The largest caribou in the world disappears almost half

The world's largest wild reindeer population living on Russia's Taimyr peninsula has decreased by 40% individuals due to climate change and human activity.

According to the BBC, information published at the Fall Meeting of the American Geophysical Association (AGU) took place December 12-16 in California, USA, following the latest warnings about the decline in numbers. some wild animals like giraffes, elephants, polar bears .

"The reindeer is extremely important for ecological diversity , " said Professor Andrey Petrov, director of the Northern Iowa University's Arctic Center, speaking at the conference. "They are a link in the Arctic food chain and without them, other species will be in danger."

Taimyr is home to the world's largest reindeer population. They have been closely monitored for nearly 50 years by aerial surveys and satellite imagery. The population has 1,000,000 individuals in 2000, but the latest research shows that the number of hours is only 600,000.

Researchers found that in the summer, reindeer swarms move north and reach higher lands. They argue that the reason for this phenomenon is because animals want to go to a cooler place as well as to avoid mosquitoes that proliferate in warm and humid places.

In addition, the industrial development process in the area also affects the habitat and distribution of reindeer populations when they have to travel further east to avoid humans. These changes increase the length of the journey that reindeer swarms must pass each migration.

"Now they have to take their newborns much further to reach their place of residence. That means the rate of caribou dead on the way increases," Professor Petrov explained. He also said that the rivers in the area are becoming larger in size, causing reindeer swarms to face many dangers when swimming instead of crossing the river.

Information about the decline in the number of individuals in the world's largest reindeer continues with the latest warnings about extinction of some wildlife species. Recent research by the International Conservation Union (IUCN) has shown that the number of giraffes globally has decreased by 40% over the past 30 years.

This number made giraffes first listed as "vulnerable" (vulnerable) in the Red Book. Statistics in the Red Book also show that about 24,307 out of a total of 85,604 species listed on the evaluation list in recent decades have stood on the brink of extinction.

Earlier, the International Wildlife Fund (WWF) predicted that by 2020, the earth would lose 67% of the animals, especially vertebrate species. Scientists warn that the 6th major extinction will occur if people do not take action to stop.
