He cuts down trees to protect the climate: forester pursues a paradoxical plan. Trees save the climate - if you cut them down, explains Robert Nörr.

The wood of the trees stores carbon dioxide (CO2) Simple formula: the more trees, the fewer pollutants in the atmosphere. After felling, construction wood and pellets can be used to replace CO2-intensive raw materials such as concrete and oil or gas. And the offspring of trees uses the free space: young plants only grow when they get light - and in the process bind carbon.
