New techniques mean that wood can now be used for much taller buildings - "Wood has many attractions as a construction material, apart from its aesthetic qualities. A wooden building is about a quarter of the weight of an equivalent reinforced-concrete structure, which means foundations can be smaller. Timber is a sustainable material and a natural 'sink' for CO2... Using wood could reduce their carbon footprint by 60-75%, according to some studies. There are two main concerns about using wood to build high. The first is whether wood is strong enough... the second worry: fire."
The total number of trees is close to about 3.04 trillion - "Crowther's group looked back in time and calculated that the Earth has actually lost nearly half its trees since the start of human civilization. 'We're losing 10 billion trees every year and that's a net number'. So how did the group with the lofty goal of planting a billion trees react to these numbers? Their new goal is to plant a trillion trees." (oh and be sure to Meet Hyperion, the World's Tallest Tree! ;)

Obviously, the answer to global warming is to cut down all the trees. Or maybe we should just paint them all white?
