聯合國政府間生物多樣性和生態系統服務科學政策平台（IPBES）今天指出，對農作物授粉至關重要的眾多蜜蜂、蝴蝶和其他物種面臨絕跡威脅，這對全球主要作物及生物多樣性構成威脅。
根據IPBES所做評估：「歐洲西北部和北美眾多野生蜜蜂和蝴蝶正以地方及地區性規模，大量減少，多樣性也不斷縮減。」
評估報告指出，全球其他地區也發現授粉者數量減少。授粉者還包括龐大的其他昆蟲、蝙蝠、鳥類和其他動物。
決策者面臨的問題是科學家仍不確定最主要的因素為何。
這份全球首個這類評估指出，可能原因包括棲息地喪失、殺蟲劑、汙染、入侵性物種、病原體、氣候變遷，以及廣大農田轉種單一作物，阻礙了生物多樣性。
United Nations: bees, butterflies, reduced threat of global crop
2016-02-26 22:22 Central Kuala Lumpur 26th reports
United Nations intergovernmental science policy platform for biodiversity and ecosystem services (IPBES) said today, crucial for crop pollination by large bees, butterflies and other species are facing extinction threat, that posed a threat to major crops and biodiversity around the world.
According to IPBES assessment: "Northwest Europe and North America many wild bees and butterflies is a local and regional scale, a significant reduction in diversity is also shrinking. 」
Evaluation report pointed out that the rest of the world also found that reducing the number of pollinators. Pollinators also include other large insects, bats, birds, and other animals.
Question for policy makers is a major factor why scientists are still not sure.
The world's first such assessment pointed out that possible causes include habitat loss, pesticides, pollution, invasive species, pathogens and climate change, as well as farms switched to single crops, impeded biological diversity.
