Professor John FitzGerald:

The Soviet-style national planner might have said a certain amount of land should be used for this, that or the other. Telling farmers what they are to do is not the route to go. Using much more land to suck carbon from the atmosphere is important. We should remember that grassland, if used correctly, can perform some of this role. We need to shift from the land use that currently contributes to the problem to land use that can help solve the problem.
