一个世纪前，大部分的海洋生态环境很健康。而仅仅50年后，过度捕捞和污染摧毁了世界各地大量的海洋生物。大量例如太平洋蝠鲼等之前都很健康的种群永远地消失了。
本片带我们来到了墨西哥一片遥远的群岛。这里的海洋环境仍然能够用“富足”“繁荣”“完美和健康”这些词汇来描述。被联合国教科文组织宣布为世界遗产的雷维拉吉杰杜群岛仍然能够表明，我们保护海洋生物多样性的希望仍然存在。
The Legacy is a mouthful of oxygen when so much of today’s environmental reality tells us we are drowning. A century ago, most marine ecosystems were healthy and exploding with life, yet in just 50 years, overfishing and pollution have destroyed marine life populations in many parts of the planet. Several previously healthy populations of species, like the Giant Pacific Manta Ray off the Gulf of California, have disappeared altogether.
The Legacy reminds us not to despair. The film takes us to a remote archipelago in Mexico where words like “abundance”, “thriving”, and “perfect and healthy populations” are still being used to describe a marine environment. Declared a World Heritage site by UNESCO in 2016, the Archipelago of Revillagigedo is evidence that the ocean’s biodiversity, and our hope, is not yet lost.
