The gases cause progressive acidification ending threatening breathing marine organisms.
To mark the celebration of Oceans Day Bio-geoscience the journal published a study that describes how the waters of the seas and oceans have absorbed about 25% of the CO2 emitted by man, which has led to chemical alteration.
The study, which was passed in a sector of the Humboldt Current along the Chilean coast, showed how high levels of carbon dioxide (CO2) and oxygen shortage compound the stress of marine life, which has brought a gradual acidification of the water, which constitutes a threat to calcifying organisms such as plankton and corals.
According to investigators, the respiration of marine organisms is being committed between 200 and 400 meters deep, which could have negative consequences for the fishing industry.
The World Oceans Day (June 8), designated in 1994 by the General Assembly of the United Nations has generated different reactions from organizations dedicated to preserving the environment. From Spain, responsible for marine protected areas of international environmental organization WWF, Oscar Esparza, again denounced the degradation of the oceans and count them as major threats overexploitation of marine resources, overfishing, destruction and fragmentation of marine habitats and marine pollution.
The Colombian case is no exception. The spokeswoman MarViva Colombia, María Margarita Gaitan, says the rise in sea level caused by climate change do not let it be a concern for the inhabitants of the coast , and from pollution of the oceans by the concentration of CO2 recalls which are those waters that humanity will give 80% of the air we breathe.
“The garbage in the water is another area of concern. The fishermen of Bahia Solano and tell us that the islands of garbage are increasingly closer to the coast, it is estimated that we are separated by 5 miles. Fishermen cast nets end up filling the bags and containers, food is at risk, “Gaitan said after mentioning that the oceans is estimated that annually receive 6.4 million tons of garbage.
The representative of MarViva adds that this threat to fishermen overfishing is added the large industries that advance in Colombian waters, “has become more technical as the harvesting of fish that vessels grades eventually sweep the entire population, leaving unsubstantiated artisanal fishermen. Tourists also come to our shores to eat our fish but it seems there will come a day when species such as tuna will no longer serve the table. “
From the International Environmental Fair which took place last Saturday in Bogotá, the organization called on the need for alternatives to preserve the life of the oceans through research projects, monitoring of industries that develop in the sea and the expansion of protected areas in artisanal fisheries.
