2001年,美国中西部到大湖地区,经历了一次由于蜜蜂大量减少而造成的灾难。深受其害的威斯康星州农民抱怨说,因为可恶的冷冬,使得蜜蜂都冻死了,结果他们的农作物因授粉不充分而大量减产。对此,一些科学家认为这是地球进入第五次冰期的表现。 In 2001, the Midwest region of the United States and the Great Lakes region experienced a catastrophe caused by a significant reduction in bees. Worried Wisconsin farmers complained that the bees were frozen to death due to the odious cold winter. As a result, their crops were greatly reduced due to insufficient pollination. In response, some scientists believe that this is the performance of the Earth entering the fifth ice age.
