1 00:00:10,510 --> 00:00:11,895 The ocean. 2 00:00:11,895 --> 00:00:16,867 99% of the Earth’s living space the atmosphere. 3 00:00:16,867 --> 00:00:23,674 nitrogen, oxygen, carbon dioxide and more. 4 00:00:23,674 --> 00:00:28,996 At the top of the ocean, trillions of microscopic algae. 5 00:00:28,996 --> 00:00:30,697 Phytoplankton. 6 00:00:30,697 --> 00:00:34,301 Different shapes, different sizes, different roles 7 00:00:34,301 --> 00:00:36,887 in the web of life. 8 00:00:36,887 --> 00:00:42,442 Like land plants, phytoplankton need carbon dioxide to build 9 00:00:42,442 --> 00:00:44,161 cellular material. 10 00:00:44,161 --> 00:00:49,349 They also give off oxygen, so much oxygen that one of every 11 00:00:49,349 --> 00:00:55,205 two breaths you take uses oxygen produced by phytoplankton. 12 00:00:55,205 --> 00:00:58,892 But to understand how the ocean and atmosphere interact, and 13 00:00:58,892 --> 00:01:02,396 what that means in terms of global climate change– you need 14 00:01:02,396 --> 00:01:04,915 to look down, from space. 15 00:01:04,915 --> 00:01:08,468 That’s PACE. 16 00:01:08,468 --> 00:01:13,473 And with it, we’ll transform how we see the world.
