One potentially useful metric to measure how different nations value their biodiversity is just how much of a country’s land its government sets aside to protect its natural heritage and resources. While this might not necessarily cover all the aspects of ‘environment’ we need to explore, we know from previous research that the more emphasis a country places on protecting its biodiversity, the more it actually achieves this goal. This might sound intuitive, but there is no shortage of what have become known as ‘paper parks’ around the world, which are essentially only protected in principle, but not in practice.
For example, if a national park or some other type of protected area is not respected by the locals (who might rightly or wrongly perceive them as a limitation of their ‘rights’ of exploitation), or is pilfered by corrupt government officials in cahoots with extractive industries like logging or mining, then the park does not do well in protecting the species it was designed to safeguard. So, even though the proportion of area protected within a country is not a perfect reflection of its environmental performance, it tends to indicate to what extent its government, and therefore, its people, are committed to saving its natural heritage.
The global human population is now over 7.5 billion, and increasing by about 90 million each year. This means that we are predicted to exceed 9 billion people by 2050, with no peak in site this century and a world population of up to 12 billion by 2100. These staggering numbers are the result of being within the exponential phase of population growth since last century, such that some 14% of all human beings that have ever lived on the planet are still alive today. That is taking into account about the past 200,000 years, or 10,000 generations.
Of course just like the Earth’s resources, human beings are not distributed equally around the globe, nor are the population trends consistent among regions or nations. In fact, developing nations are contributing to the bulk of the global annual increase (around 89 million per year), whereas developed nations are contributing a growth of only about 1 million each year. Another demonstration of the disparity in human population distributon is that about half of all human beings live in just seven countries (China, India, USA, Indonesia, Brazil, Pakistan, Nigeria, and Bangladesh), representing just one quarter of the world’s total land area.

Apologies for the little gap in my regular posts — I am in the fortunate position of having spent the last three weeks in the beautiful Villa Serbelloni in the village of Bellagio on the shores of Lake Como (northern Italy) engaged in writing a new book with my good friend and colleague, Professor Paul Ehrlich. Both of us received an invitation to become ‘Bellagio Centre Residents‘ by the Rockefeller Foundation to write the book in, shall we say, rather lush circumstances.
While I can’t yet give away all the juicy details of the book itself (we’ve only written about a third of it so far), I wanted to give you a little taste of some of the interesting results we’ve so far put together.
Today’s topic is on human health, which as I’ve written many times before, is in many ways linked to the quality of the environment in which people live. We are currently looking at which countries have the best human health statistics, as well as the best environmental conditions in which to live. Read the rest of this entry »
In March 2016 I requested nominations for the Environmental Arsehat of the Year, and you happily complied by providing many excellent suggestions.
I now request that you vote on these nominations using the polling widget that follows a brief description of each nominee and why they’ve been suggested by the CB.com community. Once the votes are tallied, I’ll post the ‘winner’ (loser) in a new post in early 2017. Happy voting!
The nominations (in no particular order)
I’ve been thinking about this post for a while, but it wasn’t until having some long, deep chats today with staff and students at Simon Fraser University‘s Department of Biological Sciences (with a particular hat-tip to the lovely Nick Dulvy, Isabelle Côté & John Reynolds) that the full idea began to take shape in my brain. It seems my presentation was a two-way street: I think I taught a few people some things, and they taught me something back. Nice.
There’s no question at all that science communication has never before been so widespread and of such high quality. More and more scientists and science students are now blogging, tweeting and generally engaging the world about their science findings. There is also an increasing number of professional science communication associations out there, and a growing population of professional science communicators. It is possibly the best time in history to be involved in the generation and/or communication of scientific results.
Why then is the public appreciation, acceptance and understanding of science declining? It really doesn’t make much sense if you merely consider that there has never been more good science ‘out there’ in the media — both social and traditional. For the source literature itself, there has never before been as many scientific journals, articles and even scientists writing. Read the rest of this entry »
I’m starting a new series on ConservationBytes.com — one that exposes the worst environmental offenders on the planet.
I’ve taken the idea from an independent media organisation based in Australia — Crikey — who has been running the Golden Arsehat of the Year awards since 2008. It’s a hilarious, but simultaneously maddening, way of shaming the worst kinds of people.
So in the spirit of a little good fun and environmental naming-and-shaming, I’d like to put together a good list of candidates for the inaugural Environmental Arsehat of the Year awards.
So I’m keen to receive your nominations, either privately via e-mail, the ConservationBytes.com message service, or even in the comments stream of this post. Once I receive a good list of candidates, I’ll do separate posts on particularly deserving individuals, followed by an online poll where you can vote for your (least) favourite Arsehat.
There are a few nomination rules, however. Read the rest of this entry »

It. Has. Finally. Been. Published.
Yes, my new book with Paul Ehrlich, published by University of Chicago Press, is now available to purchase in book shops and online distributors around the world. The blog post today is a little explanatory synopsis of why we wrote the book and what it contains, but of course the real ‘meat’ is in the book. I hope you enjoy it.
In Australia, you can purchase the hard copy through Footprint Books, and the Kindle version at Amazon Australia. I also suggest that Australians might find the best deals through Booko. Electronic versions are also available through Kobo and Google Play. In the US you can order directly from University of Chicago Press, Amazon, Barnes & Noble, and many other book sellers. In the UK and Europe, the book is available from your country’s Amazon distributor. I imagine many chain and independent book sellers will be carrying the book by now, or will be soon.
My deepest thanks to all those who made it possible.

Our chance meeting in 2009 at Stanford University turned out to be auspicious, not least of which because of the publication this week of our co-authored book, Killing the Koala and Poisoning the Prairie. Australia, America and the Environment by University of Chicago Press. As a mid-career ecologist (Bradshaw) based at the University of Adelaide, it was indeed an honour to meet one of the most famous scientists (Ehrlich) in my field. With a list of books and hundreds of scientific papers under his belt, Ehrlich has been tackling major environmental issues since the 1960s. Ehrlich also has a long-time interest in Australia, having visited nearly every year during the last four decades and experienced more of the country than most Australians. Together we have observed firsthand the similarities and differences of Australia and the US, and the eyes we see through are trained as those of environmental scientists and evolutionary biologists.
So why write a book about the environmental tragedies currently unfolding in two completely different countries at opposite ends of the Earth? As it turns out, Australia and the US have much more in common environmentally than one might think, and not necessarily in a good way. Despite our vastly different floras and faunas, population densities, histories of human colonisation and soil productivities, there is an almost spooky similarity in the environmental and political problems both our countries are now experiencing. As such, we have a lot to learn about avoiding each other’s mistakes.

Australia and the contiguous US are roughly equivalent in land area, both cultures are derived originally and principally from what is now the United Kingdom, and both are examples of super-consuming, super-wasting, wealthy, literate countries. Both countries also have environmental footprints that exceed most other countries on Earth, with some of the world’s highest per capita rates of greenhouse-gas emissions, water consumption, species extinctions and deforestation.

It probably won’t come as too much of a surprise that most of the people I know reasonably well (mates included) are also scientists of some description. I therefore think that I fall into the extremely normal and mundane category of associating the most with people at work. Sure, I’ve also got very good mates who are et alia plumbers, chefs, winemakers (I do live in South Australia, after all), mechanics, coffee roasters and farmers (I also live on a small farm), so at least a get out of the office a bit. In summary, I tend to befriend and hang around people who are for the most part making ends meet, but who are by no means in a position to spend oodles of cash on anything remotely related to the conservation of biodiversity.
From time to time, however, I do meet extremely wealthy people, but we generally do not operate in the same social circles (I know, another big surprise). Nonetheless, I keep finding myself in conversations with such people that start along the lines of the following question:
“What’s the most effective way to invest money to save species from going extinct?”
As the Australian saying goes: “How long is a piece of string” – in other words, it’s a difficult, multi-dimensional answer at best, or a confused non sequitur one at worst.
Those reading this might be thinking right now, “Oh, I know exactly what I’d spend it on if I had that kind of money”, but after a few moments of contemplation, you might not be so sure. This is the dilemma in which I’ve found myself now on more than a few occasions.
So, with the benefit of a little contemplation, here are a few of my thoughts on the subject. Read the rest of this entry »
If, for the purposes of some sick and twisted thought experiment, you were to design policies that would ensure the long-term failure of a wealthy, developed nation, you wouldn’t have to look farther than Australia’s current recipe for future disaster. I’m not trying to be provocative, but the warning signs are too bold and flashy to ignore. Let’s just run through some of the main ones:
1. As the lambasted and thoroughly flawed 2015 Intergenerational Report clearly demonstrates, our current government has no idea about the future threats of climate change. Dragged kicking and screaming into only a symbolic recognition of some ‘distant and currently irrelevant problem’, the Abbott-oir and his intergenerational criminals are well known for killing the carbon-pricing scheme, dismantling the Department of Climate Change, pulling out of major international talks on climate-change mitigation and installing a half-arsed, ineffective policy that will do nothing to stem our emissions. Combine that with comments like “coal is good for humanity“, and it’s easy to see how our current leaders have little idea about the future mess they’re creating.
2. Not content just to kick the shit out of any meaningful climate action, our government has also turned its back on any renewable energy target, and facilitated the fossil-fuel barons to dig more coal out of the ground. While South Australia’s Royal Commission on the nuclear fuel cycle is a welcome candle in the climate change-mitigation darkness here, it is far from becoming a national priority any time soon.
3. As has been well documented, the Abbott-oir ship of fools has also done whatever it can to turn back decades of environmental protections in less than six months of taking office. Everything from opening up national parks for exploitation, failing to protect marine sanctuaries, limiting environmental checks to promoting logging in World Heritage Areas, there is little room for hope that our crumbling environmental system will improve at all in the near to long term.

Tone Abbott-oir, easily the most environmentally destructive Prime Minister this country has seen in the modern era, has survived the party room spill for a leadership change. Although 39% of his own Fiberal Party MPs voted to dump him, he remains standing (limping) – for now.
I’ve seen rather a lot lately in the Australian media about the impending spill vote, and the potential political repercussions of a change (or not), but there’s been nearly no mention of what it all means for the continually degrading Australian environment.
As is typical in Australian politics, the environment takes a very distant back seat to the those oh-so-important societal issues like knighthoods, paid parental leave and where to put the next road in Melbourne, so I certainly wasn’t hopeful that a leadership change (or not) would have any positive environmental outcomes. This particular latte-snorting, quinoa-flavoured-pinot-grigio-in-the-artisanal-underpants-pouring, erect-nipple-paper-rubbing environmental scientist has nothing at all to celebrate, even if the no-confidence in The Great Red Underpants is potentially a positive sign.
