There is a natural way of expanding islands as well. Subsidence often cuts off landmasses that become islands, and suboceanic mountains may, due to continental shiftings, suddenly emerge and will often be enlarged by the deposition of coral. Finally, there is quite a few islands of volcainc origin.
EFM works with several ways of provoking one or more of these processes to take place near Madagascar. We are assisted by two geologists from the University of Miami in our plans to implement the "natural" causes.
