After just having written about learning to learn again, I thought I might just post something about what I have learned, and what better than the conclusion, in summary, of the course? I have now spent 8 weeks looking at
various aspects of sustainability, population, climate change, our
use of the commons, policy etc. And as in the beginning of the course,
the one big question is still: Is the world on an unsustainable path?
How has the course changed my view? Not
much, I must say. I started out thinking that the main problem with
managing our planet sustainably is human behaviour. We have the
technology to solve most problems, we know a lot about the science
behind natural processes and how to utilise them sustainably, but
where we struggle is human behaviour, how we treat our world. Policy
is a powerful tool that could help on the way to change our
behaviour, and to some extent it does, we have seen several examples
of Pigovian taxes or incentive-based policies that have helped bring
about an improvement in for example air quality and water pollution
remediation in most developed countries, compared to say 60 years
ago. Nonetheless, it still isn't enough.
We know that we have to stop being
dependent on fossil fuels. Our current carbon dioxide emissions are
unsustainable, and the IPCC agrees that only immediate action will
avoid the worst, no matter which prediction model you look at among
the peer reviewed and accepted scenarios. We are too late to avoid an
impact already, so we will have to mitigate and adapt, but to avoid
the worst we have to act now.
The problem is, human behaviour is not
so easily changed. We like our traditions, we look at our individual
and immediate gain rather than for long-term benefits. In chapter
10.8 on Sustainability Ethics we have read that there are very few
ethics, despite it being the obvious thing to do, that care for our
offspring, our future generations. We tend to look at quick fixes,
some of which simply make things worse, e.g. sending sulphate
aerosols into the sky to deflect radiation, despite the side effects
that may make things worse for us. Our decision making follows the
same longing for immediate benefits. Our political systems elect
government into office for a stretch of a few limited years, and in
order to attract voters politicians promise whatever seems to be most
popular at the moment, which usually includes a reduction in taxes or
other monetary benefits for the wider population. We do want change,
but we don't want to pay for it. We don't realise that we will pay
for it if we continue like this, nobody else will pick up the tab for
their own pollution as long as they aren't forced to do so, and the
wider population will get stuck with the price to pay,
disproportionally affecting the poorer population.
Money also plays a part in policy
making and enforcement. The big money in energy business will
continue to encourage use of fossil fuels or nuclear power, and
influence policy and other governmental decisions with monetary
incentives, either in direct bribery, or by contributing in some
other, legal or semi-legal, way to a country's economy, leaving us
with increasing carbon emissions and nuclear waste that has nowhere
to go. Still, our dependency on energy and other consumption leading
to pollution is something that is difficult to give up, and most
people will continue to strive for this lifestyle, so what we really
need is a change in behaviour to accept alternatives that may be
slightly inferior at this stage. However, without more pressure from
the majority of the population nothing will change anytime soon. Not
until it is too late.
In conclusion, we do have the means
available to avoid the worst catastrophes, but that will involve us
humans learning to change our behaviour. We have to use less energy,
consume less fossil-fuel-dependent goods, eat less meat, and in
general, behave in a more environmentally-friendly way. It may not
seem much, but every little helps. And only by starting with the
little things will we convince decision-makers to enforce change in
the big things. We all have to learn, we all have to change, it is
too late to stay with business as usual. And I feel very tempted to
end with an encouraging “let's start today”, but it will be yet
another years or decades before enough of us have realised the need
for change to make an impact big enough to really mitigate climate
change. I am sure we will get there. We have no other choice.
