Today, human-made stuff equal to each person's body weight is produced every single week for everyone alive globally. This 'anthropogenic mass', which at the beginning of the twentieth century accounted for only about 3 per cent of all biomass (all the trees, shrubs, other plants, animal bodies, and so on) on Earth, surpassed the overall biomass around the year 2020. The mass of produced plastics alone is double the mass of all the terrestrial and marine animals, including the bodies of humans.
