The history of species extinction
It is the disappearance of all members of a species, this can be naturally, caused by man or by another more predominant species, extinction has occurred before the men inhabit the earth and this was given because of oxygen since from time to time oxygen is contaminated by various reasons thus causing the decrease in species or completely ending with them.
The reasons why the extinction of species occurs: due to the arrival of new species and this causes food scarce for both species and also causing the predominant species to feed on the others, another reason is the destruction of its Habitat for the activities of man This can be given by the logging of trees since people do so to be able to build their companies or find material to exploit, the burning of forests or grasslands as well as burning species and contaminating the environment Environment, as well as giving way to the first level of extinction that is the local, likewise global warming is another factor that affects the species since with high temperatures the poles melts thus causing the migration of animals such as polar bears, Penguins among others, with a percentage of 23% the last cause is hunting and extermination this occurs from the primitive era since man gave him different uses such as Pue If they are to feed with their meat and with their skin, cover up the high temperatures also used fangs as weapons, today hunting is still giving since some companies use the skin to make bags, shoes among other things.
Thanks to the collaboration of entities such as PETA or Swiss Animals Protection East/International that have managed to investigate and discover the atrocious way as they are maintained, beaten, electrocuted, hung and often snorted alive the poor animals that serve for the preparation of coats, hats , necks, sleeves and trim, today many people associate the use of skins with suffering and cruelty.
One of the main consequences that the extinction of the species brings is: the loss of genetic diversity since that can bring diseases since as we know some animals feed on insects and these are already contaminated with the fertilizers that the plants use like this Creating a chain of diseases, loss of biodiversity we know that both animals and plants form an ecosystem and this takes stock of the earth, this would affect the members of other existing species since they would not have a balance for their development. that would cause more lost species.
The extinction of species is based on three levels: the first is the local extinction this occurs when the members of this species no longer find themselves again in the place where it was located mainly but it can be found in another part of the world this can be Give for the arrival of new species, due to the lack of food among other things and this forces species to migrate to other places this is the current case of polar bears that have to migrate to another cold place. The second level is the ecological extension when the species are very few which make them not enough for reproduction this can be the case of the blue macaws, which just when they already believed it extinct a copy is born to save the species, the newspaper Grupo Formula says that “this bird, famous for inspiring the animated film ‘Río’, he believed himself extinct since 2000; This new copy will help its conservation ". (Contreras, 2019). The third level is the biological extinction this occurs when no member of the species on the earth is found again, being the case of the Java Tiger, since “its extinction occurred in the year of 1979 due to poaching to traffic With your skin, this together with the decrease in the dams to feed."
Around 99% of the species that have existed on Earth have been extinguished for different reasons, today the extinction continues to be more accelerated due to global warming this supported by man and this owes to pollution and involuntary burning Of ecological reserves, this is the case of the Brazilian Reserve.
On August 19, 2019, the sunset in Sao Paulo, the largest city in South America, was calculated for 5:51 p.m. But it was done at night two hours before. The explanation: a combination of a cold front, the fact that it is winter in the southern hemisphere and the smoke of forest fires in the Amazon basin, 2.500 km to the north.
After one species extinguits the probabilities that another new species arises is minimal, however there are species that adapt to these conditions as they did in pre -Hispanic ages, it is said that only the species that adapts this is adapts to this is the Case of the meganeura.
“An extinct genre of protodonate insects of the Meganeuridae family. Among its species is Meganeura Monyi, an insect of great resemblance to current dragonflies, with which it is related, which lived in the carboniferous period (300 mA) ”.
This also occurs when new natural resources can already be exploited and they stop surviving when a new threat arrives or are not able to survive new temperatures or other ecosystems.
Some species that help us subsist and that are in danger are the bees that, as we know, when pollinating the plants are giving us oxygen, however the human species has exploited it because it is one of the greatest producers of natural honey, as well as the fertilizers are one of the reasons why bees are losing specimens.
Another species that is in danger is the plant plankton this produces half of the oxygen we breathe and at the same time absorb carbon dioxide that exists on the surface and reduces the greenhouse effect thus maintaining a balance with climate change. "The seas and oceans are full of microorganisms that travel to drift and that are basic for life since they represent the base of the trophic pyramid of the planet".
Copy of extinct animals: zebra of the plains, gastric incubator, tiger of Tasmania, Bucardo, Imperial Carpenter Bird, Lanudo Rhinoceros, Foca Monje, Bilby, Black Rhinoceros Japanese Marine Leon, Dark Cost.
Copy of animals in danger of extinction: polar bear, tigers, kangaroos, red tuna, mountain gorilla, lute turtle, panda bears, penguins, Andalusian thorillo,
An example of animals that could return to life are bucces and gastric incubator frogs all this thanks to science, these animals are said to also help health.
On many occasions, selected animals can be useful in medication development. This is the case of the gastric incubator frog. It is proposed that it could help in the treatment of ulcers. This species is part of the Lázaro project, which seeks to relive several animals that have already disappeared. Bucardo is another example of animals that could be revived. Experiments have already been carried out to bring this species back to life. However, they have not been successful. (Five News, S.F.)
