Imagine, a September 11 with weapons of mass destruction. It's not 3,000. It's tens of thousands of innocent men, women and children.

The politicians in this world... have at their command weapons of mass destruction far more complex than their own thinking processes.

Certainly it is wrong to be cruel to animals and the destruction of a whole species can be a great evil. The capacity for feelings of pleasure and pain and for the form of life of which animals are capable clearly impose duties of compassion and humanity in their case.
