One World One People - One Health

The world is treating the health and economic symptoms of the coronavirus pandemic but not the environmental cause, according to the authors of a UN report. As a result, a steady stream of diseases can be expected to jump from animals to humans in coming years, they say. The report said a “one health” approach that unites human, animal and environmental health is vital.

The number of such “zoonotic” epidemics is rising, from Ebola to Sars to West Nile virus and Rift Valley fever, with the root cause being the destruction of nature by humans and the growing demand for meat, the report says.

Even before Covid-19, 2 million people died from zoonotic diseases every year, mostly in poorer countries. 

The coronavirus outbreak was highly predictable, the experts said. “Covid-19 may be the worst, but it is not the first,” said the UN environment chief, Inger Andersen. “The science is clear that if we keep exploiting wildlife and destroying our ecosystems, then we can expect to see a steady stream of these diseases jumping from animals to humans in the years ahead,” said Andersen. “At the heart of our response to zoonoses and the other challenges humanity faces should be the simple idea that the health of humanity depends on the health of the planet and the health of other species,” said Andersen. “If humanity gives nature a chance to breathe, it will be our greatest ally as we seek to build a fairer, greener and safer world for everyone.”

“There has been so much response to Covid-19 but much of it has treated it as a medical challenge or an economic shock,” said Prof Delia Grace, the lead author of the report by the United Nations Environment Programme (Unep) and the International Livestock Research Institute (Ilri). “But its origins are in the environment, food systems and animal health. This is a lot like having somebody sick and treating only the symptoms and not treating the underlying cause, and there are many other zoonotic diseases with pandemic potential.”
Wildlife and livestock are the source of most viruses infecting humans and the report cites a series of drivers of outbreaks, including rising demand for animal protein, more intensive and unsustainable farming, greater exploitation of wildlife, surging global travel and the climate crisis. It also says many farmers, regions and nations are reluctant to declare outbreaks for fear of damaging trade.
“The primary risks for future spillover of zoonotic diseases are deforestation of tropical environments and large-scale industrial farming of animals, specifically pigs and chickens at high density,” says the disease ecologist Thomas Gillespie of Emory University in the US, an expert reviewer of the report. “We are at a crisis point. If we don’t radically change our attitudes toward the natural world, things are going to get much, much worse. What we are experiencing now will seem mild by comparison.”
The blog can only comment that while it is quite correct that to cure a problem is not to treat just its symptoms but to address the core cause, but what is being overlooked by those experts is that it is capitalism which is creating the conditions for zoonotic diseases to arise.
