In the wake of the stark revelations presented at COP28, the spotlight has turned, with greater urgency, to the underlying crisis fuelling climate change: the human behavioural crisis. Joseph Merz, the lead author of a compelling new study, declares, “We have socially engineered ourselves the way we geoengineered the planet.” This statement encapsulates the crux of our environmental predicament.
Merz’s research, conducted at the Merz Institute, identifies a fundamental flaw in our approach to climate solutions. We have been addressing symptoms, not the root cause. The root cause, as Merz’s team argues, is the ecological overshoot driven by our insatiable consumption, rampant waste, and burgeoning population. These are the levers pulling us ever further from ecological balance.
Consumerism is accelerating climate change
The concept of overshoot is critical here. It is the idea that humanity is using resources at a rate that exceeds the Earth’s capacity to regenerate them. We are, in essence, living as if we had 1.7 Earths at our disposal. This overconsumption is not just about carbon emissions; it is about the broader ecological impact of our material usage, waste, and population growth.
Merz’s team delves into the neuropsychological and social factors driving these unsustainable behaviours. They argue that our ancient drives—such as the need to belong, signal status, or attract a mate—have been exploited by marketing strategies, creating a paradigm fundamentally at odds with sustainable living. This manipulation of human behaviour, if left unchecked, could lead us to ecological and societal collapse.
However, history offers examples of successful shifts in societal norms for the greater good. Public health campaigns advocating for handwashing and immunisations dramatically reduced the spread of deadly diseases. Similarly, movements promoting LGBTQ+ rights and racial equality have spurred monumental social changes. By harnessing the power of collective action and leveraging effective communication strategies, we can also transform our relationship with the environment.
We must foster a global cultural shift, one that celebrates frugality, responsible consumption, and respect for ecological boundaries. This cultural revolution needs to permeate every aspect of society, from education and media to economic systems and policy initiatives. Only through such a collective effort can we truly escape the grip of the behavioural crisis and build a sustainable future for all.
The paper also sheds light on a disturbing fact: a mere quarter of the global population is responsible for almost three-quarters of emissions. This disproportionate impact calls for a radical rethinking of our material-intensive social norms. We need to shift our values and aspirations towards those with minimal or positive ecological footprints.
The Merz Institute is not just theorising; they are actively working to counteract this crisis. Their Overshoot Behaviour Lab focuses on identifying and influencing key behavioural drivers. They target influencers in various sectors, like entertainment and technology, to promote sustainable social norms. This approach mirrors the successful strategies of the Population Media Centre, which uses mainstream entertainment to effect positive behavioural changes, such as reduced fertility rates.
Addressing population growth is delicate but crucial. As Merz’s team points out, this is not just a matter of numbers; it is about empowering women through education and liberating choices.
The paper calls for an interdisciplinary effort to redefine and reshape our desires and norms that drive overconsumption. This is not a mere academic exercise; it is an ethical imperative. As corporations manipulate our psychology for economic gain, contributing to the planet’s destruction, we must counteract this with creativity and innovation that promote sustainability.
The message is clear: we are at a crossroads. The evidence indicates that our current approach, focusing primarily on physical interventions like renewable energy, is insufficient and potentially counterproductive. The real solution lies in addressing the behavioural crisis. We need an interdisciplinary, concerted effort to redefine global consumption, reproduction, and waste norms. Only then can we hope to avert the catastrophic consequences of ecological overshoot and ensure a sustainable future for humanity and the myriad other species with whom we share this planet.
The clock is ticking. As societal breakdown looms on the horizon, worsened by the effects of overshoot, our window for proactive, coherent action is narrowing. While the challenges ahead are immense, they are not insurmountable. We possess the ingenuity and resources to engineer a world that thrives within planetary boundaries. We have the capacity for empathy and foresight to prioritise the well-being of future generations and the diversity of life on Earth. The time for delay and incremental change is over.
We must now summon the collective courage and determination to embark on a bold transformation. It requires a revolution in our thinking, a redefinition of our values, and a commitment to working together across disciplines and borders. The future of our planet and its inhabitants hangs in the balance. Let us choose the path of collective action, ecological stewardship, and shared prosperity.
This is not just an environmental imperative; it is a moral obligation for the sake of present and future generations. It is imperative that we seize this opportunity, using the intact systems at our disposal, to foster a global shift in behaviour. If we fail, we risk locking the planet into a recovery that might save nature but leave it inhospitable for human life.
