Pivotal Moment

http://www.nasa.gov/multimedia/imagegallery/image_feature_90.html We seem to be discovering, at the same time as we warm up our own planet to dangerous levels, that billions of years of ago Mars was possibly as habitable as the Earth used to be till we started mucking about with it.
It suggests that there is evidence ‘next door’ in the solar system of
the dangers of climate change. This at a time when, as a community, the human race are making momentous decisions about our long term future. And yet some are arguing for us to abandon the Earth and try and set up home on Mars!
Let us hope that as the coming weeks unfold, the people on whose watch this crucial time has fallen have their feet on the ground – for all our sakes.
