Task: Question Answering
Input (English): Background Paragraph: Desertification is a type of land degradation in which a relatively dry area of land becomes a desert, typically losing its bodies of water as well as vegetation and wildlife.[2] It is caused by a variety of factors, such as through climate change (particularly the current global warming)[3] and through the overexploitation of soil through human activity.[4] When deserts appear automatically over the natural course of a planet's life cycle, then it can be called a natural phenomenon; however, when deserts emerge due to the rampant and unchecked depletion of nutrients in soil that are essential for it to remain arable, then a virtual "soil death" can be spoken of,[5] which traces its cause back to human overexploitation. Desertification is a significant global ecological and environmental problem with far reaching consequences on socio-economic and political conditions.[6]. 
Story: People in Iran used extensive grazing, fell most of their trees so they have lots of problems with desertification. Iraq took a more mindful approach to land use, they preserved native species, planted trees and didn't overgraze the land. 
Question: Which country destroyed more land through overexploitation?
Output (English): Iran.
