Leaching
By removing trees, there are less nutrients in the soil, decreasing soil fertility
soil erosion
plant roots hold soil together and slow down the rate of surface run-off. Without roots, the soil is less compact and more likely to be eroded

eutrophication
-
algae flourish, growing rapidly
algae bloom prevents sunlight from reaching aquatic plants, so water oxygen levels fall
the rate of decomposition increases, further reducing the volume of dissolved oxygen , because the decomposers are aerobically respiring
