Terrestrial, aquatic and marine ecosystems are more linked than we realise, and plastic pollution in one ecosystem can have cascading effects elsewhere. Plankton – key indicators of healthy aquatic ecosystems, are being adversely affected by microplastics, and the planet’s carbon sinks are in serious danger. The largest division on the geological time scale (GTS), which depicts distinct time periods in geological history, is called eons. Eons are further divided into eras, which are divided further into periods, epochs, and ages. The Anthropocene – a proposed, but still to be accepted term, represents the epoch when human activity began to leave an indelible, irrefutable mark on the planet. Plastic is poised to be the most perceivable, persistent and pervasive indicator of the Anthropocene era. How has plastic become a...
