Scientists studying the disorder believe a combination of factors could be making bees sick. Including pesticide exposure, parasitic mites, inadequate food supply and a new virus that targets the bees' immune systems. More research is needed to determine the exact cause of the bees' disappearance. In addition, a number of other Federal agencies and State departments of agriculture, universities, and private companies are conducting studies to seek the cause or causes of CCD. This issue has proved to be such an important problem to solve, even the president has had press releases to spread the importance of bees to America and the world. .
Monoculture is the practice of only growing one crop for farming. Farmers in today's day and age are growing only one crop, as compared to a few decades ago when farmers would grow a few different types of crops. This affect the way bees pollinate because there is only one specific type of crop and then the crop goes away for a set amount time in the off season. The main reasons for global bees-decline are industrial agriculture, parasites/pathogens and climate change. The loss of diversity in farming, destruction of habitat and lack of forage due to monocultures and bee-killing pesticides are particular threats for honeybees and wild pollinators. It is becoming increasingly evident that some insecticides, at concentrations applied routinely in the current chemical-intensive agriculture system, exert clear, negative effects on the health of pollinators both individually and at the colony level. The observed, sub-lethal, low-dose effects of insecticides on bees are various and diverse in many way. Pollinators, managed or wild, cannot escape the various and massive impacts of industrial agriculture: they suffer simultaneously from the destruction of natural habitats caused by agriculture, and, because pollinators' natural ranges inevitably overlap with industrial farming landscapes, the harmful effects of intensive agricultural practices.
