Conservation often focuses on the species on the brink of extinction – the Sumatran tiger, the white rhino etc. Once a species is gone, it will never return. However, we depend on a network of ordinary creatures whose numbers are dwindling too. For example, pesticides have resulted in far fewer insects. So, that’s less pollination for the plants we eat, less food for birds and bats. We should care too for these common creatures. We depend upon an abundance of the ordinary.
