Preventing the next pandemic

ASU professor says environmental degradation may be a root cause of pandemics, vulnerabilities

June 17, 2020

“We seem to have lost sight of the deeper drivers of an accelerating risk of infectious disease transmission to the world,” wrote Leah Gerber, professor of conservation science and director of the Center for Biodiversity Outcomes at Arizona State University, in a recent piece for Issues in Science and Technology, referring to the root causes of the coronavirus pandemic.

“Environmental degradation, and especially habitat destruction, is the underlying problem that creates conditions favorable to zoonotic jumping.”

Experts worldwide have been focused on trying to quell rising cases. Gerber is sounding the alarm that we need to focus on how the pandemic started to prevent history from repeating itself in the near future. On June 11, Gerber led “A Global Strategy for Preventing the Next Pandemic,” a discussion hosted by ASU’s Consortium for Science, Policy and Outcomes. She explained how environmental degradation could be the underlying problem that led to the mass spread of COVID-19 — and which is also causing other unprecedented threats to humanity.

“When we degrade biodiversity, this increases the risk of zoonosis, and a zoonotic disease is one that spreads from animals to humans,” Gerber said. “This is what we experienced with the COVID pandemic.”

Gerber emphasized that the factors contributing to the spread of COVID-19 among humans are mainly issues that humans caused, such as habitat destruction.

A related phenomenon caused by human interference with wildlife and their habitats is mass extinction, which Gerber says will lead to much lower biodiversity on Earth. Past mass extinctions have been natural, which Gerber notes makes this one quite different.

“There have been five mass extinctions on Earth, and data suggest we’re in the middle of a sixth mass extinction — one that is specifically caused by humans,” Gerber explained. “What happens when we have a pandemic during a mass extinction? The same factors that have put biodiversity at risk make us vulnerable to pandemics.”

Gerber believes the global community must come together to track how human activity is causing zoonotic diseases like COVID-19 through a new organization.

There are already public-health organizations with a global reach, such as the World Health Organization. But Gerber’s organization would have a more comprehensive remit. This new organization, which Gerber calls the Zoonotic Disease Commission, could accomplish three things: support communication of basic science; provide global governance with regulatory clout; and transform the global economy to create markets that can minimize risk.

“It can be a problem when we have nonbinding global agreements to try and work together and promote governance, and I’m also not seeing discussion about incentives or market-based solutions in existing institutions,” Gerber said.

Gerber hopes that the world will be inspired to take this sort of global action to mitigate the loss of biodiversity and the risk of future pandemics.

“When the COVID virus hit I thought maybe this could be a way to reach people because it’s actually impacting us,” Gerber said. “It’s not just about being altruistic anymore.”
