Genetic Engeneering

For example you can introduce a virus(vector) that contains the genetic information necessary for the synthesis of the given enzyme that would normally be poorly synthesized in the sick patient. The vector will introduce the genetic material inside the cell of the  intesinal lining and the intestinal cell will secrete the substance.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

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

erosion
