Global Biodiversity Falls Below Safe Levels

  • Global Biodiversity is being Lowered to a Dangerous Extent

The latest evidence shows that global biodiversity is being lowered to a dangerous extent thanks to the negative impact of pollution and global warming.

The loss of biodiversity may have reached a critical point of no return. Worldwide the ecosystems are under pressure. Not only are the animal and plant species caving in due to the SNAFU of climate change but human beings are also victims of their own clever machinations. With the destruction of so many habitats being a commonplace occurrence, the safety of the entire planet is at stake.  

The ecologists have every right to be worried. Biodiversity loss equals ecosystem dysfunction. Much of the subtle and minor changes that translate over time into huge mass shifts in species behavior are hardly understood by science.

We are literally playing with fire here. Thanks in no small part to our meddlesome ways, we have reached a standstill where only human beings can reverse the troubled conditions that are their own creation. 

“This is the first time we’ve quantified the effect of habitat loss on biodiversity globally in such detail and we’ve found that across most of the world biodiversity loss is no longer within the safe limit suggested by ecologists” explained lead researcher, Dr Tim Newbold from UCL.

“We know biodiversity loss affects ecosystem function but how it does this is not entirely clear. What we do know is that in many parts of the world, we are approaching a situation where human intervention might be needed to sustain ecosystem function.”

Grasslands, savannas and shrublands are the most affected by these changes. Many of the world’s forests and woodlands are going to the dogs thanks to the interventionist schemes of mankind. 

The function of biodiversity is to increase the growth of the variety of life forms in endless proliferation and lend support to nutrient recycling. Yet this is an uncertain and risky proposal at present.

Since everything is connected to everything else, the sort of plunder of Mother Nature that is taking place today will have very negative consequences in the near future.

If these trends are left unchecked, they will cast a shadow over the entire planet’s biosphere and lead to wholesale devastation and destruction. A sustainable future will become a thing of the past and everyone, rich or poor, will feel the pinch as everything from the food supply to the atmosphere gets degraded beyond recognition. 

“The greatest changes have happened in those places where most people live, which might affect physical and psychological wellbeing. To address this, we would have to preserve the remaining areas of natural vegetation and restore human-used lands,” said Dr Newbold.

More than half the globe is home to the human population. When biodiversity suffers, these human settlements too undergo various transformations that are a sign of the times.

The ecosystems start to dwindle as things go from a well-knit community to pure chaos. The way the land is used leads to these deleterious effects to manifest themselves.

Currently, we are entering the red zone as far as the safety of the planet is concerned. The decision is ours. Do we want to survive along with the rest of the animals and plants caught in the same ecological web as us? Or do we want the planet to end in a catastrophic species death that ultimately spells the doom of human beings too? The choice lies in our own hands.

This research is published today in the journal Science.
