参考解析:
细节理解题。根据倒数第二段第一句“but thousands still return each year to traditional breeding grounds”可知,海豹还是愿意返回原来的地方繁殖,无论冰块的现状,C项正确。根据第三段可知,自从1979年开始有卫星记录这个地区的季节性海冰覆盖情况,所以排除A项;根据第五段可知:海豹非常适合应对自然的短期气候变化,但它们可能无法很好地适应短期变化、长期气候变化以及狩猎和副渔获物等其他人类影响的影响,所以排除B项;根据第七段可知,1950年至1972年,加拿大东海岸海豹数量的大幅减少,并在1973年至2000年期间稳步恢复。说明海豹数量是有希望恢复的,所以排除D项,故选C。
