One of our more respected
and better regarded persons, David Attenborough, the naturalist, thinker and
broadcaster, in that order, took some heavy flak when he suggested that global population
growth at present rates was bad for the planet and for many other forms of life
therein.
It indicates that we are
at a stage at present when any attempt to look at population in terms of
demographics, economic history or statistics risks the wrath of the
racism lynch mobs and the ideologues determined to quash rational discussion.
So when there is an
election in which migration and movement have become questions and the
politicians are involved it all becomes very confused and emotional. Also, there are consequences.
One of the latest ones is
that it is suggested that we need to build 45,000 properties a year in London
to cope with expected inflows. This
would cater for about one to two hundred thousand people a year in that area
alone, perhaps a few more.
Once upon a time it is
claimed we humans existed by hunting and gathering alone. Whether it was some Garden of Eden or nasty,
brutish and short is one of the debates. However, if we look at The Atlantic
Isles alone what does this mean in terms of the numbers?
Again, we are in intricate
and argued areas of academic debate based on limited evidence. But if we take the thesis that an extended
family then needed around fifty square miles to sustain itself, this means
something like 2500 of them amounting, say, to between one and two hundred
thousand across the whole area, perhaps a few more.
As humanity grew in
numbers, clearly something would have to give and it did. We changed to cultivation of crops and
animals. This enabled a continuing and
rapid growth of numbers, curbed by periods of conflict, climate and weather
pattern variations, diseases, and shortages in foot or water supply or in forms
of energy needed to power systems.
If the academics who study
all these things are correct there have been many times in the past when either
locally or more generally events and happenings have impacted not simply on
population growth but size. With this
has been movement with its own consequences.
At the moment we have a
number of pots on the boil. In the USA
we are told that in California the San Andreas has been stuck in parts now for
too long and could glitch. There are
overheated volcano watchers secretly hoping for Yellowstone to blow with the
big one. Others think it is time for a
volcano series to bring about global cooling or a mini ice age.
There are those who watch
the seas and extreme weather. In the UK
at this moment there is a hurricane out there, Gonzalo, which could knock out
the power over large areas. And so on and so on, never mind long term energy,
water and other matters.
The key one is
food. The Atlantic Isles has to import a
great deal of it and does not hold large stocks. It depends on complex and highly organised
logistical systems for the mass of the population. We who go down to the farms are but a very
small minority.
Food has to be paid for,
as well as being transported. Food
prices can vary. As a lot of food supply
and provision is governed in the last analysis by financial speculators and
operators it is also dependent on sound credit and finance.
The more people and the
more they are concentrated into crowded urban areas the more we are all reliant
on the money systems as well as all the other facilities, few of which we have
much control over. And as we see time
and time again these are neither reliable nor certain.
We have the pre-conditions
in place for either problems or worse. If
it has happened before it can happen again and it has happened before very many
times and it is all down to the numbers.
But let's not talk about
it.
