I was doing some gardening early on Monday. It was a beautiful morning and when I looked up, I was startled to see so many plane trails in the sky. In fact, there wasn’t a cloud in the sky and everything I could see was caused by plane pollution. It was really surprising, and got me thinking about what a problem plane pollution is and why we generally just ignore it. This prompted me to investigate a number of articles on the internet (you can see links to all these articles below along with the most interesting quotes from each).  It’s clear that plane pollution is one of the major problems we’re facing as humankind, and we need to do something radical and quickly.
