Bees play a crucial role on Earth-some even claim that if they go extinct,humanity would be next.So with the dramatic decline in bee population,should we be worried? What happens if the bees all die?
蜜蜂在地球上扮演着重要的角色----甚至有人说如果蜜蜂灭绝了 下一个说是人类,所以 如今迅速减少的蜜蜂数量,是否值得我们担忧?如果蜜蜂灭绝会如何?
Simply put,if a plant produces a flower,you can bet that bees help them reproduce.This long-standing,working relationship evolved with flowers being bright and fragrant to attract bees,and the bees fuzzy,velcro-like bodies helping them to efficiently transfer pollen from the male part of the plant to the female part.
This seemingly simple mechanism is directly responsible for the production of 70% of fruits,vegetables,seeds and nuts that we consume on a daily basis.70% !Which translates into almost $200 billion in global agriculture revenue.This huge responsibility is accomplished by droves of commercial bees,reared by professional beekeepers for the sole purpose of being transported to farms and orchards to pollinate crops.
But since 2006,these hardworking,busy bees have been mysteriously disappearing.This Colony Collapse Disorder has seen an average of 1/3rd of commercial bees abandoning their hives.In fact,some beekeepers have even reported that 90% of their bees have simply buzzed off.In some colonies,mites,viruses and parasites have been to blame,but many are now looking at a class of insecticides called neonicotinoids.
但是 2006年之后,这些勤恳忙碌的蜜蜂不知如何故不断消失减少,蜂群衰竭失调症导致,约三分之一的商业蜂抛弃了它们的蜂房,事实上,有养蜂人报告说,他们蜂房90%的蜜蜂都跑掉了,有些蜂群出问题 是因为螨虫,病毒和寄生虫,但是更多地方可能是受头号杀虫剂新烟新烟碱的影响.
This neurotoxin is used to kill off crop eating insects and pests,but also affects the central nervous systems of bees when they consume contaminated nectar.And since nectar is brought back to hives,the entire colony can be affected,leading to mass confusion and disorientation.
On top of this,other factors such as extremely cold and long winters,a lack of genetic diversity in commercial bees,and less variable nectar in the fields may be at fault.If the trend continues,entire food chains and webs may be at risk.Take almond planets for example;the hulls of these nuts are used as feed for farm cattle and chickens.
Fewer bees means fewer almonds,which could mean declining livestock,and ultimately less milk,cheese,eggs and meat production.Not to mention almonds are used in cereal,baking and many other food products.Beef and dairy cows would also be harshly affected by the vanishing alfalfa fields which are used to harvest hay for cattle.
Looking for a morning buzz?Considering bees pollinate Coffea arabica,whose seeds we grind for coffee,you can count that out.Without bees,our diet would consist of mostly corn,wheat and rice,as they are wind pollinated plants.Like your clothes?Not only is cotton the biggest cash crop in the US,it also makes up about 35% of the world's fiber use.So you can forget those blue jeans,towels,mattresses and high quality paper products.
Simply put,we'd be living in a completely different world without bees,not to mention suffering a substantial economic strain from their disappearance.So while we may not necessarily go "extinct" should the downward trend persist,a world without the buzz of bees would definitely...sting!
简而言之,没了蜜蜂 我们会生活在一个截然不同的世界,更别提蜜蜂消失带来的巨大的经济压力,因此 虽然继续让蜜蜂消失,我们也未必会灭绝,但是一个没有蜜蜂的世界 绝对会让人相当痛苦.
