At the Movies

(Fox News) - Another case of environmentalists fighting among themselves. It concerns the new global warming movie — "The 11th Hour" — produced and co-written by actor and activist Leonardo DiCaprio.

The film contends that cutting fewer trees and using less wood would be beneficial to the environment. But Greenpeace co-founder Patrick Moore writes on Canada.com the opposite is true — that using more wood, and growing more trees — is a better plan. Moore says trees absorb carbon dioxide — convert it to wood — and that wood retains the CO2 when it is cut down. He says trees release the carbon dioxide only when they rot or burn.

Moore says increased use of wood could lead to less use of concrete, steel, and plastic — which produce large amounts of CO2 during manufacturing.
