Global warming
A bike dealer who mentions global warming may indeed be guilty of the same self serving cheap promotion as the car dealership, which flies an over sized American flag or the politician who presumes to speak for ‘all hardworking folks’.
Be this as it may, the earth is “on the verge of disastrous climate changes that spiral dynamically out of humanity’s control, causing mass extinction, ecosystem collapse and dramatic sea level rises.”
James Hansen, the chief climate scientist at NASA, returned to Capitol Hill in June, on the twentieth anniversary of his 1988 testimony, to indeed warn that the earth is on the verge of “disastrous climate changes that spiral dynamically out of humanity’s control,” causing “mass extinction, ecosystem collapse and dramatic sea level rises.”
Obviously no amount of bicycling shall reverse or by itself significantly slow the spiraling.
Nothing shall. Short of perhaps radical life style changes right now, which clearly ain’t happening.
But for all its horror I’d personally rather know than living in denial of my own betrayal of future generations. Being only one of some 7 billions humans cannot lessen my complicity. I have sadly done nothing beyond mildly inconveniencing myself regarding arguably the greatest calamity that can possibly face life on planet Earth.
