Anyone watched this?
http://www.abc.net.au/tv/programs/supersized-earth/
It's about how our human constructions are changing the face of the Earth...
One of the segment talked about
Greenhouses in Almeria, south of Spain, where they have built 26,000 hectares of Greenhouse on desert lands in the last 30 years to grow crops, enough to supply half of Europe!
If only we can do this on our Australian desert! Wouldn't it give a lot more people job and export power? Though, the way these greenhouses run in Almeria seems to be fairly inhuman and environmentally damaging according to that article..
But just how you can see all of them from Google Earth is fascinating!
