A friend of yours loves hamsters. He has brown, red, and white hamsters. Some have blue eyes and others have brown eyes. A pet store will pay $15
dollars for each red hair hamster with blue eyes, but only $2 dollars for the
other varieties. Explain to your friend how he can make the most money
selling hamsters. Be specific about what he will need to do.

breed the red hamsters with blue eyes in hopes of getting their babies and sell them I have no idea what else you could do lol.

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
