So Magnus Larsson gave this TED talk entitled “Turning Dunes into Architecture”.  His idea is to build a giant wall across Africa, to halt or at least slow down the desertification process that is happening there.  The idea is to use bacteria that bond with the sand to make it hard, something like adobe.

It’s such a very cool idea, both useful and beautiful, and I wish I had some skills or knowledge that would be useful to such a project.  But unfortunately I have a feeling that, as the saying goes, “technology is easy, politics is hard” and that the things that would stop such a project are political and social.
