Why is biodiversity loss in insect pollinators considered an imminent threat to global food security?
Answer and explanation
Correct answer: C. most staple crops rely on animal pollination
- Step 1: More than 75% of global food crop types, including nutrient-dense fruits, vegetables, and nuts, depend directly on animal pollinators. The collapse of wild bee and insect populations undermines agricultural yields, threatening worldwide food security and nutritional health. Answer: most staple crops rely on animal pollination. Why not the others: "agricultural insect pests consume more than half of cereal grain reserves" characterizes crop pests rather than beneficial pollinators that assist plant reproduction; "pollinators generate chemical fertilizer" falsely attributes industrial synthetic nitrogen production to biological pollinating insects; "bees filter atmospheric greenhouse gases" confuses biological pollination with biogeochemical carbon and methane cycling.
