在井壁旁(飲水)的母獅 Lioness at Borehole, South Africa

喀拉哈里大羚羊國家公園里，一頭母獅子正在一個巖石圍起的水塘邊飲水，這個公園建在南非北部開普省的一片3,700平方英里(9,600平方米)的沙漠之中。在二十世紀之交，南非的獅子遭到大肆捕殺，幾乎消失殆盡。但在十九世紀九十年代建立的首個國家動物保護區，已取得了顯著的成效。

A lioness drinks from a rock-ringed borehole in Kalahari-Gemsbok National Park, a 3,700-square-mile (9,600-square-kilometer) slice of desert in South Africa’s Northern Cape Province. Lions had all but disappeared from South Africa by the turn of the 20th century due to unbridled hunting, but the seeds of a remarkable comeback were planted in the 1890s with the country’s first game reserves.
