蜂群崩坏
Honeybees are social insects that live in colonies.蜜蜂是群居的昆虫。
A bee colony consists of a queen bee, male drones and thousands of female worker bees.蜂群由蜂王、雄蜂和成千上万的工蜂组成。
Each colony also contains eggs and immature bees in various stages of development.每个蜂群中还含有处于不同发育阶段的卵和未成熟的蜜蜂。
The number of bees within a colony depends on seasonal changes.蜂群中的蜜蜂数量取决于季节的变化。
A colony's population increases during the warm seasons and decreases during colder seasons.种群数量在温暖季节增加，在寒冷季节减少。
In recent years, many bee colonies have collapsed, or disappeared.近年来，许多蜂群崩溃或消失。
A bee colony collapse occurs when a majority of the bees in a colony disappear and leave behind the queen.当蜂群中的大多数蜜蜂消失并离开蜂王时，蜂群就会崩溃。
Some beekeepers have reported losing 30 to 90 percent of their colonies.一些养蜂人报告说，他们失去了30%到90%的蜂群。
This loss of bee colonies can cause significant problems for farmers who depend on them to pollinate their crops.蜜蜂数量的减少会给依赖它们为作物授粉的农民带来严重的问题。
In some parts of the world a shortage of bees has increased the cost of renting bees by up to 20%.在世界上的一些地方，蜜蜂的短缺使得租用蜜蜂的成本增加了20%。
What has increase the cost of renting bees in some parts of the world? a shortage of bees在世界的某些地方，是什么增加了蜜蜂的租赁成本?蜜蜂短缺
There are several possible causes for bee colony collapse.蜂群崩溃有几个可能的原因。
One possible cause is the use of new pesticides.一个可能的原因是使用了新的杀虫剂。
Other possible causes include infections from viruses, genetic factors, and malnutrition.其他可能的原因包括病毒感染、遗传因素和营养不良。
Changing weather patterns may also play a role as summers get hotter and winters get colder.随着夏季变热、冬季变冷，气候模式的变化也可能起到一定作用。
These changes in weather may weaken the bees, making it more difficult for them to fight infections.这些天气变化可能会削弱蜜蜂的力量，使它们更难抵御感染。

Whatever the cause of colony collapse, it's important to understand that many parts of our world are interdependent.无论蜂群崩溃的原因是什么，重要的是要明白我们世界的许多地方是相互依存的。
Changes that affect one species may have serious effects on other species.影响一个物种的变化可能对其他物种产生严重影响。
A change to our environment can start a chain of events that is difficult to predict.环境的变化会引发一系列难以预测的事件。
In any complex system such as the Earth's environment,small changes can have unforeseen consequences.在任何复杂的系统中，比如地球环境，微小的变化都可能带来无法预料的后果。
The danger of unforeseen consequences is something we all need to understand better.我们都需要更好地理解意外后果的危险。
Things that are interdependent are depend on each other.相互依存的事物是相互依存的。
The Earth's environment is a extremely complex system.地球环境是一个极其复杂的系统。
The number of bees within a colony depends on seasonal changes.蜂群内蜜蜂的数量取决于季节的变化。
In addition to making honey, honeybees help many plants reproduce.除了制造蜂蜜，蜜蜂还帮助许多植物繁殖。
The main idea here is: The Earth's environment is a complex system.
