anthropocene man

Very inspiring and scary stuff - Johan Rockstrom talking at the WWF’s Inaugural living planet lecture as part of the new Living Planet Report, after an introduction by Sir David Attenborough. We are likely entering a new geological epoch called the Anthropocene- the first man made epoch… and it isn’t looking good. The epoch we are in now (Holocene) has lasted 10,000 years. We are about to transition into the Anthropocene epoch in just 50 years time. This is because the planet has become grossly overpopulated from 1990 onwards, and we have started to exhaust Earth’s resources as a result. The natural world has remarkable resilience but it is not enough. To save diminishing wildlife and ecosystems (and ultimately ourselves) we have no choice but to come together in a “Planetary stewardship” and introduce a carbon law. @wwf #LivingPlanetReport

Humanity Is a Geologic Force “as Earth-Changing as a Meteorite Strike”

‘The idea that humans are fundamentally and irreversibly impacting the planet is impossible to ignore. But are we a geological force, on par with volcanoes and plate tectonics? A new study published Wednesday in the journal Nature says yes: “Human activity is now global and is the dominant cause of contemporary environmental change.”’

Recent study identifies two newly theorised starting points of the ‘Anthropocene’ - the geological period in the Earth’s history where human impact and activity has caused permanent global change.

One period suggested is around 1610, with the European arrival in the America’s and epitomising the height of colonisation and global industrial trade.

Another is from 1964 when the world peaked in levels of radioactive fallout from nuclear weapons testing.

What these show is that humans have had a clear and observable effect on how we shape the Earth in the short time we have been on it.
