Being significant contributors to the reproduction of various plants, bees are one of the most integral pollinators in nature. According to the United Nations Food and Agriculture Organization (FAO), bees are responsible for pollinating 75% of the world’s crops. However, they are rapidly dying. Within a 3-month period, Brazil has lost over 500 million bees, leaving the future of our food in question.
It is reported that 500 million bees were found dead by beekeepers in four Brazilian states — 400 million in Rio Grande do Sul, 7 million in São Paulo, 50 million in Santa Catarina, and 45 million in Mato Grosso do Sul.
The data has been collected from December 2018 to February 2019.
The vice president of Brazil’s Rio Grande do Sul beekeeping association, Aldo Machado, told Bloomberg that within 48 hours, tens of thousands of honey bees in his colony died after falling sick. “As soon as the healthy bees began clearing the dying bees out of the hives, they became contaminated. They started dying en masse,” he said.
The researchers put blame on this devasting situation to the high increase of pesticide use. Since January Brazil has approved almost 300 new pesticides for use on crops.
Researchers have found pesticide traces, such as fipronil, in some of the dead bees. It is an insecticide which is commonly used for veterinary purposes such as helping to get rid of fleas and ticks.
Not only does this mean that pesticides are harmful to bees, but the effect on humans is also worrying.
