Mott: "Those numbers are extremely conservative and probably far off the mark."
Jack: The Scientists came up with the number. They must have had a reason for the calculation.
Mott: "The planets human carrying capacity of the planet far exceeds the numbers the article quotes by 3 to 4 times those numbers."
Jack: Wow! Are you sure it's not 10 or 20 times the number the Article quotes? (I'm taking their word on this over yours)
Mott: "As for the ecological effects of course those areas seeing large population growth are profoundly impacted."
Jack: Yes. Scarcity of Fresh Water would be one thing.
Mott: "As to why more, that’s a question with no real answer."
Jack: The Answer would be LESS Humans. NOT MORE. Is there ANY benefit for MORE Humans on the Planet?
Mott: "Ultimately humanity is governed by the laws of biology and if human populations exceed the capacity to support life then large numbers of the excessive populations will die."
Jack: Yes. Or Humans have the capacity to see what could happen and Plan for the Future.
Mott: "... until a balance with carrying capacity is reached."
Jack: OR ... the Humans degrade the Planet, the Water, and the Atmosphere, to the point no Humans can exist on Earth, the Home Planet.
It's funny (not funny haha, but funny odd) that the same people that claim 'Climate Change' is caused by 'Human Activity', don't support a Program of Population Control.
Those numbers are extremely conservative and probably far off the mark. In North America alone only around 25% of our arable land is even populated. Approximately half the population of North America live in the Continental US east of the Mississippi River and even there the population density is about half that of Europe.
The planets human carrying capacity of the planet far exceeds the numbers the article quotes by 3 to 4 times those numbers. Look at Asia for another example. Of the 4.5 billion people in Asia 3 billion live in China and India with most of their populations concentrated along their coasts. Both nations together represent about 20% of the land area of Asia. Massive areas of northern and Central Asia are still sparsely populated but have the carrying capacity for much larger human populations. They may have unpleasant climates but certainly ones in which large numbers of humans can survive and thrive in.
As for the ecological effects of course those areas seeing large population growth are profoundly impacted. As to why more, that’s a question with no real answer. Because we can? Ultimately humanity is governed by the laws of biology and if human populations exceed the capacity to support life then large numbers of the excessive populations will die until a balance with carrying capacity is reached.
