Which African country is losing its rainforest the fastest?

What is deforestation and its causes and effects?
The loss of trees and underbrush allows for flooding, soil erosion, higher temperatures, and desertification to occur more rapidly and exponentially. While it may seem that natural occurrences are to blame for the majority of tree loss, it is — in fact — human activity that causes the most deforestation worldwide.
What is deforestation explain its causes and effects?
Deforestation refers to the decrease in forest areas across the world that are lost for other uses such as agricultural croplands, urbanization, or mining activities.

How will deforestation affect humans?
But deforestation is having another worrisome effect: an increase in the spread of life-threatening diseases such as malaria and dengue fever. For a host of ecological reasons, the loss of forest can act as an incubator for insect-borne and other infectious diseases that afflict humans.
What are the causes and consequences of deforestation Class 8?
When the forest trees are cut down,the percolation of rain water into soil is reduced. A lot of rain water from deforested soil rushes into the rivers quickly,causing floods. Deforestation decreases the water holding capacity of soil which leads to floods. The eroded soil is carried by flowing rain water into rivers.
