We cheat nature in many ways. What are you talking about? We have antibiotics to stop many illnesses that occur naturally in our environment. We cheat by making hybrid foods. We cheat by altering the coarse of a river with dams and levees.

For example, pregnant women are taking drugs so that their babies can be born with green eyes, blonde hair etc. But who is to say that this won't cause any damage to the child's health?
