《蓝色星球》是一部关于海洋生物的纪录片，其中包含了许多令人震撼的镜头和深刻的描述。以下是一些从该纪录片中摘抄的英文句子：

1. "We all have a common home. She provides us with enough food, enough water and enough living room. We get everything from nature to live better, but we don't do anything to protect her. Now the air is polluted, the earth is poisoned, water is unsafe to drink and rubbish is burying the civilization that man owns."

2. "Ocean World is dwarfed by the vast expanse of the open ocean. It is the biggest animal that has ever lived on our planet. A blue whale, 30 metres long and weighing over 200 tonnes."

3. "The oceans, seemingly limitless, invoke in us a sense of awe and wonder and also, sometimes, fear. They cover 70% of the surface of our planet and yet they are still the least explored."

4. "In the course of making Blue Planet II, we've explored every corner of the underwater world. We've encountered extraordinary animals and discovered new insights into how life is lived beneath the waves."

这些句子不仅展示了《蓝色星球》中的一些壮观景象，还反映了人类对海洋生态系统的影响和保护的必要性。
