Feminine noun which is defined as the set of all species of living beings existing in the biosphere or the set of all species of living beings existing in a particular region or time. These are some of the definitions that our dictionaries give to the famous biodiversity, but where did this noun come from? Does it really deserve our attention? Why so much mobilization around this theme?

In order to answer these questions we need to understand what was happening in the world at that time. The "invention" of the word biodiversity is attributed to Walter G. Rosen in the mid-1980s while he was organizing an event on biological diversity in the United States, all when concerns about environmental issues began to take hold and several world scientists on the outside began to publish more frequently studies on species and their relations with the environment in which they lived, not long before that, in the 1970s, another word well known today was created, such as sustainability or sustainable development. The world began to look more closely at the problems that man himself was causing to nature and the ecological relations of species with the environment, we began to have an idea of ​​what we now call the Anthropocene (The idea that human actions are so drastic that we change the geology, landscape and evolution of the planet in such a way that we are living / creating a new geological age).

Every day new species are discovered all over the world, in a rhythm you can not imagine! Our planet is capable of sustaining so much life in so many different places that we humans, at the height of our intellectual arrogance, are not even close to knowing the amount of animals, plants, fungi and living things in general that exist on Earth. To put a little more drama in this, at the same pace as we discover new species we are also extinguishing species, many of which we do not even know, thanks to the frenetic pace that we open and destroy areas still untouched in nature, great example of this is our Amazon and tropical rainforest areas around the world, not to mention the accelerating speed that we have changed the physical and chemical properties of the seas and disturbed, probably irreversibly, the sustaining of life in the oceans. The prognosis is not at all encouraging!

But all is not lost, or at least there is still something to be saved. We are in a critical moment of human life on earth, and it is time to wake up to the consequences that our actions will bring to biodiversity on earth and for ourselves, after all by definition we are living beings that exist in the biosphere. As cliché as it may seem, our individual and routine actions are directly related to the great issues that guide the course we will take to the planet. Reducing the use of plastic, using less polluting transport, conscious consumption, recycling, organic products, alternative energy, certified products, dissemination of sustainable practices are some of the topics that we as individuals can practice in our daily life and in fact do difference as a society.

Let us not forget that we human beings, as animals and an integral part of the environment, can not avoid taking responsibility for our actions. It is our choices today that will put us in history as villains or heroes. Which side do you want to be on?
