Very ambitious idea. I hope you succeed. Where will the first island be near to?
This is very nice project and idea is great.Climate change does change the way we live and it will change even more in future so this could indeed be the best way to go.I think it is a bit early to ask where first island will be as this project needs to sort most important part first and that is funding which I hope will run smoothly so we can see this come to life.
