Alert organization for protection of marine life

One of the highlights Komodo dragons, The world’s largest lizard, is considered a World Heritage Site. The classification of lizards has changed from “weak” to “threatening”.

Due to climate change, rising sea levels will reduce the ideal Komodo dragon habitat by at least 30% over the next 45 years.

The red list is also highlighted Marine species, Warning 37% sharks and rays Listed in the world as endangered. In addition, overfishing is often threatened Two of the five endangered sharks. Climate change is leading to loss of marine habitat and erosion.

On the other hand, the document redefined the seven most commercially tuna species, four of which applied more sustainable fishing quotas and gave indications of gratitude to countries that have successfully tackled illegal fishing. One is the yellowfin tuna, which has changed from “threatening” to “less anxious”.

A study published in the September 1 issue of the scientific journal “Nature” with the participation of Brazilian scientists revealed that fires in the Amazon since 2001 may have been affected. 95.5% of vertebrate and animal species have already been listed across biomes. Scientists used data from the IUCN.

According to Nature’s publication, man-made fires in the Amazon over the past 20 years have already affected 85.2% of endangered plant and animal habitats, and 53 of the 55 species of mammals have become extinct; 5 of the 9 endangered reptile species; Of the 107 amphibians, 95 are endangered; 236 of the 264 endangered plant species.

Among mammals that are endangered and directly affected by the Amazon fires, the study also cites examples of certain species of marmosets, spider monkeys, and some birds such as the Murchison.
