Extinction Anxiety

21 05 2020

Earlier this week, the SBS show The Feed did a short segment called ‘Extinction Anxiety’ where I talked with host Alice Matthews about biodiversity extinctions. Given that it has so far only been available in Australia, I made a copy here for others to view.

For more information on the state of global biodiversity, see this previous post.

Never let a good crisis go to waste

Winston Churchill’s words have never been more important than today as we experience the society- and life-changing consequences of the COVID-19 pandemic.

The extent and severity of the disease is a result of ignoring decades of warnings by scientists about the general deterioration of humanity’s epidemiological environment, and specific warnings about confining live, wild animals in markets. The situation was made even more lethal by ignoring the warnings from epidemiologists and disease ecologists once it became clear that an imminent pandemic most likely arose from this practice. Many countries, including the United States, are still ignoring those warnings and the required actions to lessen the impact.

Accordingly, we should ask ourselves, “what else are we missing?” What other huge problems are hiding in plain sight where science could guide policy to avoid catastrophic future failures? For instance, there are two principal health threats that must be addressed immediately, and we must strike while the iron is hot.

The overuse of antibiotics in agriculture will cause widespread deaths from formerly treatable bacterial diseases because of the evolution of antibiotic resistance in microbes. The evolution of resistance is well-known, predictable, and obvious — not in retrospect, but now. By feeding antibiotics to otherwise healthy livestock, animals can be housed in higher densities and they grow faster. Read the rest of this entry »





Shifting from prevention to damage control

5 05 2020

timeBack in March this year before much of the world morphed into the weirdness that now dictates all facets of life, I wrote an update for the Is This How You Feel project led by Joe Duggan.

It was an exercise in emotional expression not necessarily grounded in empiricism. But in that particular piece, I had written the following line:

Few scientists in my field are still seriously considering avoidance of environmental collapse; instead, the dominant discourse is centred on damage control.

But is this correct? Is this how most scientists in conservation feel today? In a way, this post serves both as a rationale for my expectation, and as a question for the wider community.

My rationale for that contention is that it is undeniable that biodiversity is going down the toilet faster than even some of the most pessimistic of us could have predicted. We are without doubt within the sixth mass extinction event every experienced on the Earth for at least the last 600 million years.

Yet, there have never been more conservation biologists and practitioners. There have never been more international treaties and accords that expressly aim to protect biodiversity.

To assert that we have failed is unhelpful fatalism, yet it cannot be ignored that biodiversity’s predicament and those charged with turning around its fate are not exactly replete with successes. Read the rest of this entry »
