北美五分之一的授粉者,对于15B美元食品生产至关重要,面临灭绝风险,研究发现。 One-fifth of North America's pollinators, crucial for $15B in food production, face extinction risks, study finds.

PNAS的一项研究显示,北美五分之一的授粉者,包括蜜蜂、蝴蝶和飞蛾,面临灭绝的危险。 A study in PNAS reveals that one-fifth of North America's pollinators, including bees, butterflies, and moths, are at risk of extinction. 这项研究评估了美国1 579个授粉者,发现22.5%处于危险之中,而加拿大10%以上面临灭绝。 The research assessed 1,579 pollinators in the U.S. and found 22.5% at risk, while over 10% in Canada face extinction. 蜜蜂的风险最高,34.7%的被研究物种面临风险。 Bees have the highest risk, with 34.7% of studied species at risk. 污染者每年为粮食生产贡献超过150亿美元,但面临生境丧失、杀虫剂、气候变化和疾病的威胁。 Pollinators contribute over $15 billion to food production annually but face threats from habitat loss, pesticides, climate change, and disease.
