The journal reported that global warming is destroying coral and that loss of top predator is bringing trouble to the ocean ecosystems. Oceans are a key driver of the climate processes that make Earth inhabitable and fish is a vital source of protein for people. For people living along coastlines of tropical developing countries ear their livelihood from the sea.
Now with the rising of global warming people are killing their own oceans. According to oceanographer Sylvia Earle about 100 million tons of wildlife are pulled from the sea annually. Commercial fishing boats catch virtually everything that swims by in gill nets that act as invisible underwater fences or on 60-mile longlines. These fishing boats accidentally killed young or low-value fish, seabirds, marine mammals and sea turtles, which means about 30 million tons of wasted life.
It is fact that innovative fishing methods are rapidly emptying the sea, disrupting food chains fine-tuned over millions of years. In this process the easy-to-catch dinner table fishes are eliminating fastly. The methods also push fishing operations farther out into the deep ocean where species are more fragile. Even the heavy nets used by industrial bottom trawlers ravage crucial habitat, ripping up sea grasses and coral forests that are up to 2,000 years old.
All these make the quality of water poorer which would pollute the atmosphere of the sea. Boris Worm, a marine biologist, in his research says that all commercial seafood species could collapse within 40 years due to overfishing, loss of habitat, and pollution. World’s developed nations have granted billion dollars as subsidies to support the rapacious fishing practices that threaten the world’s fish stocks.
