 Read the passage given below and complete the statements that follow with the help of the 

given options. 

Since 2006, commercial colonies of bees used to make honey and pollinate crops have been 

collapsing. The loss of bees is a major threat to agriculture. The use of industrial scale methods in 

agriculture seems to be one of the main causes of the crisis. Meanwhile, wild bee species are also 

collapsing due to the destruction of their habitats. These bees also play a vital role in pollinating 

crops and plants generally. According to scientists, bees pollinate more than 70% of the crop 

species that supply 90% of the world's food. Given that the world's population is rapidly growing, 

more bees are needed to pollinate food crops. Scientists are calling for significant changes to how 

humans manage the planet so that honeybees survive and the world's food sources are protected. 

Scientists worldwide are joining forces to pressure governments to implement measures to restore 

bee populations. The strategies being proposed include incentives that encourage farmers and 

landowners to restore habitats that are friendly to pollinators, stringent controls on chemical use 

and manufacture, and stricter quarantine measures between countries. The collapse of honeybee 

colonies is a worldwide phenomenon and this collapse is likely to continue.
