I can see the concern of those who think this is going against the environment by cutting trees. I believe most lumber companies do replant where they cut, hence the 'renewable' part mentioned. I don't like the idea of deforestation either, however, fossil fuels are used to make building materials such as steel, which is also harmful for the environment. I agree that there needs to be more of an effort in reusing wood whenever possible, which isn't mentioned here. I hate to say it, but given the alternative, cutting and replanting trees seems the lesser of 2 evils.
