What type of evidence could be used to convince policy makers to pass a law to reduce overfishing, and how does this show cooperation between scientists?

a.) scientists could collect and combine data on fish populations all around the world to show that their populations are declining.
b.) scientists collect and combine data on fish populations all around the world to show that their populations are increasing.
c.) scientists work together and use past data to show that fish populations are becoming locally extinct in some areas.
d.)scientists work together and use past data to show that some fish populations are adapting to environmental changes.

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

the glands which are associated with each description is given below:
