$this->bbcode_second_pass_quote('Strummer', 'T')here's nothing fundamentally wrong about Malthus. The population still depends fully on agricultural production and that production still depends on the availability of fertile topsoil, constant input of energy and other resources (nitrates, phosphorus, etc...). In fact today it is much more dependent on those inputs than it was at any time in the past. The fact that we found some more temporarily available sources of those inputs than were known in Malthus' times does not change or invalidate his basic premise in any way.
No it doesn't but his specific prediction during his day that 18th century human population was critically over populated and at the tipping point was not true. For 200 years we are drawing down non renewable resource sinks. That is true. And we have avoided time and time again consequences.
Through sanitation, germ theory, green revolution in agriculture, digital technology, fossil fuels and last but not least, replacing natural ecosystems with human landscapes, all of this has allowed us to continue unabated since the time of Malthus to grow to 7.3 billion. To assume that this will all come to an end exactly during your or my lifetime is a potential fallacy of the doomer mind set.
This must be soberly acknowledged when attempting any kind of prediction going forward.
Will there be an end one day to this 200 year long linear exponential growth? Yes. Will it be through the catalyst of the consequences of human overshoot? Yes
Would I like to see the human foot print smaller on the planet? Yes
Would I embrace and welcome consequences that would return us to a sustainable population within carrying capacity? Yes
Copious Abundance states that carrying capacity is not definable and not exact and is influenced by too many factors. Like the ones I mentioned above; germ theory etc. While true there is a definition that serves me quite well. Homo sapiens can have whatever population it can afford to maintain as long as we have thriving and sustainable populations of natural ecosystems and bio regions, viable populations of
species with stable populations, allowing water sheds to keep viable populations of native wetlands, marine fisheries that allow for thriving populations of top predators like tuna. Etc etc. etc.
Maintaining resource sinks at renewable and sustainable levels like fresh water aquifers, top soil, etc.
Carbon emissions at a rate that it can be sequestered at a stable rate.
Anyone who wants to argue that carrying capacity can ignore any of those above mentioned examples is free to do so. And thus expose your hubris..... which is an invitation of sorts
