International co-operation is vital if we want to protect the plants and (particularly) animals that we share the planet with. They don't all have a very quantifiable value, and often those most at risk live in countries in the developing world where it is hard to balance the growing needs of the population with effective conservation measures. It's also, of course, rather rich to be lectured by the developed West/North on how to look after your flora and fauna when we have been so remiss ourselves.
