SNIP: Since we started engineering polymers to make plastic on a mass scale in the 1950s, this byproduct of the petrochemical industry, which uses about 6% of all the oil we extract a year, has spread to myriad manufacturing processes. Plastic is now ubiquitous, insidious and impossible to avoid. It makes up our clothes, containers, bottles, electronics, food trays, cups and paints. Our cars depend on it, so do our computers, roofs and drain pipes. It’s the global packaging material of choice. We sleep on it, wear it, watch it, and are in direct bodily contact with it in one form or other all day and night.

It may have profound societal benefits, but this most successful of all manmade materials sticks around for centuries. When exposed to sunlight, oxygen or the action of waves, it doesn’t biodegrade but simply fragments into smaller and smaller bits, until microscopic or nano-sized particles enter the food chain, the air, the soil and the water we drink.

In the past few years, minute microplastics and fibres, measuring the width of a human hair or far less, have been found in an extraordinary range of products, such as honey and sugar, shellfish, bottled and tap water, beer, processed foods, table salt and soft drinks.

The more researchers look, the more they find in the human body. The same scientists who raised the alarm on air pollution from the deadly particles emitted by diesel vehicles are now finding plastic microparticles raining down on cities, and blown into the air from cars and construction sites, washing lines and food packaging. Indoor plastic pollution may be even worse than outdoors.
