Chemtrails are the trails that are left behind by some airplanes. They're usually
silver iodide (
AgI), potassium iodide (KI), or Dry Ice ( CO2 (s) , Solid Carbon Dioxide). They are part of a cloud seeding program to make it rain or snow more to help prevent droughts, and to try to cool earth a little more by creating more clouds. It's good for water, but insufficient for global warming, and greener energy options to reduce CO2 emissions (like solar, wind, and maybe
nuclear energy) are needed and not dumping your trash in the ocean so that turtles can eat the jellyfish and not sting you during the summer. There are more wildfires now. Will the earth cool down in time?
