A big conservation game for freshwater ecosystems6 in South Africa.
这是南非淡水生态系统的一场庞大的保护游戏。
The stability of our planet is intimately linked to having healthy, functioning ecosystems, whether it's the forests that take a lot of their carbon dioxide out of our atmosphere or the freshwater ecosystem5 that really feed those forests and allow them to grow.
我们星球的稳定与健康运转的生态系统密切相关，无论是从大气中吸收大量二氧化碳的森林，还是真正为森林提供食物并让它们生长的淡水生态系统。
It's all connected and it's really in our best interest to ensure that all of these different kinds of ecosystems stay as healthy as possible for as long as possible.
