Conservation biologists breed some endangered species like the panda bear in captivity. Which is the most likely reason that panda populations in the wild are still threatened?

Due to unfavourable environmental conditions.

Explanation:

The panda populations in the wild are still threatened because of unfavourable environmental conditions to the survival of panda. The panda become endangered species due to unfavourable and bad environment of the surrounding which occurs because of the human activities. Destruction of habitat is the main reason which is responsible for the decrease occur in the population of panda so we can say that the surrounding unfavourable environment still threatened the panda in the wild.

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
