About half of the Amazonian trees face extinction that is warned by international scientists. Amazon is the world largest rainforest that covers some parts of nine nations. It is about 7,000,000 sq kilometers. Among them Brazil itself covers the 60% of the rainforest. It is believed that the rainforest has been formed during the Eocene era and it appeared following a global reduction of tropical temperatures when the Atlantic ocean had widened sufficiently to provide a warm.
But the matter of worry that up to 57% of all Amazonian trees possibly fit the criteria of being globally threatened. And if it is happened the estimates would raise the number of threatened plant species on our earth and just in a quarter.
Among the threatened trees included some iconic trees like Brazil nut tree, food crops as for example cacao, which is the source of chocolate and also some other rare trees which are still unknown to scientists.
The research data that is published in Science Advances, experiment almost 1500 plots with the maps of present and predicted forest loss to calculate how many tree species have been lost and many are likely to exist by the middle of the century.
As Amazon is the world most diverse forest it could be the home of more than 15,000 tree species. Prof Carlos Peres, who is one of 158 researchers from 21 countries said that there was still a big gap in knowledge about all plants and animals in the Amazon.
He proclaimed that this research shows about half of all species may face extinction. He insists of proper management of parks and reserves that could decreased the extinction of threatened species. Another Prof William Laurance added that either we should stand up protect these critical parks and indigenous reserves of deforestation will erode then until we see large scale extinction.
It is noticeable that the IUCN Red List of Threatened Species is considered as the most comprehensive and objective global approach for evaluating the conservation status of plant and animal species.
