Goal 14: Life below Water. 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.

Explain this:

Goal 14: Life below Water. 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 kilometer 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.
