A
Some species will be extincted

B
Population and ecological imbalance will rise up

C
Energy crisis will occur

D
Rest half forests will maintain this imbalance
Solution
Forest is the home of many of distinct species and even undiscovered species if the forest is uncovered many of the species lost their natural habitat and become extinct which further leads to the following problem like:
Rise in population and ecological balance- The number of producer decreases, the dependent consumers will die out of starvation. This lead to rise in ecological imbalance.
Energy crises- Due to the decrease in the number of producers.
Imbalance in the forest- As the number of producer decreases, the food chain gets disturbed.
So the correct option is 'Some species will be extinct'.
