Who to believe???? Some experts insist on telling us that our Earth won't be able to sustain the exploding population. On the other hand, other experts like the Canadian guys in the vid below have data that seem to show that our population growth has begun to shrink.
Whatever ... quite an interesting vid.

Looking at the "day the dinosaurs died" with a fresh new perspective
This is a fascinating article and I highly recommend you read it in its entirety.
Douglas Preston at TheNewYorker.com
The Day the Dinosaurs Died
"A young paleontologist may have discovered a record of the most significant event in the history of life on Earth."
If, on a certain evening about sixty-six million years ago, you had stood somewhere in North America and looked up at the sky, you would have soon made out what appeared to be a star. If you watched for an hour or two, the star would have seemed to grow in brightness, although it barely moved. That’s because it was not a star but an asteroid, and it was headed directly for Earth at about forty-five thousand miles an hour. Sixty hours later, the asteroid hit. The air in front was compressed and violently heated, and it blasted a hole through the atmosphere, generating a supersonic shock wave. The asteroid struck a shallow sea where the Yucatán peninsula is today. In that moment, the Cretaceous period ended and the Paleogene period began.....
......Some of the ejecta escaped Earth’s gravitational pull and went into irregular orbits around the sun. Over millions of years, bits of it found their way to other planets and moons in the solar system. Mars was eventually strewn with the debris—just as pieces of Mars, knocked aloft by ancient asteroid impacts, have been found on Earth. A 2013 study in the journal Astrobiology estimated that tens of thousands of pounds of impact rubble may have landed on Titan, a moon of Saturn, and on Europa and Callisto, which orbit Jupiter—three satellites that scientists believe may have promising habitats for life. Mathematical models indicate that at least some of this vagabond debris still harbored living microbes. The asteroid may have sown life throughout the solar system, even as it ravaged life on Earth......
....Earth itself became toxic. When the asteroid struck, it vaporized layers of limestone, releasing into the atmosphere a trillion tons of carbon dioxide, ten billion tons of methane, and a billion tons of carbon monoxide; all three are powerful greenhouse gases. The impact also vaporized anhydrite rock, which blasted ten trillion tons of sulfur compounds aloft. The sulfur combined with water to form sulfuric acid, which then fell as an acid rain that may have been potent enough to strip the leaves from any surviving plants and to leach the nutrients from the soil.
Today, the layer of debris, ash, and soot deposited by the asteroid strike is preserved in the Earth’s sediment as a stripe of black about the thickness of a notebook. This is called the KT boundary, because it marks the dividing line between the Cretaceous period and the Tertiary period. (The Tertiary has been redefined as the Paleogene, but the term “KT” persists.) Mysteries abound above and below the KT layer. In the late Cretaceous, widespread volcanoes spewed vast quantities of gas and dust into the atmosphere, and the air contained far higher levels of carbon dioxide than the air that we breathe now. The climate was tropical, and the planet was perhaps entirely free of...........

Global Warming explained .....
in a way that might get some of us non-believers look at the issue with new eyes.
Paul Craig Roberts at his blog
Is The Evidence of Global Warming Too Scary For Humans To Cope With?
I appreciate the numerous emails thanking me for providing an understandable explanation of the global warming scenario. The book, Unprecedented Crime, about which I reported, caused me to start thinking more seriously about man-made global warming. I already was thinking about it, because capitalism owes its profits to the costs that it imposes on the environment, costs that are external to the capitalist entity. I have been thinking about this since I addressed “external costs” in my 2013 book, The Failure of Laissez Faire Capitalism. I am thinking that if man-made global warming is indeed in the cards, as the current evidence supports, the external costs of capitalism will far exceed the total value of all the goods produced over the course of the industrial revolution. Past material comforts will be paid for by future curtailment of life on Earth. Greed, gluttony, envy, lust, and pride will have proven to be the five of the seven deadly sins that were deadly for planet Earth.
I hope I can find the time and energy to get around to a book on the subject. For now, like you, I am learning. It struck me, as it strikes many of you, how a one or two degree rise in temperature can cause ice caps, glaciers, and the Greenland ice shelf to melt. We don’t think of the Arctic or glaciers hovering on the temperature border of frozen and melting. It is not intuitive that small changes can make such large differences.
Like you, I also found it puzzling that as carbon dioxide is only a small part of the atmosphere, how its increase can have such dangerous effects.
While struggling to put what I learned into understandable language, I thankfully came across this explanation in Scientific American:
“Small changes in the Earth’s heat balance can lead to large climatic changes. For example, the ice ages during the last several million years–and the warmer periods in between–appear to have been triggered by no more than a different seasonal and latitudinal distribution of the solar energy absorbed by the Earth, not by a change in output from the sun. The geologic record shows that the differences in ice cover, sea level and precipitation as well as in plant and animal populations were quite dramatic between the ice ages and the warm interglacials. Yet the global average temperature differences corresponding to these radically different climates were only about 5 degrees C in the tropics and 8 degrees C in polar regions.”
In case you don’t understand what is being said, the message is that very small differences in temperature are the difference between ice ages and heat extinction ages.
Scientific American asks this question—“If carbon dioxide makes up only a minute portion of the atmosphere, how can global warming be traced to it? And how can such a tiny amount of change produce such large effects?”—and Pieter Tans, a senior scientist at the National Oceanic and Atmospheric Administration (NOAA) Earth System Research Laboratory, provides this answer: https://www.scientificamerican.com/article/if-carbon-dioxide-makes-u/ Read it, and you will understand...….

The Climate Change fear-mongering continues to continue
Two items below to try and make you change your mind about the climate change fear-mongering.
Don't let the PTB manipulate you into the climate change hoax to squeeze more taxes out of individuals like Joe and Jane, Tom and Mary... ordinary people like us. The carbon tax will be affecting only the public not the corporations ruling over the politicians and giving directives to them to be passed on to little us. Bankers and billionaires are salivating at the thought of all the loot "carbon tax" money they will be able to grab once the carbon tax levies are introduced. If you think this would be something only the polluters will have to be wary of, you are sadly mistaken. The refineries, oil corporations, the rich as usual will get away paying nothing, you on the other hand will be paying what you should not be penalized with but will be. MOREOVER, our Earth has gone through such changes again and again and again and again. It's not the end of the world as the PTB want us to think.
And, just a bit of the article from F William Engdahl at Journal Neo

The Dark Story Behind Global Warming aka Climate Change
.....The most interesting about the dire
warnings of global catastrophe if dramatic changes to our living
standards are not undertaken urgently, is that the dire warnings are
always attempts to frighten based on future prediction. When the
“tipping point” of so-called irreversibility is passed with no evident
catastrophe, they invent a new future point.
In 1982 Mostafa Tolba, executive
director of the UN Environment Program (UNEP), warned the “world faces
an ecological disaster as final as nuclear war within a couple of
decades unless governments act now.” He predicted lack of action would
bring “by the turn of the century, an environmental catastrophe which
will witness devastation as complete, as irreversible as any nuclear
holocaust.”In 1989 Noel Brown, of the UN Environmental Program (UNEP),
said entire nations could be wiped off the face of the earth by rising
sea levels if the global warming trend is not reversed by the year 2000.
James Hansen, a key figure in the doomsday scenarios declared at that
time that 350 ppm of CO2 was the upper limit, “to preserve a planet
similar to that on which civilization developed and to which life on
Earth is adapted.” Rajendra Pachauri, then the chief of the UN IPPC,
declared that 2012 was the climate deadline by which it was imperative
to act: “If there’s no action before 2012, that’s too late.” Today the measured level is 414.
As UK scientist Philip Stott notes, “In
essence, the Earth has been given a 10-year survival warning regularly
for the last fifty or so years. …Our post-modern period of climate
change angst can probably be traced back to the late-1960s…By 1973, and
the ‘global cooling’ scare, it was in full swing, with predictions of
the imminent collapse of the world within ten to twenty
years…Environmentalists were warning that, by the year 2000, the
population of the US would have fallen to only 22 million. In 1987, the
scare abruptly changed to ‘global warming’, and the IPCC (the
Intergovernmental Panel on Climate Change) was established (1988)…”
