INTRODUCTION

Thisessay is about the mistreatment of wild animals by humans.
For decades the animals have been cruelly abused, they have been married for caged to tame them and force them to perform stunts in the circus, in other cases to kill them and take out the skin and very powerful people or dealers of all these things.
The animals were disappearing as human accents were growing. So my work will talk abouthow was the life of the animals before, during and after humans populate the earth and become masters of it, and that due to this the animals were gradually disappearing with the ambition of certain people who only seek profit for themselves and do not realize that there are also around human beings who need and want to live in peace.
In biology and ecology, extinction is the end of an organismor of a group of organisms, normally species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena suchas Lazarus taxa, where a species presumed extinct abruptly "re-appears" after a period of apparent absence.
Through evolution, new species arise through the process of speciation where new varieties of organisms arise and thrive when they are able to find and exploit an ecological niche and species become extinct when they are no longer able to survive in changing conditions or against superiorcompetition. The relationship between animals and their ecological niches has been firmly established. Typical specie becomes extinct within 10 million years of its first appearance, although some species, called living fossils, survive virtually unchanged for hundreds of millions of years. Most extinction has occurred naturally, prior to Homo sapiens walking on Earth: it is estimated that 99.9% ofall species that have ever existed are now extinct.
In ecology, extinction is often used informally to refer to local extinction, in which specie ceases to exist in the chosen area of study, but it still exists elsewhere. This phenomenon is also known as extirpation. Local extinctions may be followed by a replacement of the species taken from other locations; wolf reintroduction is an example...
