The idea that we can go to Mars is touted by NASA, Elon Musk, and so many others that this dream seems just around the corner. If we destroy our planet with climate change, pollution, biodiversity loss, soil erosion, aquifer depletion and more, no problem! We can go to Mars.
Though not if peak oil arrives, which it may have in October 2018, there won’t be fuel to get there, and certainly none to return to Earth.
But as Ugo Bardi points out in his book Extracted: How the Quest for Mineral Wealth Is Plundering the Planet we already have gone to another planet by exploiting Earth so ruthlessly that we have changed our planet into another world.
“The planet has been plundered to the utmost limit, and what we will be left with are only the ashes of a gigantic fire. We are leaving to our descendants a heavy legacy in terms of radioactive waste, heavy metals dispersed all over the planet, and greenhouse gases—mainly CO2—accumulated in the atmosphere and absorbed in the oceans. It appears that we found a way to travel to another planet without the need for building spaceships. It is not obvious that we’ll like the place, but there is no way back; we’ll have to adapt to the new conditions. It will not be easy, and we can speculate that it will lead to the collapse of the structure we call civilization, or even the extinction of the human species”.
Go to Mars? Really? Been there, done that on Earth, and it didn’t work out: Biosphere 2
Remember the $250 million 3.14 acre sealed Biosphere 2 complex near Tucson, Arizona? It was built to show how colonists could survive on Mars and other space colonization but they only made it for 2 years ON EARTH.
