Human activities that aggravate soil erosion

1. deforestation 2. illegal logging 3. overgrazing 4. quarrying

EFFECTS ON PLANTS

1. - since topsoil is easily carried away by wind, the organic materials that serve as nutrients to the plants are also carried away thus plants will not grow faster. 2.-Sediments washed away by water clogged irrigation system thus cause less supply water to crops 3. - too much erosion cause soil to lose its ability to hold and absorb water, soil become dry and coarse thus causing the soil not suitable for vegetation anymore
