The correct options are
A Migration of tribal people towards cities
B Migration of wild animals towards cities
D Extinction of several species of plants and animals
Deforestation refers to the excessive cutting of trees. Due to the clearing of trees in the forest, the tribal people are forced to leave their home and move to cities. Many species of plant and animals disappear due to deforestation. Due to loss of habitat, the wild animals also move to human settlements in search of food and shelter.
