Airplanes burn an enormous amount of fuel, which releases carbon dioxide and other undesirable gases into the atmosphere, so airplanes are environmentally harmful. Dirigibles would be a more environmentally benign form of air travel.

Burning fuel causes CO2 to pollute the earth causing global warming. Our children are going to pay for it. Greener planes mean a greener life!
Planes emit a lot of carbon dioxide, the most significant greenhouse gas, into the atmosphere. Aircraft emissions are about 3% of all CO2 emissions in the world.
