Just think of how many trillions of trees have been saved thanks to the inventiveness of technological geniuses.

Who cares? The act of cutting trees and replacing them removes CO2 from the atmosphere as long as the resulting products aren't burned. I don't know that the net cycle tree-to-wood-to-paper-to-landfill is a CO2 source or sink (since some human and industrial work is required in the above) but it certainly isn't the environmental evil some would claim.

The act of cutting trees and replacing them removes CO2 from the atmosphere{..}

You do know that trees give off O₂ (molecular oxygen), and they remove CO₂ from the atmosphere, right?

How exactly does the act of cutting down trees give off CO₂? I'll give you the only answer to that question. It doesn't, but instead RAISES the CO₂ levels and lowers the amount of O₂.

That's why they should be conserved, where we at least replenish the supply with seedlings when we use what we need.
