at the same time caused by a hiccup in the process somewhere along the way.
