The earth is rich in biodiversity with millions of different species of plants and animals.
地球擁有豐富的生物多樣性，孕育著數以百萬計不同種類的動植物。

However, many species are disappearing at an alarming rate.
然而，許多物種正以驚人的速度消失。

Biodiversity is reduced when ecosystems are modified and habitats of plants and animals are destroyed.
當生態系統遭到改變、動植物的棲息地受到破壞時，生物多樣性就會隨之減少。

Many scientists view the current wave of species extinctions as unrivaled since the disappearance of the dinosaurs, more than 65 million years ago.
許多科學家認為，當前的物種滅絕浪潮，其規模之大是自6,500多萬年前恐龍消失以來前所未見的。

Currently, around 11,000 species of plants and animals are at risk of vanishing forever – this includes over 180 mammals.
目前，約有11,000種動植物面臨永遠消失的風險，其中包括超過180種哺乳動物。

Many species cling to survival.
許多物種正掙扎著求生存。

Found only in China, the giant panda's habitat has been decimated – the bamboo forests where the pandas make their home are being destroyed rapidly.
僅分布於中國的大貓熊，其棲息地已遭嚴重破壞，貓熊賴以為家的竹林正被迅速摧毀。

It is estimated that as few as 1,600 giant pandas remain in the wild today.
據估計，現今野生大貓熊的數量僅剩約1,600隻。

In the Arctic, the polar bear's icy habitat is diminishing as a result of global warming, and its survival is at risk.
在北極地區，北極熊的冰雪棲息地因全球暖化而逐漸縮減，其生存正受到威脅。

And in Central and East Africa, which have endured decades of civil war, the mountain gorilla population now totals just over 700 individuals.
而在歷經數十年內戰的中非與東非地區，山地大猩猩的總數如今僅剩700多隻。

If present trends continue, humanity stands to lose a large portion of its natural inheritance.
如果目前的趨勢持續下去，人類將會失去一大部分的自然遺產。

Extinction is one environmental problem that is truly irreversible – once gone, these species cannot be brought back.
滅絕是一個真正不可逆轉的環境問題，這些物種一旦消失，就再也無法挽回。

And the one species that is causing this phenomenon is the same one that can stop it.
而造成這個現象的唯一物種，也正是能夠阻止這一切的同一個物種（指人類）。

What can be done?
我們能做些什麼呢？

World Wildlife Fund (WWF), the global conservation organization, has been working since 1961 to conserve the diversity of life on earth.
全球保育組織「世界自然基金會」（WWF）自1961年以來，一直致力於保護地球上的生命多樣性。

In recent years, WWF has advanced giant panda conservation by training more than 300 panda reserve staff and local government officials, working with the community to help save habitat and guard against illegal hunting.
近年來，世界自然基金會透過培訓超過300名貓熊保護區工作人員及當地政府官員，並與社區合作協助拯救棲息地及防範非法狩獵，推動了大貓熊的保育工作。

By spreading awareness of the danger of carbon dioxide emissions, and by promoting the use of renewable energy resources such as wind and solar power, WWF is trying to head off the effects of global warming, giving the polar bear a chance to survive.
透過宣導二氧化碳排放的危害，並推廣風力與太陽能等再生能源的使用，世界自然基金會正設法遏止全球暖化的影響，為北極熊爭取一線生機。

With the help of other organizations in Africa, WWF has established a system to monitor the status of mountain gorillas to address potential threats.
在非洲其他組織的協助下，世界自然基金會建立了一套系統來監測山地大猩猩的生存狀況，以應對潛在的威脅。
