No Sand Is Important If You Like Using Concrete

And we all know how ubiquitous concrete is for construction. And if we were suddenly faced with the need to build... I don't know, say, a whole lot of floating cities to make up for all of the coast lines that are going to be under water in the the next ten to twenty years, what are we to do then?

Fortunately my approach to building new structures at sea would use a hemp based composite material. So much of it, in fact, that it could easily become a new, viable export crop for a lot of nations that would find it hard to grow much of anything else. So it would be a win win for us and a significant portion of the rest of the world.

Just some more stuff to think about as we roll ever onward towards a world in permanent crisis mode.
