5. Is that responsible?
But wait. Isnt wild weather happening everywhere? And isnt jet travel responsible for significant global warming? Arent sky-high aircraft emissions destroying the ozone layer? What about the effects of radiation exposure and lack of oxygen on humans as captive as astronauts on long haul flights? Is zooming through thin air more than two miles above the Earth worth the risk to planet and passengers? Or should we be booking with passenger-accommodating freighters, taking the train, or staying home instead?

This is a planetary emergency, after all. The once massive Arctic icecap is nearly gone, and the Awakened Giant of Antarcticas western ice sheet is melting much faster than feared, threatening to drown every coastline like a permanent worldwide tsunami. Nine of every 10 people on the planet lives near current sea levels.

The rising oceans are also turning to acid from all the CO2 pouring into them from our cars, planes and industrial processes. And we are heading quickly toward a cataclysmic release of more than a billon tons of methane from thawing tundra and ocean seafloors. Carbon dioxide is already doing us in. And methane traps 20-times more atmospheric heat than CO2.


Instead, scientists say that more than five million airline flights a year are continuing to significantly affect the rare and fragile atmosphere through which they spew their exhausts. Equivalent in thickness to a sheet of paper draped over a beach ball, this life-giving zone of oxygen and radiation shielding is already being hammered by outmoded carbon-burning engines, woodstoves, cooking fires, and smokestack industries all ceaselessly belching toxic gasses at ground level. Though airlines carry only a fraction of the worlds population, Swiss atmospheric scientist Robert Egli calculates that jet-induced cloud cover and heat-trapping gases account for more than 10% of global greenhouse warming.

Blowing holes in the ozone is stealing from the future and a punishment passed on to the children.
