The world's going to change climatically. We just want to control the change. We want to have a high quality of life for billions of people as we pass through this era.

Incidentally, the creationists that I've encountered diligently deny that our Earth's climate is being altered by people. This point of view and teaching is in absolutely no one's best interest. Here's hoping we can work together and preserve the Earth, for us - us humans.

Recommending or insisting on abstinence has been completely ineffective.
