Biodiversity refers to the number of different living organisms that exist, and which are the product of evolution, those that have multiple ways of interacting, shaping life on the planet.
The human being is part of biodiversity, considered a natural heritage of the world and an element that provides balance to the biosphere.
An important characteristic of biodiversity is that it contains the different genetic information of each living being, each one of which is a functional element on which the maintenance of life on the planet depends, as well as the reservoir of the world's genetic potential, so it is necessary to guarantee its preservation.
