But there are parts of the world that have no seasons. 但是 世界上有些地方却没有四季
and there's no concealing vegetation. 也没有可以隐蔽的植被
and there's no food on these nursery slopes. 而这片产仔的斜坡上没有一点食物
There is no food and no water for them, 它们没有食物 也没有水
Surely no greater ordeal is faced by any animal. 这绝对是动物们经受过的最严酷的考验
