地球大堡礁
鲸鱼、魔鬼鱼和鲸鲨都是食用浮游生物维生的海中庞然大物，由于这些藻类均产生氧气，同时储存地球四成的二氧化碳；巨型海鱼吞噬这些美食，等于将碳困在它们体内，直到生命尽头，还可以将危害生态平衡的物质深藏海底。每头鲸鱼一生吸收的碳含量，相当于地球上的一千树的吸收量，故此，此类巨型动物的存在，对生态平衡极有禆益。
本集节目带大家追随科学家和研究员的步伐，上天下海以求近距离接触巨型深海动物。水升流及的藻群出现，都是令人兴奋的鲸踪预告。识别并长期追踪它们，可为保育大堡礁制订更具战略性的方案。
Whales, manta rays, whale sharks are all eaters of animal plankton or small fish, themselves huge consumers of vegetable plankton. These marine algae produce half of the oxygen on earth and capture 40% of the carbon dioxide.But the global role of the Mastodonts is hardly believable. By swallowing plankton and the small animals that feed on them, these giants capture and store carbon in their fat. When they die, they sink into the abyss where the carbon remains trapped for thousands of years. For example, one whale captures as much carbon each year as a thousand trees.
These giants are real allies in regulating the climate and restoring reef productivity. The programme for identifying these new feeding areas is easily reproducible in all the areas concerned around the world.
