According to a new study, Climate Change will significant oceans across the world and result in a completecollapseof food chain.

The study by researchers at Adelaide Universityin Australia showed that increasing level of ocean acidification and warming might reduce the number of important species and also impact their diversity and this might impact the ecosystems across the world.

University of Adelaide associate professor Ivan Nagelkerken said that the warmer water will increase metabolic rates of animals and this will increase competition for limited food available. He said that there might be a collapse of speciesfrom the top of the food chain. He added that lesser number of species might affect humans especially people living in the coastal areas and relying primarily on fishing.

The study said that food chain collapse due to greenhouse gas emissions will pact eating fish. He explained this will mean that higher the fish will be on the food chain; the more it will be impacted. He pointed out these are fishes that are popularly eaten like tuna. Data showed that the global average temperature has warmed by 0.11 degree celsius per decade over thepreviosu four decades in the upper 75 metres of the ocean.
