Urgency to protect nature, or up to 850,000 animal viruses could be caught by humans

UN report says up to 850,000 animal viruses could be caught by humans, unless we protect nature, The Conversation   Katie Woolaston, Lawyer, Queensland University of Technology, Judith Lorraine Fisher, Adjunct Professor University of Western Australia, Institute of Agriculture
October 30, 2020   Human damage to biodiversity is leading us into a pandemic era. The virus that causes COVID-19, for example, is linked to similar viruses in bats, which may have been passed to humans via pangolins or another species.Environmental destruction such as land clearing, deforestation, climate change, intense agriculture and the wildlife trade is putting humans into closer contact with wildlife. Animals carry microbes that can be transferred to people during these encounters.

A major report released today says up to 850,000 undiscovered viruses which could be transferred to humans are thought to exist in mammal and avian hosts.

The report, by The United Nations’ Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), says to avoid future pandemics, humans must urgently transform our relationship with the environment.

Humans costs are mounting

The report is the result of a week-long virtual workshop in July this year, attended by leading experts. It says a review of scientific evidence shows:

…pandemics are becoming more frequent, driven by a continued rise in the underlying emerging disease events that spark them. Without preventative strategies, pandemics will emerge more often, spread more rapidly, kill more people, and affect the global  economy with more devastating impact than ever before.

The report says, on average, five new diseases are transferred from animals to humans every year – all with pandemic potential. In the past century, these have included:

  • the Ebola virus (from fruit bats),
  • AIDS (from chimpazees)
  • Lyme disease (from ticks)
  • the Hendra virus (which first erupted at a Brisbane racing stable in 1994).
The report says an estimated 1.7 million currently undiscovered viruses are thought to exist in mammal and avian hosts. Of these, 540,000-850,000 could infect humans.
But rather than prioritising the prevention of pandemic outbreaks, governments around the world primarily focus on responding – through early detection, containment and hope for rapid development of vaccines and medicines…..

Finally, Australia is one of few countries without a national centre for disease control and pandemics.

But there are good reasons for hope. It’s within Australia’s means to build an organisation focused on a OneHealth approach. Australia is one of the most biologically diverse countries on the planet and Australians are willing to protect it. Further, many investors believe proper environmental policy will aid Australia’s economic recovery.

Finally, we have countless passionate experts and traditional owners willing to do the hard work around policy design and implementation.

As this new report demonstrates, we know the origins of pandemics, and this gives us the power to prevent them……  https://theconversation.com/un-report-says-up-to-850-000-animal-viruses-could-be-caught-by-humans-unless-we-protect-nature-148911
