The second reason to abandon environmental religion is more pressing. Religions think they know it all, but the unhappy truth of the environment is that we are dealing with incredibly complex, evolving systems, and we usually are not certain how best to proceed. Those who are certain are demonstrating their personality type, or their belief system, not the state of their knowledge.

The past history of human belief is a cautionary tale. We have killed thousands of our fellow human beings because we believed they had signed a contract with the devil, and had become witches. We still kill more than a thousand people each year for witchcraft. In my view, there is only one hope for humankind to emerge from what Carl Sagan called "the demon-haunted world" of our past. That hope is science.

For our own species, evolution occurs mostly through our behavior. We innovate new behavior to adapt.

The purpose of life is to stay alive. Watch any animal in nature--all it tries to do is stay alive. It doesn't care about beliefs or philosophy. Whenever any animal's behavior puts it out of touch with the realities of its existence, it becomes exinct.

It's not easy to cut through a human head with a hacksaw.

God created dinosaurs. God destroyed dinosaurs. God created Man. Man destroyed God. Man created dinosaurs. Dinosaurs eat man...Woman inherits the earth.
