The word extinction (originating in Latin exstinctio) refers to the consequence or result of extinguishing or achieving extinction . For the biology and the ecology , the concept summarizes in a single term what happens when all the members of the same family disappear or species .
A genus, clan or species are considered extinct when their last member dies and, therefore, that group ceases to exist (since there are no chances of reproduction and it is impossible then to dream of a new generation). As the distribution of a species on this planet may become too broad, it is almost impossible to determine the exact moment of extinction.
Typically, species become extinct in the first decade of millions of years since their emergence. In some cases, however, they survive for millions of years. Some experts say that almost all of them are estimated to be 99.9%) that once populated the Earth are already extinct.
The increase in the human population and its greater geographical distribution have made extinctions become more frequent in the last 100,000 years. It is estimated that, by 2100, half of the species that currently exist could be extinct.
It should be noted that a classification has been developed that refers to the risk of extinction experienced by a species: the higher the risk, the greater the likelihood of extinction. A Threatened species It is one that could become extinct in the near future. A endangered specie , for its part, has its existence committed globally.
When the species is in critical danger of extinction , the risk is extremely high. The mountain gorilla, the Iberian lynx, the Mediterranean monk seal and the hawksbill turtle are some animals in this condition.
Voluntary Human Extinction
There is a movement called Movement for Voluntary Human Extinction which proposes the collaboration of all our species to release all the land, stop reproducing and getting that within hundreds of years the earth recovers its space, the rest of the animals decide how to live, evolve if they wish and the entire planet can recover from the damage caused by the human being.
It is not about exterminating our species by killing it, but about ceasing to procreate, never adding another human being to the population.
When talking about the human extinction people tend to be alarmed, however they do not do so much when it is about the disappearance of other species. Are we more important than them? When referring to extinction, we say that it is a natural process of life on Earth, so ... should ours also be one of the species that will cease to exist one day? What makes us think that it is not so? Just as we don't care about those that have already become extinct, we shouldn't do it for the human race. Most people who were once alive are dead and we all know that someday we will die. What is the difference between knowing that we will die and that our species ceases to exist?
Over the years the human being has allowed and has exterminated millions of species for a single cause, money, power, conquest; so species that for thousands of years they had known how to evolve transmitting their genetic codesThey disappeared overnight and no one fought to save them. The murder of life is one of the greatest crimes that the human being has committed that exists.
According to what this movement argues, which I ask you to think carefully, the extinction rate of our actuality is a thousand times higher than the average of all ages and could be solved in one way, with the extinction of ours because, apparently there is no reason to believe that this humanity changes.
In addition, it would be an excellent opportunity to show that we have not lost two of the qualities of our species that are most worthwhile: compassion and reason. The first, to understand what the planet needs and the second to act accordingly, make a decision and sustain it over time: suppressing the future life of our species to defend life That is already on this planet.
