SDGs 14
Life Below Water 保育海洋生態

The world’s oceans – their temperature, chemistry, currents and life – drive global systems that make the Earth habitable for humankind. How we manage this vital resource is essential for humanity as a whole, and to counterbalance the effects of climate change.

Over three billion people depend on marine and coastal biodiversity for their livelihoods. However, today we are seeing 30 percent of the world’s fish stocks overexploited, reaching below the level at which they can produce sustainable yields.

Oceans also absorb about 30 percent of the carbon dioxide produced by humans, and we are seeing a 26 percent rise in ocean acidification since the beginning of the industrial revolution. Marine pollution, an overwhelming majority of which comes from land-based sources, is reaching alarming levels, with an average of 13,000 pieces of plastic litter to be found on every square kilometre of ocean.

The SDGs aim to sustainably manage and protect marine and coastal ecosystems from pollution, as well as address the impacts of ocean acidification. Enhancing conservation and the sustainable use of ocean-based resources through international law will also help mitigate some of the challenges facing our oceans.

世界上的海洋--它們的溫度、化學、洋流和生命--驅動著全球系統，使地球適合人類居住。我們如何管理這一重要的資源，對整個人類來說是至關重要的，對抵消氣候變化的影響也是如此。

超過30億人依靠海洋和沿海的生物多樣性為生。然而，今天我們看到世界上30%的魚類資源被過度開發，達到低於可持續產量的水平。

海洋還吸收了人類產生的大約30%的二氧化碳，自工業革命開始以來，我們看到海洋酸化的程度上升了26%。海洋污染，絕大部分來自陸地，正達到令人震驚的程度，平均每平方公里的海洋上有13000個塑料垃圾。

可持續發展目標旨在可持續地管理和保護海洋和沿海生態系統免受污染，並解決海洋酸化的影響。通過國際法加強對海洋資源的保護和可持續利用，也將有助於緩解我們海洋面臨的一些挑戰。
