Ninety percent of global industrial crops rely on bee pollination. The reduction of the bees will lead to biological chain breaks. When the bees stop pollinating, there will be no plants, animals. And mankind will face food shortages and cannot survive.

Human will have to pay the price that is hard to imagine.
