Drought and warfare are the major causes of world starvation, not a lack of food. true or false?

That statement is true.

Explanation:

All countries in the world rely on agricultural field in order to fulfill the majority of their food demand.

Two major things happen because of drought and warfare:

-  the lands and environment near them will be completely destroyed, make it impossible for people to grow their own crops in that area.  This make the agricultural sectors in that area unable to fulfill the demands of the people, which lead to the starvation.

- The people are forced to move to other area that they are not familiar with. The people might not have the ability to obtain jobs in these new area. So not only they cannot produce their own food, they also do not have the resources/capital to trade with other countries.

its a hope it good luck
