黑熊和电视中毒

今年夏天,在离我们仅几公里外的美国西部蒙大拿乡村,每当一只黑熊突然从树林里跑出来,住在那里的朋友就不得不中断用餐,躲到屋子里,看着它走近野餐桌,把盘子舔得干干净净,再喝下两罐啤酒。

接下来几天里,那只熊又掀翻了两个邻居的垃圾桶,并且吓坏了宠物和儿童。美国森林局的护林员们准备了一个笼子,放进了一些咸肉,很快就捉住了这头熊,把它运到了30公里外的荒郊野地中。这头熊被放走前身上做上了标记,表明它曾经找过麻烦。护林员说:"不幸的是,往往是我们的卡车还没回来,熊就已经回来了。一旦尝到了咸肉和啤酒的滋味,就没法再把它赶走了。" 如果做过标记的熊回来捣乱被抓住两次以上,护林员就有权力射杀它。

一只发现了美味的动物抵制不了再次轻易获得美味的诱惑,我们都会为它感到遗憾。除非待在树林里以传统的方式捕猎食物,否则它的生命就已经进入了倒计时,这一点黑熊并不清楚。可那头黑熊是按照自然选择在它基因中种下的智慧来采取行动:富含蛋白质和糖的食物非常有益,而且获取食物消耗的能量越少越好。
