This article, written by Adam Frank, a professor of astrophysics, and asks "What does it mean to save the Earth?" Earth, as the blue-planet, the planet with oxygen and temperate climates and sources of life-sustaining resources, has been shaped by life itself. It's Life in the form of blue-green bacteria that has made Earth what it is - and it wasn't always so hospitable.
The Earth's biosphere - the cosmic force that makes life possible - can survive anything that's thrown at it. As he says, the biosphere - which makes life possible - has survived cataclysms far worse than mankind's pollutions for millions of years and bounced back. It is endlessly adaptable. But here's the catch: mankind is not able to adapt the way other more basic life forms can. If we damage the biosphere, it can move on without us - and so the professor makes a case that if we are to save civilisation we need to change our ways.
"Our planet does not need our saving. The biosphere has endured cataclysms far worse than us — and after millions of years thrived again. Even the Earth’s five fearsome mass extinctions became opportunities for the biosphere’s creativity, driving new rounds of evolutionary experiments. That, after all, is how we big-brained mammals ended up dominating the Earth rather than our dinosaur predecessors."
"Mankind needs to make the difference now. "It means we must become the agent for something the Earth has not seen before — a biosphere that is also awake to itself and can act for its future with both compassion and wisdom."
In the long term, the Earth will carry on without mankind....and the biosphere will always bounce back
