Our Earth is facing some extreme climatic conditions nowadays. Everywhere people are talking about climate change and its impact on our environment. And a new study has revealed that a 6th mass extinction is underway and is set to worsen the world’s current “biodiversity crisis.”
The study informed that the common trends observed in the fossil record have the ability to inform and enunciate modern conservation efforts, given that the current biodiversity crisis is acknowledged as representing another mass extinction event. Previous mass extinctions have targeted newly evolving species which has severely limited the differentiation in animals. And scientists have warned that newly-evolving species of the current world are also being targeted to worsen biodiversity which could lead to sixth mass extinction.
Scientists studied the animals living between 260 million and 175 million years ago, and from them, almost 900 animals were from prior mass extinctions. Changes in animal differentiation were analyzed across Pangaea, a continent that stretched across all of Earth’s land masses. From the study, scientists found out, two mass extinctions took place in-between the targeted period and also many dinosaurs, mammals and turtles were formed in that period. Almost 252 million years ago, when Earth faced its largest extinction, around seventy percent of the land animals were targeted. Also, each extinction results in loss of many distinct features of animals that indicated that biodiversity levels hit incredible lows afterward. Hence, from these observations, researchers are trying to find out new conservative methods which could efficiently restore animal variability during the upcoming mass extinction.
The lead researcher in the study, David Button said that much like in history, the past provides cautionary tales and context for our ongoing future and the past informs us that the mass extinctions have bigger impacts beyond just species loss. Along with lack of biodiversity among animals, the current mass extinction is also being driven by a loss of habitat, pollution, and hunting. So, now humanity should step up conservation efforts to reduce the damage caused by the current extinction. Also, the research team added that the resulting biological annihilation obviously would have serious ecological, economic and social consequences and humanity is going to pay a heavy price for it. The study was published in the journal Nature Communications.
