Microplastics reach the top of the food chain. Tiny plastic particles (from 50 μm to 5 mm in diameter) have been found in human poop. That means we're eating or ingesting them from the air (as in the breakdown of synthetic fabrics, breakdown of larger debris like bottles, and from plastic beads in some cosmetics). The sample size was 8, all living in Europe or Asia. All of them produced contaminated poop. Obviously much more work is called for, such as figuring out how much of the plastic remains in the body, where it goes, if it's toxic, and if even smaller plastic particles are "able to penetrate the gut lining and enter the circulatory system and other organs, such as has been found to happen with other nanosize, man-made particles." Lovely. I'd like to think this might deter people from being irresponsible in disposing of plastics, but we all know that won't happen until we're shitting out gallon juice jugs into the toilet.
DeSmogBlog has an article listing many of the climate deniers running for office this November. Probably not all. Obviously all Republicans, except for one North Carolina Democrat who avoided the question in a debate. The question I wish the media would start asking is, "what is the cost of not addressing climate change?" Stop asking if they believe in it or not. That's like asking if they believe in gravity and hearing someone say "no." AGW is a given.
In Zen and the Art of Motorcycle Maintenance, the author, in a discussion with someone, argues that gravity didn't exist until Isaac Newton. I took it he meant the concept of gravity, not the actual curvature of spacetime. That's a book I should put on my list to read again soon.
A 2003 paper by the physicist Brian Josephson (Nobel Laureate for work he did when he was 22 years old) has the title, "We Think That We Think Clearly, But That's Only Because We Don't Think Clearly."
