"I do not believe that homo sapiens is at risk of disappearing: we have always been able to get by even in the most critical situations. Indeed, often in the face of danger we have brought out the best in terms of creativity. I would say, let's not wait to rely on the technologies available to colonize other planets, because this step will take us a lot of time. In the meantime we should instead take care of the house that has hosted us so far and that as far as we know it is quite rare in our galactic neighborhood". This is what the evolutionist Telmo Pievani said about the future of human beings, who are threatened by many problems related to natural resources, climate change, overpopulation.
"The human species will evolve by taking the future in its own hands and not through the classical factors that have produced the evolution of species, hence the mutation, natural selection, ecological changes. And this will occur - Pievani explained - because homo sapiens today has become, as evolutionists say, a 'niche builder', that is, it has learned to deeply change the environment to make it suitable for his life and lifestyle". This role "is not only beautiful, interesting, a sign of progress, but also very dangerous: in this niche building activity, for example, we are dramatically impoverishing ecosystems". Piovani was talking about biodiversity, "which it has fallen by one third in all animal groups and in plants by now", and underlined that "climate change induced by human activities is another risk that we should really avoid". A change that he considers "a great evolutionary factor because it is modifying the regulation cycles of the Earth".
"Therefore we will face another step in our evolution: we will have to try to get by in an environment that is changing and will overreact to us. I believe that the best strategy will be to work a lot on scientific and technological research in order to find innovative and sustainable solutions to enhance human progress but tryinga at the same time to be less invasive and less destructive towards ecosystems. This is a big challenge in terms of foresight. We must teach homo sapiens to look a little farther into the future and be less short-sighted. This too should be an evolutionary, and indeed cognitive and urgent change to be implemented”, Pievani added.
