The Nobel Prize-winning atmospheric chemist, Paul J. Crutzen is considered to have coined the term ‘Anthropocene’, using it in reference to the indelible mark that human activity has now left on our planet’s natural systems and geological record. From our position in recent history this label seems appropriate. If we were to step back and try define the very age of life on this planet however, or even that of ‘biology’ itself, it is arguable that this ‘aeon of life’ would be defined by plants and photosynthesis. Plant activity has influenced every facet of our planet over billions of years and this dominance will continue, even when the Anthropocene epoch eventually fades. Plants are the natural world order and they always will be.
