全球气候变化，令海洋高速升温。最新研究估计，海洋每秒钟所吸收的热能，相当于五个原子弹爆炸所释放出的能量。海洋储存着九成因人为全球暖化而产生的热能，而2020年更是全球海洋录得史上最高温的一年。
一项报告指出，塑胶污染是海洋生物大灭绝的另一主因；估计现时全球海洋里共有15至51兆件塑胶垃圾，从赤道到南北两极、北极冰原到海床都无一幸免。
地球上并无任何一平方里的表面海洋未受到塑胶污染，人类活动对菲律宾绿海龟带来了什么影响？
化石燃料业界计划在未来十年内，将塑胶产量增加四成；新研究更指出，气候变化可能会令海中六成鱼类物种灭绝。当高温杀死珊瑚礁，鱼类也会无法繁殖；鱼类绝种的话，人类还能生存吗？
节目会走访菲律宾各地，与一众专家和科学家见面，见证他们如何努力保护栖息地，从而拯救绿海龟。绿海龟已被列为濒危物种，人类能够力挽狂澜，拯救它们吗？

The world's oceans are now heating at the same rate as if five Hiroshima atomic bombs were dropped into the water every second due to climate change. The ocean contains 90 percent of the heat from human-induced global warming, and the year 2020 was the warmest ever measured for the global ocean. 

According to a report, plastic pollution is another reason for the mass extinction of marine life. Studies estimate there are now 15–51 trillion pieces of plastic in the world's oceans — from the equator to the poles, from Arctic ice sheets to the sea floor. 

Not one square mile of surface ocean anywhere on earth is free of plastic pollution. What is the impact of such human activities on the Philippines green sea turtle?  The problem is growing into a crisis. The fossil fuel industry plans to increase plastic production by 40 percent over the next decade. New research suggests that climate change could wipe out 60% of all fish species in the oceans. As the heat kills coral reefs, fishes are unable to reproduce. Can humanity survive without fish? 

We traverse the Philippines to witness the battle to save the green sea turtle as we meet with experts and scientists trying to protect the habitat from human activity. Can the green sea turtle and its ecology which has now been ranked as an endangered species due to climate change be saved?
