That Was Easy: In Just 60 Years, Capitalism Has Nearly Broken Planet Earth
New studies show how various forms of human activity, driven by a flawed economic system and vast consumption, is laying waste to Earth's natural systems. What are the "tipping points" the human race should not cross?
Humanity’s rapacious growth and accelerated energy needs over the
last generation—particularly fed by an economic system that demands
increasing levels of consumption and inputs of natural resources—are
fast driving planetary systems towards their breaking point, according
to a new pair of related studies.
“It is difficult to overestimate the scale and
speed of change. In a single lifetime humanity has become a geological
force at the planetary-scale.” —Prof. Will Steffen
Prepared by researchers at the Stockholm Resilience Centre, the first
study looks specifically at how “four of nine planetary boundaries have
now been crossed as a result of human activity.” Published in the journal Science* on Thursday, the 18 researchers involved with compiling evidence for the report—titled ‘Planetary Boundaries 2.0‘—found
that when it comes to climate change, species extinction and
biodiversity loss, deforestation and other land-system changes, and
altered biogeochemical cycles (such as changes to how key organic
compounds like phosphorus and nitrogen are operating in the
environment), the degradation that has already take place is driving the
Earth System, as a whole, into a new state of imbalance.“Transgressing a boundary increases the risk that human activities could inadvertently drive the Earth System into a much less hospitable state, damaging efforts to reduce poverty and leading to a deterioration of human well-being in many parts of the world, including wealthy countries,” said Professor Will Steffen, a researcher at the Centre and the Australian National University, Canberra, who was lead author for both studies.
In addition to the four boundaries that have already been crossed, the study looked at five other ways in which the planetary systems are under assault by human activity. They include: stratospheric ozone depletion; ocean acidification; freshwater use; atmospheric aerosol loading (microscopic particles in the atmosphere that affect climate and living organisms); and the introduction of novel entities into ecosystems (e.g. organic pollutants, radioactive materials, nanomaterials, and micro-plastics).
“I don’t think we’ve broken the planet but we are creating a much more difficult world,” Sarah Cornell, another report author, told Reuters.
In this interview with Wired last year, Johan Rockström, executive director of the Stockholm Resilience Centre, described the idea about planetary boundaries in details:
Related to the findings of the first study, the second report examines what it calls the “Great Acceleration” and is an assessment of the speed and influence that specific factors have had in damaging the planetary systems described in Planetary Boundaries 2.0. Using a series of indicators, the study compares the relationship, over time, between 12 ‘socio-economic factors’—including economic growth (GDP); population; foreign direct investment; energy consumption; and water use—on one side with 12 ‘Earth system trends’—like the carbon cycle; the nitrogen cycle and biodiversity—on the other.
Using what it calls a “planetary dashboard,” the research charts the spread and speed of human activity from the start of the industrial revolution in 1750 to 2010, and the subsequent changes in the Earth System – e.g. greenhouse gas levels, ocean acidification, deforestation and biodiversity deterioration. The analysis found that increased human activity—and “predominantly the global economic system”—has unseated all other factors as the primary driver of change in the Earth System, which the report describes as “the sum of our planet’s interacting physical, chemical, biological and human processes.” The most striking, i.e. “accelerated,” changes to that system have occurred in the last sixty years.
“It’s clear the economic system is driving us
towards an unsustainable future and people of my daughter’s generation
will find it increasingly hard to survive. History has shown that
civilisations have risen, stuck to their core values and then collapsed
because they didn’t change. That’s where we are today.” —Prof. Will
Steffen“It is difficult to overestimate the scale and speed of
change. In a single lifetime humanity has become a geological force at
the planetary-scale,” said Steffen, who also led the Acceleration study.
The conclusion that the world’s dominant economic
model—a globalized form of neoliberal capitalism, largely based on
international trade and fueled by extracting and consuming natural
resources—is the driving force behind planetary destruction will not
come as a shock, but the model’s detailed description of how this has
worked since the middle of the 20th century makes a more substantial
case than many previous attempts.
“When we first aggregated these datasets, we
expected to see major changes but what surprised us was the timing.
Almost all graphs show the same pattern. The most dramatic shifts have
occurred since 1950. We can say that around 1950 was the start of the
Great Acceleration,” says Steffen. “After 1950 we can see that major
Earth System changes became directly linked to changes largely related
to the global economic system. This is a new phenomenon and indicates
that humanity has a new responsibility at a global level for the
planet.”
The paper makes a point to acknowledge that
consumption patterns and the rise of what has become known as the
Anthropocene Era does not fall equally on the human population and its
examination of the economic system which is underpinning planetary
destruction is one rife with inequality, in which certain populations
consume at vastly higher levels than others.
A worrying trend, notes the paper, is how a growing global middle class—exemplified by those in the BRICS nations of Brazil, Russia, India, China, and South Africa—is an increasing threat to the planet as the consumer mindset established in the OECD nations, particularly the U.S., spreads.
In an interview with the Guardian, Steffen spoke clearly about the overall impacts of the two new studies as he sounded the alarm over humanity’s trajectory. “People say the world is robust and that’s true, there will be life on Earth, but the Earth won’t be robust for us,” he said. “Some people say we can adapt due to technology, but that’s a belief system, it’s not based on fact. There is no convincing evidence that a large mammal, with a core body temperature of 37C, will be able to evolve that quickly. Insects can, but humans can’t and that’s a problem.”
“It’s clear the economic system is driving us towards an unsustainable future and people of my daughter’s generation will find it increasingly hard to survive. History has shown that civilisations have risen, stuck to their core values and then collapsed because they didn’t change. That’s where we are today.”
What increasing amounts of strong evidence shows, he said, is that there are “tipping points” the human race should simply not “want to cross.”
