This was quite philosophical at times. Does it make sense to save a species that is then unable to live in the wild? Is it fair to that animal? What constitues true conservation? Life at all costs? There are even DNA banks, called frozen zoo's, with samples of over a thousand different species of insects, fish and mammals saved in them. (10,000 individual cells.) To what end remains to be seen. Overall it was a facinating read and I learned a lot.
