I 2016 was a difficult year for endangered animals, 2017 would be worse for species such as the vaquita, giraffes and cheetahs

2017 could be a difficult year for endangered species; This is due to the effects of climate change and the danger of a sixth mass extinction of the Earth, which World Wildlife Fund (WWF) warned in 2016.

In October 2016, WWF revealed in a report that between 1970 and 2016 there was a general 58% decrease in the number of fish, mammals, birds and reptiles around the world.

Which means that the fauna of the world vanishes at a rate of 2% a year.

There is a record of which species are threatened and endangered. This is the red list of the International Union for Conservation of Nature (IUCN), which has been classified for more than 50 years.

Far from shrinking, year after year this list grows. Although there have been species that have come out of the danger zone, an example is the panda, has also grown the number of people of animals that are added.

Currently there are more than five thousand species, simply in the section "in critical danger". In total, nine criteria are considered:

Extinguished
Extinct in the wild
Critically endangered
In danger
Vulnerable
Almost threatened
Minor concern
Insufficient data
Not rated

Endangered species for 2017

Bees

Seven species of yellow-faced bees entered the red list of endangered species in 2016. More than a quarter of the US bee population also has this problem.

This has severely devastating consequences for the world's food supply: bees are responsible for pollination of more than a third of the world's food.

Giraffes

Right in the center of the list are the giraffes. Its population declined 40% in 30 years.

The announcement was made just a few weeks ago, in Mexico. "While everyone cares about elephants, on Earth there are four times as many pachyderms as giraffes," said Julian Fannessy and Noelle Kumpel of IUCN

Cheetahs

Just days before the end of 2016, terrible news was announced about this feline: there are only seven thousand 100 wild animals left in the world; According to a study published in the scientific journal Proceedings of the National Academy of Sciences.

This report by the animal organization Panthera, specifically asks IUCN to categorize the cheetah as an endangered species.

African Gray Parrot

Also in December 2016, IUCN revealed that 11% of the species of this newly discovered bird is already in danger.

The African gray parrot was described as a "very intelligent" bird, able to imitate human speech. Its population has been reduced by 99% due to the loss of habitat and its capture.

Vaquita Marina

Phocoena sinus, better known as vaquita, is a critically endangered species. According to Greenpeace is the most threatened mammal in the world and lives only in Mexican waters, specifically, in the Upper Gulf of California.
