Human activities have severely impacted global biodiversity: Study
A new study carried out to know the level of biodiversity on earth has found that around 58% of land on the planet has dropped below the biodiversity limits. The drop is mainly due to human land use practices and population growth which needs additional land.
Biodiversity as per study’s lead researcher Tim Newbold from the Centre for Biodiversity and Environment Research at University College London does not only impacts ecology, but also leads to changes in food production and personal well being.
The research findings have been based on Biodiversity Intactness Index (BII) that measures changes in species’ presence across the globe. Professor Newbold has assessed 39,100 species living in 18,600—locations across the globe.
From the assessment, the researchers have found that around 58% of earth’s land surface has dropped below 90% threshold. Even after considering the new species inclusion, the researchers have found that the biodiversity has dropped below 88%.
From the research, one point that is very clear is that biodiversity is very important to make sure ecosystem works smoothly in future. Out of the all the factors evaluated by the research team, grasslands using for grazing and crops have been the most affected. On the other hand, tundra regions have suffered the least.
Drop in biodiversity would not only impact natural world, but also prove costly. The researchers have also unveiled about the impacts that would be witnessed by a person on everyday basis. The researchers said that the two factors that could help in encouraging governments to come up with new policies are impact on the economy and impact on the individual.
Newbold said that efforts should be made to save the remaining natural habitat. “People should care, if not for biodiversity’s sake itself, because we know that biodiversity supports a lot of important functions, a lot of things we as humans rely on”, affirmed Newbold.
