In the final film we look at the bigger picture: Earth's place in space. Our planet is unique in the solar system, perhaps even in the universe.

But now this rare and remarkable planet is facing its greatest challenge – us. The question is, will it survive? |

海洋是地球不可或缺的一份子，皆因海岸線、能量轉移、氣候變化都取決於海洋，說海洋是地球的「血液」亦不為過份。 今集Lain先帶大家到夏威夷，看看海洋如何由風中獲取及儲存能量；之後又去到阿瑪遜，為大家示範海洋怎樣從地心吸力中得到能量。
The oceans are almost as ancient as the planet itself; when you look out over the sea you are looking at a view that is unchanged for billions of years. But the oceans are far more than just huge reservoirs of water. They have transformed our planet. Their brute force carves the coastline. And they can leave an extraordinary legacy.

It has carved the landscape and unleashed terrible catastrophes. It's even changed the course of human evolution. Now it may threaten our future...
Iain is introduced to the world of ice 150m's up a frozen waterfall. His precarious ice climb brings him face to face with one of the most extraordinary substances on Earth. It may only be frozen water, but it has extraordinary power.
When it forms glaciers it has the power to carve through solid rock. Several months of footage compressed into just a few seconds shows a glacier in motion - a sliding river of ice. Iain climbs down into a crevasse in a glacier to show how over several years snow gradually turns into ice... |
