To begin to know the meaning of the term biodiversity we will discover its etymological origin in the first place. This we can say that it is the result of the sum of two clearly differentiated words:
-The Greek noun "bios", which can be translated as "life".
-The Latin word "diversitas", which is synonymous with "variety".

It is called biodiversity to plurality of species of living beings They live in an environment. In its broadest sense, the concept refers to the variety of species on the planet. land .

About two million species they make up the terrestrial biodiversity, which is the product of millions and millions of years of an evolution developed according to the patterns of nature, but also of the influence exerted by the human being through his actions. This means that biodiversity does not depend exclusively on natural conditions, but that man, with his behavior, affects it.

When we talk about biodiversity, it should be noted that three fundamental aspects must be taken into account, such as the following:
-The structure, which is defined as the physical organization of each of the levels that shape it.
-The composition, which is the term used to refer to the variety of elements that comprise it.
-The function, which is the set of evolutionary and ecological processes that occur. We are referring to issues such as pollination, the nutrient cycle, competition, dispersion, parasitism ...

The concept of biodiversity was coined in the mid-decade of 1980 when the English expression biological diversity (translatable as "biological Diversity" ) became biodiversity ("Biodiversity" ). Since then, and before the growing negative influence of the action human on the variety of species, the idea of ​​biodiversity acquires more and more importance.

In addition to all of the above, we cannot ignore the existence of various types of biodiversity, such as the following:
-Genetic biodiversity. This refers to the fact that each species that exists on Earth is related to others through what are different genetic connections.
-Ecological biodiversity, which indicates not only the existence of numerous local species but also the dynamic interaction between them.
-Biodiversity of species. This term refers to what are the different types of animals that exist in a specific territory.

Preserving biodiversity is essential to prevent species extinction. Each species that goes extinct implies an imbalance in the ecosystem and a lower wealth of the planet. These imbalances can be potentially so great that they can even endanger terrestrial life .

Biodiversity can be affected in multiple ways. The deforestation , a consequence of various industrial activities, makes many animals They lose their habitat and cannot get food. Thus, little by little, the number of copies is reduced and the extinction of the species can occur. He climate change On the other hand, it can also affect the subsistence of animals and vegetables.
