A new theory designed by Swedish Scientists claims that humanity has exceeded 4 of the 9 limits for keeping the planet hospitable to modern life whilst according to another professor, the Earth may be seeing an impending human-made extinction of various species.
Environmental Science professor, executive director of the Stockholm Resilience Centre in Sweden, Johan Rockstrom, argues that there are 9 “planetary boundaries” in a new paper published in Science – and human beings have already crossed four of them.
Those 9 include carbon dioxide concentrations, maintaining biodiversity at 90 percent, the use of nitrogen and phosphorous, maintaining 75 percent of original forests, aerosol emissions, stratospheric ozone depletion, ocean acidification, fresh water use and the dumping of pollutants.
The planet has been our best friend by buffering our actions and showing its resilience. But for the first time ever, we might shift the planet from friend to foe,” says Rockstrom.
Just take a look at that!
On the other hand, Professor of Ethics Bron Taylor from the University of Florida said that we have accelerated the extinction crisis through deforestation and ocean acidification, a development which is driving species to extinction.
[Human] beings have increased, even from 1925, from 2 billion – which is considered to be a sustainable population for human beings, according to northern European consumption standards – to 7.2 billion at this point.”
What we have also done is increased the number of domestic animals, the ones we eat and the ones that are companion animals. We have 4.3 domestic animals one for every two human beings on the planet. Cultivating the land they need creates species extinction because where they are, other organism are not. Where we cut down forests for cattle, other species are not there. We are losing literally tens of thousands of endemic or native species to these trends.”
While Professor Taylor expresses anthropogenic extinction that are caused by human beings.
If you don’t have control over something, there is no moral obligation. In this case, we are doing it. So we have to ask the question: If we are doing something that is driving species off the planet, are we in some sense morally culpable?”
