Myth 113 Land reclamation causes sea level to rise I read this from Sammyboy. And I find this the most logical reason so far for the flooding in Malaysia and Indonesia. You see, we have been reclaiming land from the sea for many years. And land reclamation from the sea means we have to fill them up with sand. And after so many years of filling the sea with sand, of course the sea level will rise. And naturally this will lead to flooding. If you don't believe me, fill a bath tub to half full. Then pour sand into it. Bravo, the water rises in the bath tub. Theory proven. It is so scientific.
