Well, let's see...increased oxygen production, absorbtion of the CO<sub>2</sub> gasses, an increase in natural habitats for many animal species...there are all sorts of advantages to having more trees. What would make you think it's a bad thing?
Oh, well, we're in luck then:

Grasses are highly evolved to use carbon dioxide efficiently. Ecological balances between grasses and other plants will be destroyed if the grasses' advantage is diminished.

A team of Swiss and Portuguese scientists grew ryegrass in open fields near Zurich where atmospheric CO2 levels were maintained at 350 ppm and 600 ppm. Here’s a twist: the scientists stayed with their experiment for six years. Daepp et al. found that after the first year the grass increased its dry weight by seven percent. By the sixth year, dry weight had risen to 25 percent thanks to higher CO2 concentrations. Their result suggests that all those one and two year studies we’ve cited as evidence of a benefit from higher atmospheric concentrations of CO2 may in fact grossly underestimate it.
Another Swiss team (including some researchers from the experiment just described) grew various grasses in 1994 and 1995 in an open field where they maintained atmospheric CO2 concentrations at ambient and near-twice ambient levels. When the grass grew under conditions where there were low levels of nitrogen, the grassland increased its overall biomass by 13 percent. Under high nitrogen conditions, the grasses revealed a 30 percent increase in response to higher CO2. When last we checked, nitrogen was not in short supply, so our pastoral future looks mighty green.
Van Ginkel grew this same ryegrass specie for 115 days in growth chambers with atmospheric CO2 concentrations of 350 and 700 ppm, after which some chambers had their temperature increased by 2°C for 230 days. The researchers observed that elevated CO2 substantially increased root biomass and wrote, "Root biomass is the driving parameter for all subsequent below-ground processes in our plant-soil system." (Layman’s translation: Increased root biomass is good news for plants.) Further, beneficial microbial biomass increased by 46 percent under elevated CO2 conditions. Finally, increased temperature appeared to have little negative effect on the benefits resulting from higher CO2. Put another way, ryegrass grown under elevated carbon dioxide concentrations withstands higher temperature better than it does under current concentrations.
How can you be stupid enough to believe that you've made a viable point?
