What is biodiversity?

What Does biodiversity Mean

To begin to know the meaning of the term biodiversity, we are going to discover its etymological origin first. 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 the plurality of species of living beings that inhabit an environment. In its broadest sense, the concept refers to the variety of species existing on planet Earth .
Some two million species make up terrestrial biodiversity, which is the product of millions and millions of years of evolution developed according to the patterns of nature, but also of the influence exerted by human beings through their 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:

-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 make it up.

-The function, which is the set of evolutionary and ecological processes that occur. We are referring to issues such as pollination, nutrient cycling, competition, dispersal, parasitism ...
The concept of biodiversity was coined in the mid- 1980s , when the English expression biological diversity (translatable as “biological diversity” ) became biodiversity ( “biodiversity” ). Since then, and in the face of the growing negative influence of human action on the variety of species, the idea of ​​biodiversity has acquired more and more importance.
In addition to all 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. With this term we come to mention what are the different types of animals that exist in a specific territory.
Preserving biodiversity is essential to avoid the extinction of species. Each species that becomes extinct implies an imbalance in the ecosystem and less wealth on the planet. These imbalances can potentially be so great that they can even put life on earth at risk .
Biodiversity can be affected in multiple ways. The deforestation , a consequence of various industrial activities, makes many animals lose their habitat and they can not get food. Thus, little by little, the number of specimens is reduced and the extinction of the species may occur. The climate change , on the other hand, can also affect the survival of animals and plants.
