We can also cut them to make room for new trees. If we don't burn the C in them to CO2, but use them as raw materials (buildings, alternative to plastics, etc.) there is even more potential for carbon capture in this way.
Of course, the long term solution is to grow as many new trees per year as we emit CO2, so there is an upper limit for our CO2 budget, but this should give use time to convert to carbon neutral energy production and consumption without hampering the the GDP growth too much. In fact, it has been estimated that world GDP can actually grow even during the transition, due to, for example, positive effects of improved environment (health improvements lead to productivity improvements and so on).
