The Arctic is at the top of the world. It is a huge ocean with frozen snow and ice all year round.

Sadly, as the Earth gets warmer, more and more ice is melting, and it has made some animals homeless.

北极位于世界的最顶端，是一个巨大的海洋，终年被冰雪覆盖。北极熊和北极狐等北极动物通常有着厚厚的皮毛，以保存体内的能量。有趣的是，它们中的许多动物像雪一样白，这样它们可以保护自己。遗憾的是，随着地球变暖，越来越多的冰正在融化，这使得一些动物无家可归。

come up

in one's hands

hunt for

猎取
as a result

结果
Seals are an example of why sea ice matters. Mother seals usually put their babies on ice to feed them before they can hunt for food by themselves. However, as the ice melts more quickly, the first six weeks of the seals' lives are not in their hands any more. They have to get into the cold water earlier. They may not find enough food to eat. Moving ice makes it hard for them to come up for air. As a result, seals are in great danger. If we don't take action, we will let them down.

海豹就是一个说明浮冰为何重要的例子。海豹妈妈通常会把它们的幼崽放在冰上喂养，直到幼崽能够自己捕食。然而，随着冰层融化得越来越快，海豹生命的前六周不再由它们掌控。它们不得不更早地进入冰冷的海水中，可能无法找到足够的食物。漂移的冰块让它们很难浮出水面呼吸。因此，海豹的处境非常危险。如果我们不采取行动，就会让它们失望。
