It's about reaching equilibrium. The system will attempt to balance things and we might not like that balance -- so we'll mess it up some more to try and fix it. The problem is that we (mankind in general) are not satisfied with some parts of the system, so we change things thinking everything will be better. Not so, now the system has to react to reach equilibrium. One thing changes and the system compensates. We get GM corn and lose honeybees, people look for a connection. Nature can play tit for tat and win; nature always wins. We look for results next year, nature looks for balance over eons.
