Those Microplastics Get Everywhere!

'Clean' air samples were filtered, between June and October 2017, at the Pic du Midi Observatory. The observatory is almost 3000m above sea-level in the French Pyrenees. Every single sample in this CNRS study contained microplastics (https://www.theguardian.com/environment/2021/dec/21/no-mountain-high-enough-study-finds-plastic-in-clean-air). Microplastics are even found high in the troposphere, where winds can carry them rapidly around the planet. Is it any wonder that these tiny pollutants are found from the top of Everest to the depths of the Mariana trench? Microplastics endanger the health of humans and other animals. Self-abuse?
