We've been informed there are 1 million passengers in the sky at any time, This amount of flying uses about 20,000,000lbs of fuel per hour, producing 64,000,000lbs of CO2 and 36,000,000lbs of H2O. Every hour.

Over the years this has been happening I wonder if it has an effect on the global climate. Also 100lbs of fuel burns 400lbs of oxygen O2. All at high altitude.

Politicians and corporate entities don't seem to acknowledge this; too much investment. Easier to blame the people on the ground.
