Question

Which of the following is not an environmental challenge facing the African continent?

Answer 1

The African continent isn't suffering from the environmental challenge "reforestation", since most of the continent hasn't suffered deforestation. 

Answer 2

Deforestation can be one of your answer. The area around there is not built up, and so there isn't a lot of companies that will go their to get wood (it is more expensive)

hope this helps
