Is extinction of human life inevitable within several centuries?

Some of the changes that are already started have momentum and will require decades to susbside and stop if the causes of environmental degradation are removed.

There is a presumption that the sustainable population of the planet with environmental health is less than 3 billion. Population forecast for 2050 ranges from 9-11 billion. Currently 7+ billion.

Is it already too late?

Quote:

A Swedish scientist claims in a new theory that humanity has exceeded four of the nine limits for keeping the planet hospitable to modern life, while another professor told RT Earth may be seeing an impending human-made extinction of various species. Environmental science professor Johan Rockstrom, the executive director of the Stockholm Resilience Centre in Sweden, argues that there are nine “planetary boundaries” in a new paper published in Science – and human beings have already crossed four of them. Those nine 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,” said Rockstrom. “But for the first time ever, we might shift the planet from friend to foe.” Rockstrom’s planetary boundary theory was first conceived in 2007. His new paper reveals that because of climate stability, which began when the Ice Age ended 11,000 years ago, a planetary calm helped our ancestors to cultivate wheat, domesticate animals, and launch industrial and communications revolutions. But those advances have strained the stability of the planet, and Rockstrom says we have broken four boundaries: too much nitrogen has been added to ecosystems, too many forests have been cut down, the climate is changing too quickly and species are going extinct at too great a rate. Speaking to RT’s Ben Swann, 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,” he said.

Humans must cut down on their breeding.

We should be trying for a world where there are less than 500 million people in 100 years.

I know it will never happen.

Several centuries?

That is optimistic, imo.

Dear Longy,
nice to have you back after such a long ban.
Be good this time.

What do you think is the maximum sustainable carrying capacity of our planet?
( Some say 500 million people )

The oceans are dying because of carbon dioxide absorption and huge pollution loads that are forming islands of flotsam.

The presence of jetsam is not so evident but there are probably huge jetsam mounds under the sea which have not yet been studied.

Sea floor dead zones are increasing and expanding as pollutants poison the sea at river water and storm water outfalls. Many municpalities still discharge raw sewage into the sea. How many people remember the term Bondi Cigars for turds floating off Sydney beaches.

the term 'sustainable' is not defined. the the GREens, sustainable means not digging anything up, using energy or anything else that might make life easier.  Oddly, the predominantly gay greens, don't feel that being gay is NOT sustainable.

But there must be a point at which we only damage our environment & it can't recover.

Chopping down every tree is one example.

of course there is a breaking point, but we have never 'cut down every tree' or even gotten anywhere near it.

The greens have no problem with people using FREE sunlight energy although you have a problem with the idea that it is FREE don't you.

...when is longy going to set aside some of his precious time to answer that on behalf of the blue-blooded cracksmokers brigade?

tell me where I can get FREE solar panels + inverter and installation and then it will be truly free. but until then... it costs money - real money.

I wonder what God thinks, looking down on us running around like ants, fighting, fighting, fighting.

Then screwing over the planet's resources. Is this what he had in mind when he created us.

One day all the trees will be gone, all the seas rancid with filth and food practically non existent.

Then the repugnant human race, which wrecks everything it touches, will cease to exist.

At that point perhaps the planet might be able to recover perhaps over a million years or so.

The hubby often says, there are too many people, that is why there is so much unrest, so many cancers.
The more we populate, the more diseases we seem to create amongst ourselves.
Cancer for instance, isn't it now 1 in 3 or 2?
It seems if we are too many, we will cancel and cull ourselves out until it is more sustainable, in time.
The survival of the fittest etc.
The pollution humans put into the enviroment and waterways is vile, and we need to be more dilligent with changes, and get out of dirty living and embrace green living with all our mights.
Big money hungry companies/industries won't allow it to happen anytime soon, the change will happen, but it worries me, will it be too little too late?

And as for the extinction of other life forms (animals, fish, birds etc)....that is all our doing, killing for pleasure and profit.....why can't we just live and let live, and leave the other life forms be? What is it with humans having to kill?
So many that care try to rectify it (the poaching etc), and get killed themselves for being the good guys  :-[ All for the love and greed of money.

Yeah well tank water is currently free except for the price of the tank..... yet they are looking at ways fo charging people for that collection just like they do to farmers who have dug dams on their properties.

Like rats in a cage. When it's overcrowded they fight.  Although much of the world claims to be living in a democracy and most people recognise that over population is one of the main causes of our problems, esp environmental damage, the rulers of the world are insisting that the world can fit more.  Why you ask? Because the fastest way to exploit the worlds resources is to have as many people working it as possible.

If we don't twig soon that representatives claiming to work for our interests will always (and I mean ALWAYS) betray us, perhaps we deserve to get screwed over.

We already have peak child at around 2 billion.
The human population is on track to peak at 11 billion then start decreasing.

Best angle is to increase education so to bring everyone into the developed world and have more educated people working on solutions.

We're not quite 7 billion now. The oceans are quickly getting fished out and turning into a cesspool; arable land is dwindling due to urban sprawl, overuse, over fertilization and contamination and the rivers and the aquifers are drying up and you think we should wait till we add another 5 billion people before putting in a concerted effort to slow the breeding down. God I hate political parties!!!

Welcome.. to Planet Hospitality!

You may not realise it yet, but you've just arrived via the sphincter of a worm hole at THE most desired destination in the Universe.

IMHO I think that after the next Ice Age, which some think is always preceded by a short warming period, but after the next Ice Age I predict Mother Nature will have cleansed the earth of all infestations (us being but one) to a point that if any ferals survive the Ice Age itself, they will have to evolve from step one all over again. I also believe that this has all happened many times before in Earth's 4+ Billion years of existence.

In the end history will continually repeat, until the sun itself fails to shine. Then, & only then, will mankind really be in deep poopie doopie.

So, everyone live for today, & to hell with tomorrow because were all going to die someday anyway. Mother Nature has never needed our help before, & she doesnt need or want it now.

Within 500 million years the Earth will be too hot for life.

The sun & all other stars like it get minutely hotter every year.
