As fossil-fuel derivatives, plastics are made of refined carbon. By 2015, about 6.3 billion tonnes of plastic waste had been generated, with around 79% of this accumulating in landfills or the natural environment, where it breaks into ever smaller pieces. Each year, plastic production increases exponentially: the total weight of carbon in plastic has surpassed the mass of all animals combined, and is likely to equal the mass of all bacteria by 2095 (see 'Litter legacy').
