根據(jù)動物保護(hù)組織世界自然基金會（WWF）發(fā)表的一份重要報(bào)告，全球野生動物數(shù)量在不到50年的時(shí)間里減少了三分之二以上。報(bào)告稱，這種 “災(zāi)難性的下降趨勢” 沒有減緩的跡象，并警告說，大自然正以前所未有的速度遭到人類的破壞。

The report looked at thousands of different wildlife species living in forests, grasslands, rivers, and oceans, across the world. Conservation scientists recorded an average 68% fall in mammals, birds, amphibians, reptiles, and fish since 1970.

這份報(bào)告研究了生活在世界各地森林、草原、河流及海洋中的數(shù)千種野生物種。動物保護(hù)科學(xué)家的記錄顯示，自1970年來，哺乳動物、鳥類、兩棲動物、爬行動物和魚類的數(shù)量平均下降了68%。

They described the decline as catastrophic and clear evidence of the impact humans are having on the planet through burning forests, overfishing the seas and destroying wild spaces. 

科學(xué)家們說動物數(shù)量下降是災(zāi)難性的，也是人類燃燒森林、過度捕撈海洋生物和破壞野生空間對地球造成影響的確鑿的證據(jù)。

But Dr Mike Barrett of WWF-UK says new modelling evidence suggests the tide can be turned if action is taken urgently.

但世界自然基金會英國分會的邁克·巴雷特博士說，新的模型證據(jù)顯示，如果緊急采取行動，就可以扭轉(zhuǎn)這種趨勢。

The report says efforts to protect wildlife must be combined with tackling habitat loss and deforestation. This will mean changes to the way food is produced and consumed, including reducing food waste and moving to healthier diets. 

報(bào)告還指出，保護(hù)野生動物的工作必須與解決棲息地喪失和濫伐森林相結(jié)合。這將意味著改變食物的生產(chǎn)和消耗方式，包括減少食物浪費(fèi)和轉(zhuǎn)向更健康的飲食結(jié)構(gòu)。

閱讀理解：請?jiān)谧x完上文后，回答下列問題。

1. True or false? The fall in wildlife populations can be seen as an impact of human activities.

2. How much decline in mammals, birds, amphibians, reptiles, and fish have conservation scientists recorded since 1970?

3. According to Dr Mike Barrett, how can we turn the tide?

4. What should we consider when protecting wildlife, according to the report?

答案

1. True or false? The fall in wildlife populations can be seen as an impact of human activities.
True. Scientists described the fall as clear evidence of the impact humans are having on the planet through burning forests, overfishing the seas and destroying wild spaces.

2. How much decline in mammals, birds, amphibians, reptiles, and fish have conservation scientists recorded since 1970?
Conservation scientists recorded an average 68% fall in these animals since 1970.

3. According to Dr Mike Barrett, how can we turn the tide?
Dr Mike Barrett says new modelling evidence suggests the tide can be turned if action is taken urgently.

4. What should we consider when protecting wildlife, according to the report?
The report says the efforts to protect wildlife must be combined with tackling habitat loss and deforestation.
