WHAT DO YOU GUYS THINK?

That would be quite a site to see and if it helps the sustainability of the earth I am all for it.

i read somewhere that the desert expands 6 inches a year, this seems like a good idea considering nothing else besides the bacteria and some scientists are needed. but how much bacteria would it take? seems like alot…

yeah! one of the reasons behind the wall was to stop the desert from expanding and I think the bacteria they would use is readily found.

Magnun Larsson, an architecture student from London has proposed an idea to transform the Sahara Desert by creating a 6,000 km wall of sandstone. His proposal was awarded the top prize at the Holcim Foundation’s Awards for Sustainable Construction. The purpose wall would not only create an oasis by providing to create an oasis by providing shelter, water, and vegetation within the harsh Sahara Desert, but it would also stop the Sahara Desert from expanding.

Amazingly, the limestone needed for the 6,000 km wall would be created entirely by utilizing bacillus pasteurii, which is a bacteria that when combined with regular sand turns into hard limestone.
