Read the passage about the fluoridation of drinking water.Since the early 1960s, fluoride has been added to many sources of drinking water to prevent cavities in teeth. This is called fluoridation. There are some who say that this is unnecessary and increases the risk of cancer.In 1993, the Subcommittee on Health Effects of Ingested Fluoride of the National Research Council, part of the National Academy of Sciences, conducted an extensive study about the link between fluoridated drinking water and increased cancer risk. The study included data from more than 50 human disease studies and six animal studies. The Subcommittee concluded that none of the data showed a link between fluoridated drinking water and cancer. A 1999 report by the CDC supported these findings. The CDC report concluded that studies so far have produced "no credible evidence” of a link between fluoridated drinking water and an increased risk for cancer.

Cornell University recently conducted a study that estimated that honeybees pollinate more than $14 billion worth of crops each year. The study suggested that nearly seventy-five percent of all global crops that are grown for food, fiber, beverages, condiments, spices, and medicines are pollinated. Produced with the help of pollinators, agricultural products including legumes, vegetables, fruits, berries, nuts, herbs, spices, oils, seeds, grains, clover, and cotton make a significant contribution to the economy. As the human population increases, so does the demand for pollination; sadly, the honeybee population is decreasing. Within the past thirty years, parasites, predators, and disease have weakened both wild and managed populations of honeybees. In fact, around the globe, honeybees are being decimated by an epidemic known as colony collapse disorder (CCD). According to this article, who collected information to research the honeybees?
