Explanation:
Maintaining biodiversity is essential for organic waste disposal, soil formation, biological nitrogen fixation, crop and livestock genetics, biological pest control, plant pollination, and pharmaceuticals. Plants and microbes help to degrade chemical pollutants and organic wastes and cycle nutrients through the ecosystem. For example:
Pollinators, including bees and butterflies, provide significant environmental and economic benefits to agricultural and natural ecosystems, including adding diversity and productivity to food crops. As many as one-third of the world’s food production relies directly or indirectly on insect pollination. About 130 of the crops gown in the United States are insect pollinated. Habitat fragmentation and loss adversely affects pollinator food sources, nesting sites, and mating sites, causing precipitous declines in the populations of wild pollinators.
