In early 2016, the United Nations released a report on the biodiversity of pollinators around the world. According to the report, two out of five species of invertebrate pollinators (primarilybees, but also butterflies and other insects) now face extinction, and one in six of the vertebrate pollinators (birds) do as well. Four causes have been identified for the loss of biodiversity:loss of basic habitat, simplification of the landscape to promote single crops, indiscriminate use of pesticides, and the urbanization of landscapes. Which of the following activities would helprestore pollinator populations in the United States?A.Requiring farmers to produce wheat instead of corn or potatoesB.Encouraging farmers to enhance their farms by planting flowering hedgerows and natural nesting sites for pollinatorsC.Making it illegal to produce or sell honey products within the United StatesD.Requiring farmers to use pesticides all year long, not just when flowers are blooming
