Land's End

The end of civilization as we know it may occur when we have no land to live on. barring going back into the sea (assuming it's still there), or into the sky, we wouldn't have any options.

Therefore, my theory ( I still can propound a few) is that we, citizens of the world, must value what we have. All land records of the world must be made public, on Google or its equivalent, and we must all decide on what we should be doing with it. Housing of course is a primal need, and we could allocate large portions of land to this. Agriculture may be equally important, and that should take precedence over pointless uses.

After which, other land uses should be decided on by local communities. New communities can also be planned by citizen groups. What's new about this, you may ask. Two things. Transparency- the google part, and citizenry getting involved. Might actually solve a lot of the world's problems, methinks. Royalty cheques, anyone?
