9 February

It's always been called a crazy idea, but these are times of possible emergency. It is interesting to wonder how Australia could be changed by trying to create an inland sea again. Pumping sea water to the interior. Would be hugely expensive and maybe impossible from the engineering point of view. But getting a large body of water back in that red centre could potentially change the climate of the entire country (in a good way, for life). It's that big red centre which bakes in the sun and makes the rest of the country increasingly hostile to life. The Africans are trying to hold back the Sahara with a huge green belt of vegetation, maybe planetary-scale projects have found their time.
