I encourage you to expand your awareness regarding the air pollution caused by aviation and rocketry.

The amount of air pollution that is caused by global aviation and rocketry is absolutely incomprehensible.
Many people are concerned about visible persistent contrails, but only approximately 5 percent of all mileage flown by global jet aircraft results in the formation of visible persistent contrails.
Approximately 95% of all chemical trails are INVISIBLE!

Only a small subset of flights occur in ice-supersaturated (humid) regions of the atmosphere, causing the contrails to persist for hours or even days, gradually turning into cirrus clouds. Wintertime conditions often see 1.5 times more persistent contrail coverage than summer.
