Insect numbers have plunged by half in some parts of the world due to climate change and intensive agriculture, a study has found.

一項(xiàng)研究發(fā)現(xiàn)，受氣候變化和集約農(nóng)業(yè)的影響，世界部分地區(qū)的昆蟲數(shù)量已減半。

The combined pressures of global heating and farming are driving a "substantial decline" of insects across the globe, according to UK researchers.

英國研究人員發(fā)現(xiàn)，全球變暖和農(nóng)耕的雙重壓力正導(dǎo)致全球各地的昆蟲數(shù)量“劇減”。

They say we must acknowledge the threats we pose to insects, before some species are lost forever.

研究人員表示，人類必須承認(rèn)自己給昆蟲造成的威脅，否則一些物種將會永遠(yuǎn)消失。

But preserving habitat for nature could help ensure vital insects thrive.

但是，保護(hù)昆蟲的自然棲息地能幫助一些重要昆蟲繁衍生息。

Lead researcher, Dr Charlie Outhwaite of UCL, said losing insect populations could be harmful not only to the natural environment, but to "human health and food security, particularly with losses of pollinators".

倫敦大學(xué)學(xué)院首 席研究員查莉·奧斯維特博士指出，昆蟲數(shù)量減少不僅對自然環(huán)境有害，而且會危及“人類健康和食品安全，傳粉昆蟲數(shù)量減少的危害尤其大”。

"Our findings highlight the urgency of actions to preserve natural habitats, slow the expansion of high-intensity agriculture, and cut emissions to mitigate climate change," she added.

她補(bǔ)充道：“我們的發(fā)現(xiàn)凸顯了采取措施保護(hù)自然棲息地、減緩高強(qiáng)度農(nóng)業(yè)生產(chǎn)的擴(kuò)張以及減排和減緩氣候變化的迫切性�！�

Plummeting populations of insects around the world - a so-called "insect apocalypse" - have caused widespread concern.

世界各地昆蟲數(shù)量劇減——所謂的“昆蟲末日”——引發(fā)了普遍的擔(dān)憂。

However, scientific data gives a mixed picture, with some types of insects showing drastic declines, while others are staying steady.

不過，科學(xué)數(shù)據(jù)反映的情況好壞參半，某些種類的昆蟲數(shù)量急劇減少，而其他種類的昆蟲數(shù)量卻保持穩(wěn)定。

In the latest study, the researchers pulled together data on the range and number of nearly 20,000 insect species, including bees, ants, butterflies, grasshoppers and dragonflies, at about 6,000 different locations.

在這項(xiàng)最 新的研究中，研究人員在約6000個(gè)不同地點(diǎn)收集了近2萬種昆蟲活動(dòng)范圍和數(shù)量的數(shù)據(jù)，其中包括蜜蜂、螞蟻、蝴蝶、蚱蜢和蜻蜓。

In areas with high-intensity agriculture and substantial warming, insect numbers have plunged by 49% and the number of different species by 27%, compared with relatively untouched places that have so far avoided the most severe impacts of climate change, according to the research, published in Nature.

發(fā)表在《自然》雜志上的這篇研究報(bào)告指出，和氣候變化影響最輕微、耕作相對較少的地區(qū)相比，在高強(qiáng)度農(nóng)業(yè)生產(chǎn)為主和氣候變暖顯著的地區(qū)，昆蟲數(shù)量減少了49%，昆蟲種類減少了27%。

But the researchers said there was some cause for hope in that setting aside areas of land for nature created a refuge for insects, which need shade to survive in hot weather.

但是研究人員表示，那些自然的“保留地”給炎熱天氣下需要綠蔭才能存活的昆蟲營造了庇護(hù)所，給昆蟲的生存提供了一線希望。

"Careful management of agricultural areas, such as preserving natural habitats near farmland, may help to ensure that vital insects can still thrive," said Dr Tim Newbold, also of UCL.

同樣來自倫敦大學(xué)學(xué)院的蒂姆·紐博爾德博士表示：“農(nóng)業(yè)區(qū)的精細(xì)化管理，比如保護(hù)農(nóng)田附近的自然棲息地，或許有助于保證重要昆蟲的存活。”

Study researcher, Peter McCann, added: "We need to acknowledge how important insects are for the environment as a whole, and for human health and wellbeing, in order to address the threats we pose to them before many species are lost forever."

參與該研究的彼得·麥肯補(bǔ)充道：“我們需要承認(rèn)昆蟲對整體環(huán)境以及對人類健康和幸福的重要性，從而積極應(yīng)對我們給昆蟲造成的威脅，以免許多昆蟲就此永遠(yuǎn)消失�！�
