He shares the example of the use of DDT and the effect it has on penguins. Stopping the use of DDT in agriculture is not because of the ill effects it was having penguins, but because of the enjoyment that people got from seeing the penguins. By continuing the use of DDT people would not be able to see the penguins once they became extinct resulting in less satisfaction throughout life.( Baxter, 1974) Another example that Baxter gives is that of the use of washing machines and hospitals. Humans get much satisfaction with the ability to just throw clothes into a washing machine than washing them by hand, but washing machines create pollution. In order to reach zero pollution one would have to give up the use of a washing machine, which would lower the overall satisfaction of life. This is because of the pollution created by the washing machine (the cost) does not out weight the human satisfaction of using the washing machine (the benefit). (Baxter,
