The risk of the 6th great extinction on Earth

The world is facing a sixth major extinction, with 41% of amphibians being wiped out of the Earth's surface, according to a new study.

The researchers also claimed that more than a quarter of mammals and 13% of birds could end up tragically ending up as a lazy, extinct cuckoo from the late 17th century, because of human. Such a dark prospect could happen in 2200, if the creatures on Earth continue to disappear at the current rate.

Many creatures are now seriously threatened, including Magellanic penguins, Sumatra elephants and Amur leopard. However, more familiar animals may soon be added to this list.

These conjectures are given in an analysis conducted by Nature's scientific journal. The authors blamed the decline in habitat due to human activity as a key cause of this change.

"In general, biodiversity is deteriorating, in many cases extremely serious," said Derek Tittensor, marine ecologist at the Center for World Conservation Monitoring under the United Nations Environment Program. country, say.

Tittensor added that the destruction of habitats, pollution and overfishing has killed wildlife (including animals and plants) or made them extremely weak. According to the expert, the risk of further climate change will become more and more obvious and eventually kill the living creatures.

The Nature study highlights that gaps in scientific understanding of Earth's biodiversity are increasing the problem. For example, the study found that at least 993 insects are facing extinction, but so far, only 0.5% of nearly 1 million species have been studied.

Most of the endangered species are known to inhabit small areas of the world, often in habitats that are rapidly being destroyed. Conservation policies may slow down the process of extinction, but current trends imply, the rate of extinction will still be around 0.01-0.7% per year for all species. Friends

In July, a separate analysis published in Science magazine also discovered that a 6th great extinction was taking place. This report says, while previous great extinctions stemmed from the natural transformation of the planet or meteorite disaster attacks, the gradual death, the current wear and tear can be associated with human actions.

A recent study by Brown University (USA) also found that humans are causing species to disappear 1,000 times faster than they were 60 years ago.

5 great extinctions ever happened on Earth

The great extinction ended the Paleozoic

The first of five major extinctions ever recorded occurred on Earth about 440 million years ago. This may be the second most intense extinction in history. Nearly all life in the sea at that time and about 85% of species disappeared.

Great extinction at the end of the Devon century

About 359 - 375 million years ago, major environmental changes caused the elimination of key groups of fish on Earth and prevented new underground lakes from forming over 100 million years.

The great extinction ended Pecmi

The greatest mass extinction in history and the most serious impact on the Earth's ecosystem took place 252 million years ago. Almost 97% of species disappear forever and only fossils remain.

The great extinction ended in Triassic

Dinosaurs first appeared at the beginning of the Triassic period, but the large amphibians and mammalian reptiles are now terrestrial dominant creatures. The great extinction, which took place 201 million years ago, changed that.

The great extinction ended the Cretaceous

A meteorite has crashed into Earth 66 million years ago and is often considered to be the cause of ending the dinosaur dominance on our planet.
