The sustainability movement on
American campuses is incredibly powerful. The problem is that it is unclear
what sustainability is or whether it is worth pursuing.
Universities are focusing on sustainability
with religion-like fervor. According to the Association for the Advancement of
Sustainability in Higher Education (AASHA), there roughly 1,300 environmental
programs in the U.S., with at least one program in each state. According to the
U.S. Colleges and University Presidents’ Climate Commitment, roughly 700
colleges and universities signed a pledge to eliminate or offset all greenhouse
gas emissions and to integrate sustainability into the curriculum. AASHA reports
that there are now more than 400 student-led fossil fuel divestment campaigns
in the U.S. Twenty-two U.S. universities have announced plans to eliminate
their investments in fossil fuels. Hundreds of U.S. universities submit to an
environmental tracking and rating system.
The conservative faculty group,
National Association of Scholars, argues that the sustainability movement has
further politicized many campuses by making sustainability an educational
commitment rather than an idea to be discussed and debated. It also charges
that campuses are spending large amounts of money on sustainability projects
and positions and doing so in ways that are not financially transparent.
One problem with this movement is
that it is not clear what sustainability is. Dictionary.com defines
“sustainability” as “the quality of not being
harmful to the environment or depleting natural resources, and thereby
supporting long-term ecological balance.”
One
concern is what time period is relevant to long-term ecological balance. There
are roughly 7.5 billion people on the planet. This is historically
unprecedented. As recently as 10,000 years ago, there were no more than a few
million people. There were not even one billion people until the 1800’s and
only two billion in the 1920’s. The population could explode to reach 10
billion by the middle of the century. It is unclear if the long-term ecological
balance is that found with 7.5 billion people or an earlier period with far
fewer people. A later baseline allows for more pollution than does an earlier
baseline. Picking one time period rather than another, though, is arbitrary and
good policy should not depend on an arbitrary baseline.
A second concern here is whether the ecological balance that
matters for sustainability changes over time. Eco-systems change with the
changing climate and evolution. The last ice age ended 10,000 years ago and it
included a different set of mammals. This included mammoths, mastodons, giant
ground sloths, massive cousins of the armadillo (Glyptodon), giant ground
sloths, heavy ancient wolves (dire wolves), giant short-faced bears, and so on.
Over the long run, animal and plant species come and go along with natural
climate change and new competitors. It is implausible that people should try to
protect some species against potential replacements.
If people have no duty to protect current plant and
animal species that are threatened by natural changes in the environment, then
it is unclear why they have a duty to protect them when they are threatened by
manmade changes in the environment. That is, it is hard to see what moral duty
allows people to sit idly by when a natural change in the environment wreaks
havoc on some types of animals, but requires them to spring into action when manmade
changes have the same effect.
If the concern is instead that harm to the environment
will endanger people’s health and lives, then a third concern arises, namely,
whether sustainability is designed to protect people or the environment. The
two can, and sometimes do, diverge. Eliminating all manmade greenhouse gases in
the near future would be unbelievably expensive. It would make billions of
people poorer, shorten lives, and worsen health. Still, eliminating these gases
might preserve various eco-systems. The question is whether sustainability aims
to protect eco-systems, protect people’s well-being, or both. If it aims at
both, then there is the issue of how to trade off people’s interests against those
of the environment (specifically, the interests of animals who inhabit the
environment). Without a deeper theory to explain whether there should be
tradeoffs and how to think of them, the goal of sustainability is arbitrary and
unjustified.
Philosophy provides various theories that would explain
how to trade off animals’ and people’s interests. The best of them, utilitarianism,
tells us that we should adopt those policies that maximize pleasure among all
individuals, regardless of whether it is a person or animal. The problem is that
if additional people lower utility by displacing too many animals, then such a
theory would require that there be far fewer people and their consumption be cut
back. This might be done by harshly taxing couples for having more than one
child (or, perhaps, incarcerating them) and curtailing immigration from poor
countries to rich ones. This might also be done by a host of new and onerous
taxes on energy use, such as a value-added tax and higher taxes on gas, roads,
cars, flights, and so on.
Worse,
utilitarianism might require that people artificially change environments so
that they support more utility-enjoying animals. This opens the door to
questions such as whether there are too many or too few killer whales or
elephants in the same way that it opens the door to whether there are too many
or too few Chinese or Indians. Utilitarianism does not necessarily require that
we not harm the environment. If utilitarianism justifies sustainability, then
sustainability is not a fundamental goal.
A
fourth concern is what constitutes harm to the environment. There is an issue
as to whether it consists of a setback to the number of species (diversity),
amount of life (biomass), or some combination of these things. If it consists
of a combination, then, again, we need a justification of when a loss of one at
the expense of the other would constitute harm. In addition, further issues
arise such as whether the mere addition of a species to an environment that
lessens neither diversity nor biomass harms the environment.
In the absence of a principled theory, sustainability
should not be given so many resources in academia. Universities should
reconsider their sustainability faculty and staff hires, dazzling array of
sustainability classes, recycling and other environmental programs, etc. Also,
the unquestioning commitment to sustainability should be revisited. No longer
should it receive the faith-based acceptance that is more appropriate for a
religion than a campus program of study.
