How Plane Fuel Kills 8,000 People a Year

From fastcompany.com...

"As if airlines needed any more reason to reduce fleet emissions, MIT reports this week that pollution from airplanes flying at cruise altitude (approximately 35,000 feet) cause 8,000 deaths globally each year.

Current emissions regulations only target planes flying up to 3,000 feet. In the past, regulators assumed that emissions above the 3,000 foot mark would be dumped into a part of the atmosphere with smooth air that couldn't send pollutants drifting toward the ground (the air is more turbulent at lower altitudes). But MIT has found that that's not true--and unfortunately for those of us on the ground, 90% of aircraft fuel is burned at cruise altitudes."
