Original Note:
Those are contrails. Contrails are made up of ice formed from the combination of water vapor in aircraft engine exhaust and cold temperatures that exist at high altitudes causing condensation allows the formation of the trails. They have no effect on humans. https://www.faa.gov/about/office_org/headquarters_offices/apl/noise_emissions/contrails/
