Rob Dunn: In essence we have this story of the history of the Earth as told through life that's all around us - this great library of life - and we're burning books more rapidly than we ever have before, without looking first to see what the books are.

He's speaking about the possibility that hundreds of thousands of tiny and unknown species are now vanishing from Earth, at an unprecedented rate. Coextinction is the extinction of one species when a species it depends on goes extinct. Dunn said many parasites are at risk, because they depend on what are called host species for their food, or shelter. He said scientists don't know exactly how many parasites will go extinct in the coming years, or how many parasites will find new hosts. The greatest value in thinking about the conservation of these parasites, or just better understanding these processes, is that ignoring them could have incredible consequences for our public health, for our crops, for our economies. Dunn added that the disappearance of these tiny but important creatures would constitute a major loss of biodiversity on Earth.
