What Happens If All The Bees Die.png
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.

简而言之 如果一棵植物开了一朵花,那么蜜蜂肯定会帮它们繁殖,自古以来,它们有着固定的分工,花儿负责开得娇艳芬芳吸引蜜蜂,而蜜蜂那长着毛像魔术贴一样的身体则负责,将植物的花粉从雄花上移到雌花上.

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.

这个看似简单的机制正是,70%水果,蔬菜,种子和坚果生产的直接原因,而这些食物是我们的日常所需,70%!就全球农业收益而言,相当于2000亿美金,这个巨大的收益是由一群商业蜜蜂完成的,专业养蜂人唯一的饲养目的就是,桨它们送去农场和果园为庄稼授粉.

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.

这种神经毒素被用于消灭吃庄稼的虫子和害虫,当蜜蜂吸食了被它污染的花蜜时,中枢神经系统就会受影响,花蜜被带回蜂房后,整个蜂群都会受影响,导致大规模的混乱和迷失方向.

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.

另外,其他因素,例如极其漫长的严冬,商业蜂群缺少遗传多样性,田里花蜜种类单一都可能会造成问题,如果继续发展下去,整个食物链食物网都会出问题,以杏仁植物为例 这些坚果的外壳,过去曾用于喂养农场里的牛和鸡.

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.

蜜蜂减少杏仁花也会减少,这意味着家畜也会减少,最终牛奶,奶酪,鸡蛋和肉类都会减少,更不用说 杏仁还广泛用于谷物,烘焙和许多其他食品生产过程,苜蓿田的消失也会大大影响肉牛和奶牛,这种植物收割晒干后用于养牛.

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.

在找清晨活力?考虑到咖啡树是靠蜜蜂传份的,猜猜我们用来磨咖啡的豆子是谁的种子,没有了蜜蜂,我们的主要食物会是玉米,小麦和米饭,它们都是风媒传粉植物,喜欢你的衣物?棉花不仅是美国最重要的经济作物,它还是世界上35%纤维制品的原料.以后就不用惦记牛仔裤,毛巾,床垫,和高品质的纸制品了.

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.
