There are two parts to the answer here. Part of it is, again, like smart phones—who would have guessed how we all use them today? Five or six years ago, a few people were using them, but not very many people. It represents a new way of looking at things; technology does that.
As the science emerges—again, with all of the great work Dr. Chopin does—we're seeing that with IMTA the metabolites that come from a fish farm actually grow seaweed, and they can grow mussels. They're starting to look at other things. What it's really demonstrating is that the ecology you're in has a certain assimilative capacity.
