It is the law of the universe. What goes up must come down. And it’s 
not whether we are coming down, but how fast we will come down that is 
the issue.  
We
 seem stuck on economic growth, but it is not a wholesome growth, it is a
 growth that undermines itself.  The ecological economist Herman Daly 
asks:  “ When the economy is growing, what is it that is getting 
bigger?”.  
“Throughput
 is the relevant magnitude for answering the question of how big the 
economy is” , Daly says.    It’s “the metabolic flow of useful matter 
and energy from environmental sources, through the economic subsystem 
and back to the environmental sinks as a waste. “  
Most
 economists picture the human economy in a separate box somewhere, 
existing independently of nature.  It’s a way of simplifying the initial
 assumptions in order to build a model of human behaviour .  This assumption works  well for deriving supply and demand curves but there is a problem 
with these assumptions when the concept of economic growth is introduced. 
 With growth, our assumption of the economy being independent of nature 
leads to disastrous results.  
Why
 is this idea of throughput relevant? Because the earth and the living 
system that exists on it is finite. There is a finite amount of energy 
and materials available to the  web of life that supports us. 
 The human economy is a part of the earth’s Eco-systems but the economy
 is growing big enough to threaten the entire web of life.  A major 
extinction event, like the one that finished off the dinosaurs 65 
million years ago,  the kind that has happened about every 100 million 
years in Earth’s history, is happening right now.  And it’s human 
economic growth that is fueling it.  We are burning up our future 
inheritance in a giant flare of fossil fuels.
 If the economy is growing what is growing?  Throughput.   Through-put 
is taking things from nature, then processing them and consuming them and 
sending the remains back into nature in a degraded state. The best illustration
 I have seen of this idea is  an entertaining two minute  youtube 
video called “The Impossible Hamster.”   
If
 we live on a world, that world has bounds.  We cannot escape those 
bounds. However,  we could extend out our future on Earth if we stopped economic growth.
 In his new book Prosperity Without Growth, British Economist Tim 
Jackson, explains what’s involved in stopping growth, why it’s 
controversial, and sketches how we would go about doing it.
 One of Jackson’s arguments is that  The focus  of the present system on
 continually increasing the efficiency of  labour is  wrong when the 
result is increasing inequality,  job loss, and declining communities. .
  A job is a fundamental part of a meaningful life.  Every community 
works better when there is less unemployment.  Jackson suggests that 
job-sharing and worker owned enterprises be expanded.  
This
 is a similar position that local, Vancouver author Conrad Schmidt also 
emphasizes in his book “Efficiency Shifting”. What economic efficiency 
usually means is needing less people to do the same thing.  So if 
agriculture becomes more efficient, then we get a lot of unemployed 
agricultural workers.  
Schmidt
 recognizes that we cannot keep growing the economy in order to reduce 
this  unemployment.  He argues that we can avoid  both growth and 
unemployment if we  let certain economic sectors such as education, 
healthcare, and agriculture become more inefficient by employing more 
labour.  Too much efficiency in education and healthcare leads to 
inferior quality and less caring. These are activities that benefit from
 people taking more time rather than less time to do the job right.  
Schmidt
 devotes a separate chapter to agriculture.  In it, he argues that a 
policy of encouraging organic farming would be better for farmers in 
less developed nations because it wouldn’t flood global markets with 
cheap food, as does present U.S. policy of encouraging industrial 
farming. Plus organic farming  employs more labour and uses less 
pesticides, and encourages less meat production than industrial farming.
Economic
 efficiency is not as important as the fulfilment of human potential. 
  People ought to be productively employed, jobs ought to be fulfilling 
and rewarding.  Economic incentives ought to be turned around to support
 investment in social capital, natural capital, and in strengthening the
  public sector.   People’s worth and dignity need to always be 
respected over the demands of the market.  
As
 the authors of Economics Unmasked say:  Economy for the people, not 
people for the economy. Profits and prices need to be driving 
sustainability not the degradation of humanity and nature.
  As Tim Jackson argues, the financial sector needs to change into the 
Eco-economic sector:  the overall incentive structure should encourage 
investments in renewable energy and in increasing resource efficiencies,
 and discourage the underemployment of human resources. 
There
 needs to be a massive shift from consumption to savings.  And a new 
incentive structure in place to encourage investment in public 
enterprises like mass transit, railways, universal education,  and in 
the conservation of Eco-systems for they form the basic support for our 
economies.If we invested in Eco-system health and maintenance we would 
be ensuring our survival and the stability of our civilization.  
Because
 the earth’s climate has gotten warmer we know we’ve reached a limit. 
 We need to stop the growth of throughput, if we are to save the earth’s
 biological systems from degrading.      Better to take a slow descent 
by putting on the brakes now, then overshooting the peak and running off
 a cliff.  Planning for the worst and making ourselves more resilient, 
more able to survive and adapt to shocks to the system  is the most 
prudent option.
  
 It’s not because it’s not possible, it’s because of the way we define 
economic variables and the way we’ve structured the system that it seems
 so difficult to see our way out of it.  Let’s redefine economics so 
that the economy is recognized as a part of the Earth’s biosphere.  This
 alone would lead to fundamental changes.  
The
 other big point of leverage is fossil fuel use.  Fossil fuels are 
exactly what has allowed our economies to  grow and they have done this 
by fueling the rapid acceleration of throughput.  This acceleration is 
at the heart of what is causing global warming and mass extinctions.  
One
 of the least difficult, but most significant things we could do to change this destructive spiral is to 
accompany our children to school, either by walking or by cycling, rather than driving them.   And 
if that is not physically possible consider moving to a community where 
it is safe to walk or cycle to school.   It is an opportunity to let our children  be more active and 
self-sufficient.  The results will be healthier adults and a healthier 
society.  
 Our dependence on fossil fuels is a terrible trap that is slowly 
choking the life out of this planet. There should be massive 
dis-incentives to fossil-fuel use.  A carbon tax, should be put on all 
fossil fuels at the well-head or in the coal mine.  All subsidies to the
 fossil fuel industries should be eliminated.  It is, after all, the 
richest industry on the planet and can survive very well without 
subsidies. 
 There are many unacknowledged costs to economic growth and fossil fuel use. For example, 
destruction of clean water by fossil fuel extraction and processing.  The greater risks of cancer from being downstream of tar sands oil 
extraction or nuclear plant disasters.   The increase in respiratory 
ailments due to particulate matter and toxic byproduct from burning 
fossil fuels.  The loss of our physical health from our overuse of motor
 vehicles and subsequent  lack of exercise.  Our loss of mental health 
and the destruction of once viable communities  due to the  Increasing 
isolation and excessive individualism of consumer, suburban, automobile 
culture. I’m only highlighting a few of the costs. And others could list
 many more. 
  
Unfortunately
 our political and ideological systems are fixated on seeing economic 
growth as the only way forward.  This almost religious tendency -  to see 
growth as our salvation, is having the bizarre consequence of leading 
our political and economic elite to embed themselves with the fossil 
fuel industry.
It’s
 a big mistake to leave economic planning up to our political leaders. 
   We should All participate in planning a new economic system.
