@i_need_help123  What do you think it is and ill tell you right your wrong? (then I will explain and help you get to the answer)

anonymous · Answer

it cant be anything caused by nature, because nature is nature, perfect, natural and will fix itself. So b and c are out. Using too much fertilizer, and reforestation are left.
Now think about fertilizer:
Man made, waste, poop sometimes.
Now reforestation:
Planting Trees, rebuilding a forest that already existed there. 
Now choose one
