What We Do Defending Our Oceans According to the United Nations,
over 75 percent of the world's fisheries are fully exploited,
over exploited or significantly depleted. Some species have
already been fished to commercial extinction; many more are on
the verge. Greenpeace activists paint 'Stolen Fish' on the hull
of the illegal cargo vessel Binar 4 before occupying it to
prevent the unloading of fish stolen from Guinean waters. Over-
fishing is emptying the seas faster than nature can replenish
it, threatening the food security of hundreds of millions of
people. Destructive fishing, climate change and polluting
industries are threatening the survival of many fish species,
whale and dolphin populations and whole marine ecosystems.
Exploitation off West Africa's coasts West African nations have
some of the richest fishing grounds in the world; yet their food
security is under threat. European and Asian fishing fleets have
moved into West African waters over the past 30 years after
depleting their own fish stocks.
