蜜蜂“集体失踪”手机是祸首?

一提起蜜蜂，人们很容易想起它们在田间飞来飞去、勤劳地进行授粉的画面。然而，在美国和欧洲许多国家，目前却出现了一件奇怪的事情：大量蜜蜂神秘地“集体失踪”。

一些科学家猜测，这一罕见的现象是由人类大量使用手机等电子产品造成的。由于手机通信网络和辐射影响其导航系统，本来非常恋家的蜜蜂再也无法找到回家的路，最终选择了大批的离去。      

科学家警告说，蜜蜂的大量失踪将使人类生态系统的未来遭遇很大威胁，农作物可能因此大量减产，人类最终可能面临大规模的食物短缺。在我们吃的食物中，有大约三分之一都在某种程度上受到蜜蜂数量的影响。如果蜜蜂灭绝的话，农作物、草料将无法生长，家畜也将因此灭绝。 

人们经常引用爱因斯坦的这句名言；“如果蜜蜂在地球上消失，人类在4年左右也会全部消失。”

The blue of the sea is caused by the scattering of sunlight by tiny particles suspended in the water. Blue light, being of short wavelength, is scattered more efficiently than light of longer wavelengths. Although waters of the open ocean are commonly some shade of blue, green water is commonly seen near coasts, especially in tropical or subtropical regions. This is caused by yellow pigments being mixed with blue water. Phytoplankton are one source of the yellow pigment. Other microscopic plants may color the water brown or brownish-red. Near the shore, silt or sediment in suspension can give water a brownish hue. Outflow of large rivers can often be observed many miles offshore by the coloration of suspended soil particles.
Marine phytoplankton (Greek for "plant wanderers") are microscopic single-celled plants that include diatoms, dinoflagellates, coccolithophorids, green algae, and blue-green algae, among others. The growth of these organisms, which photosynthesize light, depends on a delicate balance of nutrient enrichment via vertical mixing, which is often limited by the availability of nitrogen and light. Diatoms are one-celled plants with patterned glass coverings. Each glass, or silicon dioxide box, is ornamented with species-specific designs, pits, and perforations making them popular with microscopists and, more recently, electron scanning microscopists.

The growth of phytoplankton is often limited by the availability of ______.

A．oxygen

B．hydrogen

C．nitrogen

D．carbon dioxide
