Why do spray chemicals in the air and what are the side-effects?

Question everything!! | What are Chemtrails and what differs them from Contrails?

Lab results from ground samples taken from 2 unassociated parties (Sacramento and E.Oregon) after flyovers from unmarked aircraft reveal biowarfare bacterias named in over 160 Pentagon patents referencing biowarfare applications, toxic molds, ethylene dibromide (a pesticide banned by the EPA which damages lungs/heart/liver/kidneys).

I. Contrail vs. Chemtrail.

A. A contrail dispurses. A chemtrail spreads into cloud cover and sometimes has fallout (cob-web like filaments, red/yellow powders, milky-white fluid).

II. Purposes (??? weather modification, protection from ozone holes, bio-vaccination, culling – ???)

A. Weather modification.

Most people discover the reality of chemtrails by initially reading about it on the Internet and then going outside and looking up into the sky. They are shocked to realize that what they had been reading about (and studying photographs of) is also taking place right over their heads. What some people had dismissed as mere “jet plane exhaust” (because there are now scores of internet propaganda web sites trying to convince you that ‘everything is well’ and ‘there’s nothing to be alarmed about’ and that unaccountable ‘jet plane exhaust’  plumes are magically being converted into horizon-to-horizon overcasts of “cirrus clouds” !) are dismayed to realize that chemtrails are indeed the toxin-laden aerosols that have been described here and at other web sites since 1998 and they are not being sprayed for any benign or national security reason as the disinformation peddlers would have you believe.

When a jet engine is spewing out hot, humid air into an atmosphere that is cold and has low vapor pressure, the result is condensation. The water vapor coming out of the engine quickly condenses into water droplets and then crystallizes into ice. The ice crystals are the clouds that form behind the engine. This is why the streaks are called contrails, short for “condensation trails.” To help explain it, scientists liken it to seeing your breath on cold days. You may have noticed that puffs of breath dissipate quickly on dryer days. The same is true of contrails: When the atmosphere is more humid, the contrails linger, but when the atmosphere is dry, the contrails disappear more quickly.
