Mother Nature fights back


GOVERNMENTS AROUND THE world must urgently recognise the role of human behaviour, human populations and their development practices as the world faces pandemic disease like COVID-19. That’s the conclusion of an overdue research focus on the ground-level drivers of novel diseases besetting the globe.

The latest coronavirus disease started as a result of humans eating wildlife or otherwise being infected by wildlife caged for human consumption (a cultural practice that the Chinese government has now banned). Within months of the initial event in China, the whole world has gone into lockdown and economies into meltdown thanks to pandemic spread of the virus.

Other recent zoonotic viral diseases, like SARS, that spread through some Asian countries emerged due to similar behaviours. Ebola in Africa is another example of the dangers of eating bushmeat — monkeys, apes in that case. AIDs had similar genesis. (Zoonotic refers to the ability of pathogens to jump between species. Domesticated animals can be intermediary hosts from wildlife. The novel diseases that emerge are the result of human hosts with no immunity to the viruses carried by other animals.)

Australia’s CSIRO recently published an article in its science magazine ECOS on research outlining the case against human mal-interaction with the natural environment and the disastrous health impacts.

“Scientists from the different disciplines within CSIRO, the American-based EcoHealth Alliance, and the Sapienza University of Rome in Italy are embarking on new territory where they are encouraging governments and communities world-wide to recognise and address the interactions between environmental change and infectious disease emergence.

“This research is outlined in a paper titled Sustainable development must account for pandemic riskwhich has been published in the PNAS scientific journal, “ wrote ECOS journalist Amy Edwards.

What is driving this pandemic and other wildlife-borne diseases?

Increasing habitat invasion and biodiversity destruction as well as the lucrative and criminal world wildlife trade are the major drivers of a threat to human civilisation as we know it that rivals that other nature fightback, climate disruption.

Australians are no longer strangers to either the impacts of climate change or to massive habitat and biodiversity destruction for economic gain. It has been harder to ignore the ecosystem loss of the Murray Darling in the past 12 months, or the mounting cost of 200 years of native vegetation and wildlife removal, on behalf of farming and development.

And while censuring the Chinese for eating and trading in bats and pangolins Australians might also want to face the world’s most extensive and still unpublicised land-based wildlife slaughter. It occurs right here at home with the kangaroo trade for meat, (yes, bushmeat with a documented history of hygiene issues), and for wildlife skins to make football boots and other consumer products.

70% of new infectious disease related to pressure on wildlife

The paper in the Proceedings of the National Academy of Science of America that informed the CSIRO story (linked above) notes what is very evident: reaction to a string of novel diseases has been almost totally reactive and human-society focused without looking at the larger picture. Yet 70% of new infectious diseases in recent decades and most pandemics are related to human interaction with wildlife and natural habitat.

The research points to deforestation, expansion of agricultural land, intensive animal raising, and increased hunting and trading of wildlife as driving this ongoing global train wreck.

Put simply, the world’s terrestrial ecosystems are at increasing risk and their remaining inhabitants are in ever-closer contact with humans. War and people displacement; ever-larger human populations and resultant people migrations play their role in this disease/pandemic picture. One might add, as do global market economics and vastly increased leisure travel in the past 20 years.

Intensive livestock production another disease driver

The explosion of livestock production and intensive animal raising worldwide increases the risk of zoonotic diseases being transmitted by and through domesticated animals — poultry and swine flus being examples.

The authors of the PNAS paper look to action through global organisations including those of the UN — World Health, Food and Agriculture — to throw a spotlight on the interactions between humans, the natural world and the spread of disease. The current corona virus impacts that are destroying both human health and economies are centre stage.

Will governments do better than on combating climate change?

Gazing at that stage, will the response of those in power be better than we have experienced with the wobbly response to global climate disruption and its impacts? Remember the Australian bush fires? In both cases human behaviour, development goals and economic activities have been the driving forces.

The PNAS research concludes that ecological and farming knowledge needs swift expansion and integration, global planning and cooperation need to be the overarching umbrella — including more to stop the wildlife trade — and traditional thinking about expansion and development, needs to change. Are world governments, businesses and peoples prepared to listen, learn and act? The next two years will tell.


Coronavirus: ‘Nature is sending us a message’, says UN environment chief

Did the novel coronavirus known as COVID-19 really come from wild


China bans trade consumption of wild animals to counter virus



Humane Society International picked up the following radio interview between the Australian Prime Minister, Scott Morrison and, wait for it, Alan Jones.

Humane Society International said it welcomes the Prime Minister’s statement to Alan Jones on 2GB on 3 April signalling Australia will be strident in calling for a crack down on wildlife trade.

Wildlife markets have spawned or exacerbated global health crises with the current COVID-19 and earlier Severe Acute Respiratory Syndrome (SARS) and the deadly bird flu.

The Prime Minister made the point that these markets are not unique to China and present a risk wherever they operate in the world.

Is COVID-19 more successful than the IPCC?


COMMENT: 2020 is a vastly different year in Wuhan.

I AM BUNKERED in my study, my wife in her sewing room — being retired we are luckily not too impacted, but outside, business and leisure alike have come to a halt. Our children out of work, their children are out of school. The world seems to be closing down as the virus’ spread is brought under control. It is sadly bringing suffering, hardship and deaths. Yet with all this, some of my hopes for the future are happening today!

Electricity demand has reduced, transport’s fossil-fuel thirst has gone, emissions have fallen, the  air is clearing, and even the water has improved.

Of course the COVID-19 pandemic is not something anyone would wish for as a solution (though some suggest it might be Mother Nature’s plan) but like the GFC it seems to have been far more successful at reducing global emissions than even all the IPCC endeavours.

It’s good that most governments are taking the science seriously on the pandemic. Perhaps it’s helpful that each country’s response directly affect their own, quickly-realised outcomes, and with luck it should all be over in a year or two. Alas climate change is not afforded any of these luxuries yet I fear it will be more deadly than COVID-19 by far.

It’s good to see that our government can respond sensibly to an urgent global crisis. We only need to make them see that the right hand graph is even more important to address, needing not just to be flattened, but to be sent a long way south!

There are some other positives too. Maybe it will help people to see how seemingly simple issues can have major disruptions for society. Maybe our politicians will learn to trust science and consider more reasonably the need to turn around exponential growth..

And for CCL — well who would have thought — our conference last week was knocked on the head by COVID but ended up bigger in attendance and way down on travel and time for us all. It’s great to see this same approach in so many organisations too. People have stopped wasting their time and money travelling when they can work from home and meet on-line. Maybe this reduced carbon lifestyle is something that can stay with us long after the virus crisis has passed.

In the meantime, I sincerely hope COVID-19 and the isolation regimes have not impacted you or your family too badly, and that things will improve soon.

— Stay safe, Tom
