We need a revolution.
I don’t mean a dirty bloody revolution that
loses lives. Our culture has risen
beyond that kind of extreme correction.
But extreme correction we desperately need.
The issue is the elephant in the room, the
issue that no politician wants to address.
The issue is our addiction to our current life style.
If we continue to do what we are doing, we
are going to destroy this planet. I dont
understand how that is not clear to any sane thinking person.
Over the last two hundred years we have
burnt the accumulated deposits of many millions of years. Those carbon deposits have produced carbon
dioxide in the atmosphere. The burning
of those deposits has resulted in an increase in the concentration of CO2 from
around 250 ppm to somewhere now near 400 ppm, way in excess of the 350 ppm that
we had thought was a reasonable upper limit.
The effect of that increase is the warming
of the atmosphere. That warming has
reached the point where we are losing or have lost, very significant amounts of
the accumulated ice in both northern and southern hemispheres. The seas are rising, and temperatures
throughout the world are rising.
The rate at which these things are
happening may be up for debate, but the fact that they are happening is not. We are heading for a climate change like no
other the human species has experienced, nor indeed, any other life form on
this planet.
We are also facing, independent of the
climate change, a rapid exhaustion of the resources we need to survive. It is quite absurd how our leaders spend
their time during election campaigns, claiming that continued, sustainable,
growth is the only answer to our problems.
When in fact it is continued growth that is unsustainable, and the cause
of our problems, not the solution.
Continued growth if “sustained” at any
annual rate of change will result in the end of our civilisation. The simple binomial theorem spells this
out. All politicians and advisers should
be taught this simple theorem.
When a quantity grows exponentially, it can
be shown that there is a doubling time, that is to say the time in which the
quantity will double in size. Whether
the growth is one per cent or 100 per cent, there will always be a doubling
time. If growth is sustained, then
inevitably the quantity will double. In
an additional doubling time, the quantity will double again, then four times
its original size, and so on.
The doubling time can be calculated very
trivially as 70 divided by the rate of growth.
If the rate of growth is 1 per cent, then the quantity will double in 70
years; if the rate of growth is 7 per cent, it will double in 10 years. Only if there is a zero percent growth, or a
negative growth, can the expansion halt or even be reduced.
The problem with the doubling is this: If we expect the economy to grow at say 2
percent a year, often thought to be a good idea, then everything associated
with the economy can be expected to grow similarly. Population will grow at that rate; houses
built will grow at that rate; roads will be surfaced at that rate; demand for
food will grow at that rate; demand for cars will grow and demand for fuel will
grow at the same rate, if not faster; garbage production and waste will
similarly grow.
In particular land occupation will
grow. Once land has been occupied, it is
rarely if ever returned to its natural state.
Suppose for example, that 5% of our
available land is currently occupied by human development. If our economy is growing at 2%, then in 35
years, 10% of our land will be occupied, in another 35 years (ie 70 years from
now), 20% will be occupied, in another70 years we will have occupied 80%, and
have none left for adoption within the next doubling time, 150 years in the
future.
We may not be growing at 2%, but the point
is that any growth will ultimately result in the occupation of all our land,
vast as it appears to be today.
And at what cost? The land that vanishes under the hammer is
often the best agricultural land, often because agricultural land is
under-valued. We will have lost
substantial amounts of the soil we need to live on. If we have to depend on imported foodstuffs,
what then?
Well, of course our habits have been
exported. Already vast amounts of the
arable land of the rest of the world, the areas we currently depend on for food
(and enjoyment) are vanishing under the same development pressures we have created
at home. So unless we have the capacity
at home, we will within the lifetimes of our grandchildren’s children, not be
able to eat. We cannot depend on the
rest of the world.
The thing that should drive the point home
is the staggering cost of our daily commute.
Whether you are stuck (in Canada) on the Gardiner, the 401, The Don
Valley, the Queensway, the 50 or the 2 and 20, you know that you are wasting
fuel.
With a quick calculation, the production of
CO2 in our traffic jams, in our daily commute is one third of the daily
contribution to global warming. If you
travel 20 kilometres each way, or 12,000 a year, you will use some 2,500 pounds
of gasoline, and produce some 6,000 pounds of CO2. With each of 200 million North American
commuters doing the same thing, we collectively will have added some 600
megatons CO2 to the atmosphere, about a third of the 1.7 gigatons we add each
year.
Of course, the CEOs of Exxon and Shell et
al are laughing their ways to the bank!
And funding the ever growing disaster of fracking and heavy tar sands
extraction.
Yet, unless we change our habits, we will
get where we are going. Unless we find
ways of not consuming, of not commuting at inordinate cost, we will not have an
environment in which we can live.
Unless we change our living styles, we will
exhaust this planet. Without a planet we
have nowhere to live.
We need a revolution immediately. If not sooner!
