A new global analysis confirmed that the world’s flora is becoming more and more uniform on all continents of the Earth, even in Australia. This is not good news, because scientists have been warning for decades that we are heading towards a new geological age, called “Homogecene.” Let’s see what this is about.
The term indicates when unique life forms (which can be found, perhaps, in certain places) are obscured by more adaptable species – most often invasive – that can live together with humans. Unfortunately, as ecologist Mark van Kleunen of the University of Constance in Germany says, “these effects are now evident even in the most remote corners of the world.”
It is a real destruction of the uniqueness of our ecosystems that should be countered. Obviously, even if I say so, this destruction is brought by human beings, who have reduced the distance between the “ecoregions” of the whole world. Even some scientists fear that the loss of natural barriers will one day create a “New Pangea” (seeing the topic, here is how the Pangea was divided).
This would be a place where there is no diversity, where vegetal and animal “super invaders” have “conquered” every corner and destroyed all the native creatures. In this regard, we recommend that you take a look at our special on the most dangerous invasive species. In the new study, experts examined the floral data from 658 regions around the world, including 189,762 species of flowering plants. Their results? It has been discovered that invasive plants have reduced the presence of unique species.
The ecological, evolutionary and socio-economic consequences of this change are unclear, but this is certainly not good news.
