Bee Decline Could Cause Malnutrition In Developing Countries | ThinkProgress

Many people in developing nations already face a range of challenges, including poverty, pollution, and climate change that’s helping make droughts longer and storms more intense. But according to a new study, residents of developing nations could also soon be struggling with something else: malnutrition fueled by the decline of pollinators around the world.
The study, published this month in the journal PLOS ONE, looked at dietary surveys from women and children in parts of Zambia, Uganda, Mozambique, and Bangladesh. The University of Vermont and Harvard University researchers calculated what percentage of five nutrients — vitamin A, zinc, iron, folate, and calcium — in the women and children’s diets came from foods that are heavily dependent on pollinators (crops such as cocoa and Brazil nuts, for example, rely on bees for pollination). The researchers found that, under a scenario in which all pollinators were removed, up to 56 percent of the people in the areas looked at would be at risk of nutritional deficiencies.
Those deficiencies can go far beyond simply not getting proper nutrition, the report notes: vitamin A deficiency causes 800,000 women and children to die every year, and has been found to roughly double the risk of death from measles, diarrhea, and malaria.
“The take-home is: pollinator declines can really matter to human health, with quite scary numbers for vitamin A deficiencies, for example, which can lead to blindness and increase death rates for some diseases, including malaria,” Taylor Ricketts, a UVM scientists who co-authored the study, said in a statement.
