From the soles of shoes to contact lenses, from the smartphones we carry around in our pockets to the toothpaste we use every day to clean our teeth, there is no doubt: we live in the plastic era. Everywhere around us, plastic is the most widely-used and long-lasting product, but also one of the most dangerous. From the 1930s up to the first decade of the 21st century, world production of plastic increased from 1.5 million tons to over 280 million tons (with an increase of 38% in the past 10 years). The outcome is obvious: the more plastic is used, the more of it is thrown away, directly or indirectly, into the environment and in particular into the seas and oceans all over the Earth.
