Our rivers and oceans live since the 20th century a big problem that affects the survival of the species that inhabit them: overfishing. It happens when capturing a too high number of species that jeopardizes their ability to recover.
«In a single generation, human activity has seriously damaged the ocean catching fish faster than it can reproduce, while it destroys their feeding areas. Are needed changes to ensure an abundant marine life to future generations», said Marco Lambertini, director of WWF International»
The above fishing poses a great threat to marine biodiversity and ecological balance. The data are worrisome. According to the FAO, more than 80% of fish stocks for which data exist are exploited to the maximum. Another figure more than does Greenpeace: the abundance of populations of large predators such as tuna, cod and swordfish declined 90% because of overfishing. If we continue fishing at the current rate, scientists estimate that in 2048, it will be gone any fish in the sea.
This not only causes a big environmental problem also puts at risk the safety human food is declining alarmingly throughout the world.
A study by 2015 by the WWF ONG of marine mammals, birds, reptiles and fish shows that populations have been reduced, on average, halfway around the world over the past four decades, reaching some fish populations decrease 75%. The latest findings pose a problem for all Nations, especially for those who live in countries in the process of development, such as Colombia.
«Pressure is making unprecedented on our seas in Latin america. We extract from them more tuna, mackerel and sardines that is sustainable, affect complex ecosystems and marine landscapes as our mangroves and corals, and pollute their waters», said Roberto Troya, director of WWF Latin America and the Caribbean»
Our seas are vulnerable and sensitive and important and sudden number of specimens of a species change may exert great pressure on its ecological environment and a change in the balance of the oceans, and even in the food chain of other species. Illegal fishing or trawling depth are two major problems that increase the envelope exploitation of the marine world. In the latter case, talk about a technique of very destructive unsustainable fishing: large networks of these ships drag the ocean floor destroying and catching everything in its path. Of the captured between 30% and 60% corresponds to species that has been caught accidentally. Everything is pulled overboard.
Although the Nations are creating marine protected areas and are agreeing actions for the solution of this problem the truth is that these commitments are not sufficient to help the problem «the good news is that there are solutions and we know what that» make. The ocean is a renewable resource that can cater to future generations if we tackle these pressures effectively,»said Lambertini, director of the international NGO.
But is everyone’s responsibility to help as consumers, we can adopt measures of consumption to reduce overfishing. Organizations such as ecologists in action and ‘Without bad spine’ published the Guide of responsible consumption of fish and seafood to help consumers avoid products that are not properly tagged with or whose capture is associated with a greater environmental and social impact. For his part, Greenpeace calls on consumers that require supermarkets to develop a sustainable seafood purchasing policy and which do not consume fish species of its red list. The health of our oceans is at stake.
