Answer:
The correct answer is B) There are probably less green parrots today than there once were.
Step-by-step explanation:
The graph shows that most of the green parrots live in the deep forest region. The cutting of the deep forest would destroy their habitat and due to the lack of habitat the green parrots would eventually decrease.
As the question says, half of the deep forest is cut, so, the number of green parrots must be declined in that area.
