Life possible on 'large parts' of Mars: study

Australian scientists who modelled conditions on Mars to examine how much of the red planet was habitable said on Monday that "large regions" could sustain terrestrial life.

Charley Lineweaver's team, from the Australian National University, compared models of temperature and pressure conditions on Earth with those on Mars to estimate how much of the distant planet was liveable for Earth-like organisms.

While just one per cent of Earth's volume - from core to upper atmosphere - was occupied by life, Linewaver said their world-first modelling showed three per cent of Mars was habitable, though most of it was underground.

"What we tried to do, simply, was take almost all of the information we could and put it together and say 'is the big picture consistent with there being life on Mars?'," the astrobiologist told AFP. "And the simple answer is yes... There are large regions of Mars that are compatible with terrestrial life." ... http://gulfnews.com/news/world/australia/life-possible-on-large-parts-of-mars-study-1.949189

2. Would be good to get the permaculture specialists onto this

... When there’s no soil, no water, no shade, and where the sun beats down on you to the tune of over 50°C (122°F), the word ‘poverty’ begins to take on a whole new meaning. It is distinct and surreal. It’s a land of dust, flies, intense heat and almost complete dependency on supply lines outside of ones control. This is the remains of what was once called the ‘fertile crescent’. It is the result of thousands of years of abuse. It is a glimpse at a world where the environment – whose services provide for all human need – has all but completely abandoned us. This is a glimpse at the world our consumer society is inexorably moving towards, as our exponential-growth culture gorges itself at ever-increasing rates.

The original Greening the Desert video clip has been watched hundreds of thousands of times and has been posted to countless blogs and web pages in the datasphere. Although only five minutes long, it has inspired people around the globe, daring the lucid ones amongst us, those who can see the writing on the wall, to begin to hope and believe in an abundant future – a future where our survival doesn’t have to be based on undermining and depleting the very resources of soil, water, phosphorus, etc. that we depend on. The work profiled in that clip demonstrates that humanity can be a positive element within the biosphere. Man doesn’t have to destroy. Man can repair...
