Christians aver that a butterfly never seen by human eyes nevertheless has the end to glorify its Maker, providing God with a small dosis of enjoyment as She watches its beautiful wings flutter. (pg 16, Nov 2008)
The statement is simple, but it is probably the most convincing argument I have heard against the standard approach for assigning value to environmental goods. Even if people are not willing to pay money either to visit the butterfly or to simply know that it exists, that does not mean that the butterfly is without value.
Now I have to reconsider my thinking on the environment.
