Plastic, plastic everywhere
When we discard a plastic bag, an electronic device encased in plastic, a plastic pen emptied of its ink or any of the myriad plastic objects which populate our lives, we usually say we are throwing the object “away.” By that we mean into a trash or recycling bin and from there to a landfill or recycling facility.
I put “away” in quotes because if there were ever any piece of evidence to convince us that there is no “away” in the sense described above, it is the discovery of tiny particles of plastic in the Arctic ice, deep oceans and high mountains.
These so-called microplastics are so ubiquitous now that they are believed to be floating in the air practically everywhere. Some tiny plastic bits have been seen the lungs of cancer patients who have died. Humans not only breathe them in, but also supposedly eat 50,000 of these particles every year.
And, of course, we know absolutely nothing about the potential health effects of these microplastics on humans. We are frequently told that the novel chemicals humans design are supposed to bring us advantages which will make our lives better, more productive and less toilsome. The problem is that once these are released into the environment, they go everywhere.
The industry line is that these releases are small, and that any which end up in the bodies of humans and animals will have little or no effect. But this has proven to be merely an industry ploy designed to delay the recognition of hazards as I wrote a few weeks ago.
There has been for some time a movement called “green chemistry” which aims to reduce the hazards associated with synthetic chemicals significantly. It does not, however, aim to eliminate them, at least in green chemistry’s current form.
