By the same logic, you could say that oil, coal, and natural gas are not net contributors either.

That's not great logic, because the carbon in plant biomass was recently removed from the atmosphere (you could stretch this back a few hundred years for the longest lived plants), while fossil fuels go back millions of years, and that carbon was effectively removed from the Earth system until human activities "reactivated" it.

Does that, then mean that current schemes to sequester it on site is just creating an even bigger problem down the road?
