以下哪一項不是 CITES 對北極熊的看法？
(A) 應禁止獵殺北極熊。
(B) 許多人以獵熊為生。
(C) 北極熊狩獵得到控制。
(D) 它們棲息地的減少與貿易無關。

CITES secretary-general Willem Wijnstekers said, “If we use tiger numbers as a performance indicator績效指標, then we must admit that we have failed miserably.” Human encroaching and illegal trade in tiger parts have contributed to the fall in their numbers from 100,000 at the beginning of the 20th century to around 3,600 today. 

CITES 秘書長 Willem Wijnstekers 說，“如果我們用老虎數量作為績效指標，那麼我們必須承認我們慘敗。” 人類的侵占和老虎器官的非法貿易導致它們的數量從 20 世紀初的 10 萬隻減少到今天的 3600 只左右。

Bans were proposed on legal trading in certain species. Japan is the largest importer of the Atlantic bluefin tuna. The fish is the key ingredient in sushi, a Japanese delicacy. Stocks of this fish have fallen by 75% due to widespread overfishing. Monaco, a European nation, proposed a ban on fishing. The World Wildlife Fund world call for restaurants, retailers零售商, chefs and consumers around the world to stop selling, serving, buying and eating the endangered fish. 
有人提議禁止某些物種的合法交易。 日本是大西洋藍鰭金槍魚的最大進口國。 魚是日本美食壽司的主要原料。 由於廣泛的過度捕撈，這種魚的數量下降了 75%。 歐洲國家摩納哥提出禁漁令。 世界野生動物基金會呼籲世界各地的餐館、零售商、廚師和消費者停止銷售、供應、購買和食用這種瀕危魚類。

The USA proposed a ban on the international sale of polar bear skins. Their population, now between 20,000 and 25,000, could go down by one-third by the year 2050. This is because climate change is destroying their natural habitat. CITES members opposed the ban saying the threat to the habitat was not connected with trade. They also said that polar bear hunting was a regulated activity and that it was a source of livelihood to many people.
美國提議禁止在國際上銷售北極熊皮。 它們的數量目前在 20,000 到 25,000 之間，到 2050 年可能會減少三分之一。這是因為氣候變化正在破壞它們的自然棲息地。 CITES 成員反對該禁令，稱對棲息地的威脅與貿易無關。 他們還表示，北極熊狩獵是一項受監管的活動，是許多人的生計來源。
