Declination of biodiversity on the world’s ecosystem can be characterized by the influence of human activities. In fact, by human activities, the environment is deeply altered; territory has been modified totally, and some species are exploited directly by hunting, by biochemical cycle changing, and by transferring the species from one area to another of the planet. There are many other causes like loss and alternation of habitats, introduction of genetically-modified organisms, exotic species, pollution, and climatic changes.
