[Coral-List] Two news stories about coral reefs

Dear coral-listers,

as a follow up to Peter Sale's comments on how fast you can reduce human population, I'll share data from one branch of my family.

Country: Spain

Social context: From a fascist-nazi dictatorship where women had no rights, to democracy where women had access to education all the way to college and access to all birth control methods

Parent generation produced 10 children (6 of them survived to adulthood)

F1 generation produced 3 children

F2 generation has produced so far 0 children and projections show it will stay at 0 children.

Achieving negative population growth in only 3 generations. Just a tiny example on how valuing women as human beings, not as walking uterus and broodmares, and ensuring they have access to education, family planning and birth control, is the fastest way to achieve population control.

Hi Doug and listers,
Your recent post argues that it is per capita consumption of resources, rather than population size that best measures human impacts on ecosystems such as coral reefs.  You then state that in your view it is not productive "to complain about population causing reef declines, since there is nothing that is feasible or ethical that can be done about it soon enough to save the reefs" (my italics).  I have to differ.

First, while it is true that the impact of people on the planet depends on the size of our footprints, that is not a good reason to ignore population size entirely while complaining about per capita resource use.

Second, and this is why I decided to chime in, it is absolutely not true that it would take too long to reduce human population to make it a useful thing to advocate if one wants to save reefs, rainforests or any other ecosystem.  It is difficult to get unbiased discussion of China's population policy in English - most reports are either overt efforts to show how wrong it was to legislate fertility, or reports subtly influenced by such anti-China ideas.  But cutting through the anti-China bias, it is fact that China has wrestled its fertility rate from about 4.8 births per woman in 1975 down to 3.0 births per woman in 1980 when the policy was fully in place, and down to 1.5 to 1.6 births per woman in the years since 2000.  This is a very rapid reduction; it has brought China into line with most western European or North American countries very rapidly - we are all suffering the temporary pain of aging populations as population size falls (or is maintained by immigration from
 elsewhere).  By contrast, India is still dealing with a fertility rate of 2.5 births per woman.  Which of India or China would you prefer to govern right now?

You are correct that China's population has not yet fallen.  But in 20+ years, China stopped growing and is on the cusp of falling.  It seems likely that it will take at least another 35 years to wean the world off fossil fuels, and it is going to take most of this century to pull atmospheric CO2 down to levels needed to bring temperature below a 1.5 degree C increase from preindustrial.  That enormous challenge could be made easier if the giant fossil fuel corporations would join the fight to stop using their products, but it will also prove much easier if large parts of the developing world had stable or declining birth rates.  China's experience proves that shift in birth rate is attainable in a couple of decades.

There is value in pushing for serious efforts to reduce CO2 emissions.  There is value in pushing for local management efforts to keep ecosystems sustainable.  And there is value in pushing for 1) recognition of not just the desirability, but the need, for reduction of the global human population, and 2) real actions designed to achieve significant reduction over the next several decades.  Then we might be able to deliver flourishing coral reefs to future generations.
