There is nothing like a pandemic of disease to whip up hysteria and fear in human populations yet scientists have been warning about the likelihood of the emergence of these viruses for decades. When it comes to zoonotic spillover viruses these things at least hypothetically should have a silver lining when it comes to highlighting to the public the link between ecological disequilibrium through our impact on the natural world and widescale human mortality.
But after having witnessed over the years the well founded media and public hysteria regarding "mad cow disease", foot and mouth disease, AIDS/HIV, SARS, Ebola, Zika, yellow fever, Swine flu and bird flu I can't help but be very cynical. It appears to me that pandemics are something like climate change, antibiotic resistance or terrorism in the sense that non-scientists/analysts and policy makers only really worry about when it finally hits us.
The rest of the time people just go sleep walking blithely through their lives and don't care about what is going on in the wider world. When the **** hits the fan a virus will typically become a talking point for a while and then eventually be largely forgotten by all but survivors and scientists until the next one arises. The fact that these pandemics are essentially an ecological blowback seems to be conveniently ignored by the majority.
I hope the emergence of the Coronavirus at least highlights the relevance and need of effective conservation policies to people and leads to a far greater political and economical will towards investment in these I don't actually hold out much hope.
I agree with your central point, that societies and policy makers should be concerned with the relation between human health and disease outbreaks and conservation and ecological policy. I guess your cynicism regarding where on the priority list this topic is is largely warranted. I believe we need to be watchful, take appropriate action, invest and make changes. I also hope some lessons will be learned from Covid-19, but I doubt they will be - I wouldn't be surprised if, for example, China would again lift its ban on wildlife trade. Some of this bad crap is too ingrained for it to go away even with strong legal action by willing governments.
However with regards to people living their lives while ignoring these issues, I would like to point out that very few are able or willing to live their lives constantly worrying about things that could do wrong or constantly calling for conservation and environmental action. Even of those who are concerned about conservation and the environment (like I would guess most people on this site) few can or want to dedicate their entire life towards these matters. There is still such a thing as enjoying life. It is good to be concerned, but few can or want to let that concern rule their entire life.
PS: Some of these discussions should probably be moved to the Covid-19 thread, if possible.
