雖然所有列出的選項都有助於物種瀕臨滅絕,但棲息地破壞是主要原因。 像森林砍伐和城市化這樣的人類活動清除了重要的棲息地,使動物沒有生活、繁殖或尋找食物的地方。棕熊不被認為是瀕危動物。 牠們被 IUCN 列為「最不受關注」。 然而,由於氣候變化、盜獵和棲息地喪失,北極熊、亞洲象和獵豹正面臨瀕危。國際自然保護聯盟 (IUCN) 維護紅色名錄。 這個全面的清單詳細說明了各種物種的全球保護狀況,是評估生物多樣性危機的重要工具。小頭鼠海豚,發現於加利福尼亞灣,是最瀕危的海洋哺乳動物。 截至我在 2021 年 9 月的知識截止日期,估計僅剩下不到 20 隻,主要是因為被漁網纏住。當一個物種不再有任何活體成員時,它被稱為「滅絕」。 其他術語——瀕危、脆弱和受威脅——都表示對仍然存在的物種的不同程度的保護關注。白頭海鵰,美國的國鳥,是保護的象徵。 雖然一度因狩獵和殺蟲劑而瀕臨滅絕,但在法律保護和保護措施之後,其數量急劇恢復,證明了這些努力的潛在成功。《瀕危物種法》(ESA) 是美國保護瀕危物種的關鍵法律。 它規定保護瀕危或受威脅的物種,以及保護它們賴以生存的生態系統。“關鍵物種”是指在維持生態群落結構中起關鍵作用的物種。移除此類物種會顯著影響生態系統,導致其組成和功能發生巨大變化。CITES 代表《瀕危物種國際貿易公約》。 這是各國政府之間的一項國際協議,旨在確保全球野生動植物標本的貿易不會威脅到它們的生存。野生動物走廊的主要目的是連接零散的棲息地,並允許物種在它們之間移動。 這有助於尋找食物、配偶和新領地,從而有助於增加生物多樣性和遺傳多樣性。雖然所有這些動物都受到棲息地喪失的影響,但金獅狨猴特別與亞馬遜雨林的森林砍伐有關。 這種色彩鮮豔的小型靈長類動物因農業、伐木和城市發展而失去了大部分棲息地。黑足鼬是第一個被克隆的瀕危物種,目的是增加遺傳多樣性和種群數量。 代孕母親於 2020 年 12 月生下了克隆的雪貂。“就地”保護是指在其自然棲息地保護瀕危物種的過程。 與“異地”保護(例如在動物園中)相比,這種方法優先考慮保護自然生態系統和生物多樣性。目前被列為瀕危物種的亞洲象是最大的陸地哺乳動物。 然而,它的體型並沒有保護它免受棲息地喪失、人與野生動物衝突以及象牙偷獵等威脅。根據最新數據,兩棲動物是受威脅最嚴重的動物群體,超過 40% 的物種被列為瀕危物種。 他們對環境變化特別敏感,面臨棲息地喪失、污染、疾病和氣候變遷的威脅。You scored 0 out of 15You scored 1 out of 15You scored 2 out of 15You scored 3 out of 15You scored 4 out of 15You scored 5 out of 15You scored 6 out of 15You scored 7 out of 15You scored 8 out of 15You scored 9 out of 15You scored 10 out of 15You scored 11 out of 15You scored 12 out of 15You scored 13 out of 15You scored 14 out of 15You scored 15 out of 15
