In recent years, due to the despicable behaviors of some humans, many precious species on the earth are on the verge of extinction, but a piece of good news recently broke this deadlock. Today, from fish to Komodo dragon , International Union for Conservation of Nature has updated the list of the world's most endangered species. The Atlantic bluefin tuna school from the Mediterranean Sea near Sardinia, Italy has once again returned to its former vitality. These popular tuna species are no longer endangered. It is incredible that the species has recovered from overfishing.
It is understood that there are two bluefin tuna, one yellowfin tuna and one albacore tuna are no longer the main species, or are no longer critically endangered Deleted from the list of international endangered species. The unexpectedly rapid recovery indicates the success of efforts to end overfishing in the past decade, but tuna is not the only species discussed by scientists at the 2021 World Conservation Conference in Marseille, France, organized by the International Union for Conservation of Nature (IUCN) organization. For example, due to overfishing, habitat loss and climate change, more than one-third of the world's sharks and rays are still threatened with extinction. Scientists believe that sustainable fisheries are possible, and humans can eat fish in a sustainable way without reducing the number of fish to the point of extinction.
For most of the past 20 years, the World Conservation Union has evaluated the status of more than 60 species of tuna and . The research team announced the first comprehensive discovery in 2011, revealing that some commercially caught tuna species are at risk of extinction. Ten years later, tuna is no longer on the brink of extinction. This is comforting.
Currently, the World Conservation Union (IUCN) has included the world’s most endangered species on its red list of endangered species.And got the support of 16,000 experts worldwide. The alliance also announced that some animals are heading in another direction and entering the red list. A notable example is the Komodo dragon, a lizard that lives on the island and is particularly threatened by climate change.
According to new data, the Atlantic bluefin tuna, once classified as an endangered species, is now the least concerned species. The same is true for yellowfin tuna and albacore tuna, both of which were considered endangered at the time of the last assessment. In addition, southern bluefin tuna has improved from critically endangered to endangered status, while bigeye tuna will remain vulnerable.
Most people think that tuna is just a potential dinner, but these fish themselves are huge, incredible creatures. For example, when an Atlantic bluefin tuna begins its life, its eggs are not as thick as a credit card. But in ten years, it can grow to more than 6 feet long and weigh more than 550 pounds. Tuna are ferocious predators. They gallop through the ocean at speeds close to 40 miles per hour. They swallow their prey roundly—whatever they can.
Although these animals dwarf professional football players, they cannot match modern fishing techniques. Since the 1970s, longline fishing boats with bait hooks have been fishing the largest Atlantic bluefin tuna in the Gulf of Mexico every year. At the same time, seine caught smaller juvenile fish foraging on the east coast of North America.
However, reducing fishing quotas and enforcing these quotas helped their recovery. Not only that, tuna live in the vast oceans of the world and use different areas during their life cycle. This makes managing their populations quite complicated. Since the 1970s, the number of bluefin tuna in the western Atlantic Ocean has been severely reduced and has not yet fully recovered.
Hope of the Komodo Dragon
Another major development of the World Conservation Congress is to change the status of the Komodo dragon.But this transition is not as encouraging as tuna.
In the next 45 years, the inhabitants of the Indonesian Sunda Islands may see as much as 30% of their habitat affected by rising sea levels, which has prompted scientists to change the situation of this reptile from Fragile becomes endangered. Despite the imminent existential threat, the Komodo dragon may live better than other endangered species. The Indonesian government has pledged to save these dragons and officially launched a project in 2013, which includes cooperation between regional and local governments, as well as cooperation with local communities, academia, and non-governmental organizations.
Of course, the conservation work will never end, and we need to be vigilant to ensure that neither the tuna nor the Komodo dragon slip to the brink of extinction.
