We don't even know what species are out there, for the most part, particularly when you get down to the microbes and very small invertebrates. They make up the mass of the organisms around us, including the soil we depend on, the soil of cornfields as well as hardwood forests. We haven't taken ecology to the point where we can even make a crude prediction of what's going to happen when we've reduced the living world down to a certain level.

We don't know the functions of most of them, but they may be more vital for the planet's future sustainability than we can even dream. And we have to find out; we need to be doing this sort of study.
