not in the least concerned

Be like the sun and the meadow, which are not in the least concerned about the coming winter.

要像阳光和草地那样对寒冬的来临全不在乎。

Yet, while not wanting to begrudge the polar bear his ice, we should be at least somewhat concerned at this recent shift in thinking.

然而，虽然我们并不想希望北极熊失去它的冰，我们至少应该对近期的这些意识上的转变有一点担心。

We should be concerned, not primarily because ice is melting (if it is), but because global warming-or at least the idea of it-is responsible for a renewed interest in population control.

我们应该担心的，主要不是冰在融化(就算是吧)，而是全球变暖——或者是担心全球变暖——重新引起了对人口控制的兴趣。
