a, i am pretty sure.
increase soil erosion reduce soil erosion
cattle grazing hydroseeding
deforestation contour plowing
plant roots basically hold the top soil
together and stop soil erosion because
in such situation top soil is not removed
during flood but cattle grazing causes
soil erosion because cattle consume the
grasses and herbs and top soil is exposed.
same situation occurs because of
deforestation, the trees and plants are cut
down to expose top soil which causes soil
they kick it to the curb.
that current was nasty.
