A great study that suggest South America is so fertile because the winds of Africa blew over ocean minerals that landed on South America is an example of why scientist believe that all land needs to sink and spend a few million years at the bottom of the ocean.
NORTH AMERICA was at the bottom of an ocean for a very very long time as was all the land on earth visible above the water line........
If I lived near an ocean, I would use the water on the soil.....and bathe in it, etc.
