World Endangered Species Day 2025: The functioning of humans in ecosystems has led to countless species disappearing or the danger of disappearing, which generates irreversible damage to biodiversity.
According to the United Nations, Of the 8,300 races of well -known animals, 8% are extinct and 22% threaten to die out. Some figures that have called the planet on the edge of what some scientists have called the Sixth big extinction.
Perhaps many could not imagine that their generation would witness from the start of the final disappearance of some animal and plant species of the earth. This tragedy can really be part of the person who wants to be Dying out number 6 that takes place on our planet.
According to a study by scientists from the Massachusetts Technology Institute (MIT)based on current carbon emissions, The next big extinction could take place within 80 years. This places it around the year 2100. What does it depend on? From the moment the ocean has absorbed 310,000 million tons of carbon.
World Endangered Species Day 2025
Donate May 20 He commemorated World Endangered Species DayAn ephemeris that takes place every third Monday of May and has been created to inform, warn and increase the threats of the world about an important part of living beings on the planet.
There World Endangered Species Day 2025 It is essential to know what we are talking about when we use this expression. In biology and ecology there has been “endangered species” applied to any species that runs the risk of disappearing in the short or medium term.
According to the World Congress of IUCN, three -quarters of endangered species are threatened for anthropogenic activities, led by agriculture, land conversion and over -exploitation of resources.
Definition and criteria
Today is the day World Endangered Species 2025 And the concepts with regard to this scourge must be very clear. A species is explained if it meets at least one of a series of precise criteria defined by the IUCN:
- Reduction of individual figures in at least 70 % in 10 years or 3 generations, if the causes of this reduction are known, reversible and stopped or at least 50 % if the causes are not safe, not reversible or still present.
- Professional surface less than 500 km², with population in descent, very fluctuating or fragmented.
- Population of less than 2500 adult individuals and in continuous descent.
- Population of less than 250 adult individuals.
- Probability of extinction of the species of at least 20% in the next 20 years or 5 generations.
What are these criteria for?
These criteria that have been established and validated by the International Union for the Conservation of Nature (IUCN) are specifying the risk of extinction of the species (current, short and medium term) and to allocate a state of preservation and, sometimes of protection.
There are 3 criteria for defined threats, which are collected in the IUCN -Red list. The species are classified in some of the following items.
The classification of small concern is performed with the only goal to have broader comparison parameters with which scientists and specialists can know the worldwide panorama of the state of the species. And NT implies that there is not enough data to classify the species (which does not mean that it cannot enjoy good health or be seriously threatened)
Why should we keep species?
In short, because the planet is a complicated and complex ecosystem that consists of millions of sub -ecosystems. And every being is vital to maintain the balance of the person who has to integrate so that your disappearance or the decrease in your amount can be fatal.
Man conquers new countries without stopping the new soils, getting rid and devoting to activities of their interest, such as agriculture or cattle. This causes conflicts as a result of proximity and increases the danger of zoonosis transfer, animals to people and vice versa. In addition to leaving millions of animals and plants without their natural habitat. Something to take into account a reflection date such as World Endangered Species Day 2025.
What species are in danger?
There World Endangered Species Day 2025 We must not forget that many iconic and charismatic species are located Danger of extinction. For example, Among the critical endangered species are three species of rhinos: the black rhino (Diceros Bicornis) in Africa and the Sumatra Rhinoos (Dicerorhinus Sumatrensis) and Java (Rhinoceros Sondaicus) in Asia, as well as the African forest elephant (Loxodonta Cichotis)).
In the endangered category we have the tiger (Panthera Tigris) and to the mountain gorilla (Gorilla Beringei). Among the emblematic species are classified as vulnerable the gigantic panda (Ailuropoda melanoleuca), The Giraffe (Giraffa Camelopardalis) and the Las Nieves Leopard (Panthera Uncia)).
