About 50% of the fish caught in tropical regions. The expected loss of fish populations by 10-40% can seriously damage the economy of Africa, Oceania and other parts of the world.
Experts at the canadian University of British Columbia believe that the climate crisis will cause significant harm to fish populations in tropical regions. In the end, the economy may experience a food crisis, which spread throughout many regions of the world.
The study authors noted that the seafood is the largest international food trade and more than 50% of the world’s fisheries occur in tropical waters. The total value of the annual catch in the tropics is estimated at 96 billion. However, these regions are more likely to suffer from climate change heating up the oceans. Scientists emphasize that from extinction or migration of fishes in a tropical climatic zone economy could suffer different regions, dependent on exports of seafood.
Plus-one.ru was told that the climate crisis threatens the existence of 60% of the fish on the Ground and already is forcing some marine species to abandon habitats near the equator and migrate towards the poles. The warming of the water leads to an increase in acidity, causing the end of the century can disappear almost all coral reefs.
Canadian scientists believe that the Solomon Islands, Palau, cook Islands and other Pacific could lose 10-40% of the catch by mid-century. The economy of Oceania is largely dependent on fishing, and similar dynamics can seriously harm a region already suffering from rising water levels. Catch off the African coast could be reduced by 20% by 2050, which will reduce the number of jobs in the local fishery by 50%.
The experts urged the international community to prepare ourselves for the loss of catch and jobs. Because of the economy depend on the tropics and other regions, it is necessary to provide special support for these regions and enhance the overall combat greenhouse gas emissions, conclude the authors.
