Without sound conservation and management measures, fisheries will quickly become depleted and a basic component of global food security will be lost.
Sentiment: NEGATIVE
Remove the predators, and the whole ecosystem begins to crash like a house of cards. As the sharks disappear, the predator-prey balance dramatically shifts, and the health of our oceans declines.
One fifth of human kind depend on fish to live. Today now 70 percent of the fish stock are over-exploited. According to FAO if we don't change our system of fishing the main sea resources will be gone in 2050. We don't want to believe what we know.
Wild fish are under threat of extinction because they're hunted to feed us. Yet land animals that we farm are under no threat of extinction. Shifting from hunting fish to farming fish - where the farmers have the incentive to keep their stocks healthy - could do a tremendous amount of good for wild fish.
The crisis of the fisheries is similar to our economy. This is not one fishery failing, but the whole system.
European fisheries are a disaster. The American fisheries are well-kept.
Marine scientists predict that by 2050 there will be no more large fish left in the ocean if we don't change our relationship with the sea.
People need to look at wildlife conservation in its totality. As soon as you lose the apex predator, it has harmful consequences right down the food chain.
If you look at the carrying capacity of agricultural areas throughout the world, their ecological habitats are changing. So I think we're looking at - in our lifetime - great collapses of food services.
80 percent of our global fish stocks are fully exploited, overly exploited or have collapsed. Two billion people rely on the oceans for their primary source of protein.
Without sharks, you take away the apex predator of the ocean, and you destroy the entire food chain.
