Deforestation in the Amazon

I thank my right hon. Friend for giving way and for securing this debate. My argument with the Brazilians is twofold: not only is there deforestation, but, as my right hon. Friend was just saying, they are not actually making good use of the land when they farm it. Basically, they farm all of the fertility out of the land, then leave it and move on to other land. It is bad in all respects, not only for the environment, but for agriculture.
