Humanity’s impact on the Earth is so profound that we’re creating a new geological time period. Geologists have named the age we’re making the Anthropocene. The changes we’re making to the atmosphere, oceans, landscape and living things will leap out of the rocks forming today to Earth scientists of the far future, as clearly as the giant meteorite that ended the Age of the Dinosaurs does to today’s researchers. In this four part series, journalist Gaia Vince looks at the impact of these planetary transformations from the perspective of geological time. When was the last time comparable events happened in Earth history, and are what are the key marks we’re making on the planet that define the Anthropocene?
In this first programme, Gaia hears how the hand of humanity on the surface of the continent is geological in its sheer scale and its imprint will remain for millions of years. Through mining and quarrying, we shift billions more tonnes rock and sediment annually than all of
