参考解析：

细节理解题。根据第四段第一、二句“Extreme weather and reckless development are plotting against the rain forest in ways that scientists have never seen. Trees need more water as temperatures rise, but the prolonged droughts have robbed them of moisture, making whole forests easily cleared of trees and turned into farmland”可知，极端天气和不计后果的发展正在以科学家从未见过的方式密谋破坏热带雨林。随着气温的上升，树木需要更多的水分，但长期的干旱剥夺了树木的水分，使得整个森林很容易被砍伐，变成了农田。由此可知，由于全球变暖导致的降雨量减少使雨林变成农田变得更加容易。故选C。
