How do you explain farming can cause deforestation?

Trees, and plants in general, affect the water cycle significantly:

  • their canopies intercept a proportion of precipitation, which is then evaporated back to the atmosphere ( canopy interception );
  • their litter, stems and trunks slow down surface runoff;
  • their roots create macropores – large conduits – in the soil that increase infiltration of water;
