I see that Wikipedia has a more comprehensive page on Human
overpopulation, https://en.wikipedia.org/wiki/Human_overpopulation. I see
that it says that "Most contemporary estimates for the carrying capacity of
the Earth <https://en.wikipedia.org/wiki/Earth> under existing conditions
are between 4 billion and 16 billion. Depending on which estimate is used,
human overpopulation may or may not have already occurred. Nevertheless,
the rapid recent increase in human population is causing some concern."
Later in the article, it says "Many quantitative studies have estimated
the world's carrying capacity for humans, that is, a limit to the world
meta-analysis of 69 such studies suggests a point estimate of the limit to
be 7.7 billion people, while lower and upper meta-bounds for current
technology are estimated as 0.65 and 98 billion people, respectively".
Also, "The InterAcademy Panel Statement on Population Growth
1994, stated that many environmental problems, such as rising levels
carbon dioxide <https://en.wikipedia.org/wiki/Atmospheric_carbon_dioxide>,global
warming <https://en.wikipedia.org/wiki/Global_warming>, and pollution
<https://en.wikipedia.org/wiki/Pollution>, are aggravated by the population
<https://en.wikipedia.org/wiki/Human_overpopulation#cite_note-14>" I would
agree with "aggravated". And "However, many believe that waste and
especially by wealthy nations, is putting more strain on the environment
fits with the view that population multiplies the effects of consumption,
and vice versa, not that population, in and of itself, causes the problem.
What I think we do know is that large and fast growing populations
increase a wide variety of problems, the need to build more schools for
large numbers of children, find more water sources, build more electricity
capacity, roads, more food, more deforestation, overfishing, greenhouse gas
emissions, etc etc.
I recommend looking at the "Effects of human overpopulation" section
on the Human overpopulation webpage on Wikipedia, at the long list of
effects. It introduces them by saying "Some problems associated with or
exacerbated by human overpopulation and over-consumption are:"
Whatever the level of population that is not sustainable, if
population continues to grow, it will be exceeded sooner or later, since
resources are finite. I am reminded of the prediction of Malthus, that
population growth will exceed resources, and populations will be controlled
by starvation, war, or disease. In large part that has not happened since
his writings. The available resources have been greatly expanded by the
tool making revolution, the agricultural revolution (about 9000 years ago)
and the industrial revolution, and the green revolution (agriculture) (only
the last two were after Malthus). Whether that can continue over the
medium term or not is debatable, but in the very long term, it can't.
So agreed, population is at least one of the two ultimate causes of
coral reef degradation. But as I argued before, there is no way that
population can be reduced fast enough to save reefs.
I don't agree that we can't get off of our addition to fossil fuels.
Fossil fuels are heavily subsidized. In the US, oil companies receive $35
billion (with a "b") a year in direct subsidies. An excerpt from one of
Tom Goreau's recent papers says "At present the world subsidizes fossil
fuels to the rate of 500 billion dollars per year (Whitely, 2013), or about
$15 per tonne of CO2 emitted." Fossil burning plants do not have to pay
the societal costs of all the pollution they emit, if they did, they would
be uneconomical compared to renewable energy. Oil doesn't have to pay the
costs of the military necessary to keep the supply lines open in places
like the Persian Gulf. Remove the subsidies, and renewables would then be
cheaper than fossil fuel, and people will switch relatively quickly,
voluntarily. Yes, a huge change.
I agree that people in the developing world will be unwilling to
limit the growth of their economies. And I add that I don't think people
in developed countries have a right to demand that they do so, while people
in the developed countries consume so much more.
I agree we will have many drastic declines in many types of
ecosystems and quality of life long before CO2 levels become toxic (I don't
think anyone has proposed CO2 will reach toxic levels, asphyxiating people,
anytime in the near or even distant future).
I never said I was satisfied with incremental progress. I said I
would take what I can get. I'd much rather have rapid progress than slow,
and the slower we are, the more damage will be done before we get these
things under control. But I appreciate any ethical thing that helps us to
get farther towards our goal, and more quickly.
I don't think we have to choose between fixing the ultimate causes of
population and over-consumption on the one hand, and working on proximal
causes on the other hand. We can work on local causes of coral reef
decline and on reducing greenhouse gases, and on reducing population growth
rates and reducing consumption, all at once. In fact I think that's the
best way to go. As for the disease analogy, we have no cures for diseases
like colds or Ebola. We can only treat symptoms for those diseases, and
with colds at least, people recover on their own. Broadly speaking, human
populations increase in spite of diseases, and the human species survived
even before there was modern medicine to treat diseases. I don't think
that humans are necessarily doomed, nor is the environment. I do think
that overpopulation and over consumption, unless reduced, are likely to
greatly reduce the quality of life in the future for many.
Anyhow, we aren't going to save coral reefs by reducing population,
that will take at least a couple hundred years or more, the the big mass
mortality from bleaching is predicted to start in a few decades. (But if
anybody has a bright idea of how to reduce world population in just three
decades without killing vast numbers of people, please tell us.) The only
way to do it is to reduce local impacts, and reduce the emission of
greenhouse gases. All of which can be done in time to save reefs, without
waiting for population to be reduced. But it certainly won't be easy and
if we don't start making progress we're going to loose.

Hope from the Pope
Will Pope Francis's climate message break through where others have failed?
