Six years ago, Professor Stephen Hawking had a lesson to teach. He explained how "mankind is in danger of destroying ourselves by our greed and stupidity." And now, he's back to reassure we're still being very irresponsible when it comes to looking after the planet and ourselves.
In what is pretty perfect timing, the expert argued that pollution and human "stupidity" still remain the biggest threats to mankind in an interview on Larry King Now where he also discussed how a rebellion of rogue AI robots will evolve faster than humans.
The leading physician told the audience that "we have certainly not become less greedy or less stupid" when it comes to the environment, despite developments in research and eco-energy.
Here's exactly what the noble scientist said:
"Six years ago, I was warning about pollution and overcrowding, they have gotten worse since then. The population has grown by half a billion since our last interview, with no end in sight.
"At this rate, it will be eleven billion by 2100. Air pollution has increased by 8 percent over the past five years. More than 80 percent of inhabitants of urban areas are exposed to unsafe levels of air pollution.
"The increase in air pollution and the emission of increasing levels of carbon dioxide. Will we be too late to avoid dangerous levels of global warming?"
Are we really that stupid?
It doesn't really take a scientist to know that humans are predominantly to blame for the demise of the world. From mass shootings and unrelenting climate change to overpopulation and the breaking continents, we sure are headed for a dumbass ending to the planet as we know it.
Even if it is our stupid leaders we have to blame, it's not all lost if we continue the good fight towards a better world. While the smart professor has warned that we only have around 100 years to save the planet, that's quite a lot of time.
Hawking has said that to keep humanity safe during this time we must "recognise the dangers and control them," which is possible according to the self-described optimist.
He thinks as science continues to make advances in relative fields, we must also teach the population how it works. The 72-year-old scientist recommends "everyone needs to have a basic understanding of science to make informed decisions about the future," which could, in turn, save us. Let's get rid of stupidity then, yeah?
