Desertification has become a major issue in Africa,
specifically in sub-Saharan Africa. The area most at risk is the Sahel, the area that borders the
southern edge of the Sahara. This region serves as a “transition” between the
desert and savanna the
grasslands that dominate much of sub-Saharan Africa. The centrally-located tropical rainforest region is
not immediately affected by the threat of desertification.
The term
“desertification” refers to the growing size of deserts, but in this case the Sahara. There are many causes of
desertification: some are naturally occurring while others are caused by
humans. The most common natural cause is drought,
which is something you might associate with the desert itself. However, this
situation can cause great harm to soil, making it unusable and causing<span> erosion</span> by wind or human
activity.
As far as human activity goes, there are number of them that cause
desertification. Cattle ranching- a common occupation in much of rural Africa-
can cause overgrazing.
Additionally, the need for more and more food to feed people in and outside of
Africa results in over-farming.
In both cases, these practices cause soil to become more exposed to the sun and the increasingly dry weather. As the
soil loses nutrients and is loosened by other forces, it ceases to be able to
grow any plant life, creating a situation in which the desert may slowly begin
to creep into an area.
The effects of desertification can be catastrophic. Starvation is the most common
effect, and one that is not quickly or easily solved. Soil that is unusable can
take many generations to replenish.
Similarly, ending or slowing down desertification is cannot be done with a
single effort. Military
campaigns are being undertaken in Africa, encouraging the use of beneficial
practices such as crop rotation
and smarter ranching
practices in order to prevent further soil depletion.

Answer: B
Explanation: The correct option is letter B, cognitive-behavioral therapy plus and antidepressant. When treating anxiety disorders you discover in almost every case that is an emotional disorder underneath, because anguish is the other side of anxiety.
If you treat an anxiety disorders such as social anxiety disorder only with the CBT (cognitive-behavioral therapy) you will be leaving aside the anguish and therefore it will probably won't have effect as a long term plan.
With a antidepressant solely based treatment, you will be leaving aside the cognitive part and therefore it won't have a long term effect neither.
