Written in a popular style, rather than academic or scientific, it makes the following positive argument:
* Future prosperity on a global scale will require large increases in basic food production, especially high quality protein.
* Measured in millions of square miles, the world’s shallow water tropical fisheries are the only natural resources left capable of supporting such large increases.
* The present methods of hunting and catching fish will have to be replaced with cultivation.
* This cultivation will require placing structures on the sea floor.
* The best place in the world to begin this process is on the La Parguera shelf off the south coast of Puerto Rico. Yes, it is the reason I wrote this letter and an easy argument to make. Check it out.
* The La Parguera shoreline and the La Jas valley just inland are best place in America to conduct solar thermal research. It is not just latitude, latitude, latitude; it’s the rain shadow from mountains to the east that gives the whole area a very high number of bright sunny days every year.
* Combining both new technologies would greatly increase the efficiency of both.
* A successful venture on the shelf would spread rapidly.
* The new technologies will require increased production in related industries.
