Protection of the environment is strongly associated with regulation of the human activities that threaten it, and regulation is usually administered by government. Although almost everyone would probably agree that some regulation is necessary, regulation has a patchy record when it comes to environmental protection. And there is another approach to achieving environmental goals. Free market environmentalism, instead of protecting nature from market forces, harnesses those forces to protect nature. Or at least that's the idea.

Ronald Bailey is the longtime science writer for Reason Magazine, a renowned American libertarian news & opinion outlet that’s been around for more than 50 years. Ron joins me to flesh out the case for free market environmentalism.

There are few environmental issues more emotive than the hunting of whales. Although the focus of environmentalists has shifted to other topics in recent times, whaling remains contentious whenever it is brought up. This is understandable considering that, for the first half of the 20th century and into the 1970s, several whale species were hunted to near-extinction. But as crude oil took over from whale oil as the fuel of industry whale populations began making impressive recoveries. Nevertheless, a handful of countries and populations continue to hunt them, much to the chagrin of the rest of the world. Perhaps the most high profile whaling country is Japan. To add to the saga, in 2019 Japan ended about seven decades of membership of the International Whaling Commission (IWC) - the global body responsible for the “management of whaling and conservation of whales”.

There are countless sources providing the anti-whaling point of view, to some of which I will provide links in the podcast description. But comprehensive accounts of the other side of the story are less easy to find. Joji Morishita has been, among many other things, Japan’s Commissioner to the IWC (2013 - 2018) and IWC Chair (2016 - 2018) and I doubt there is any better person in the world to tell Japan’s side of the whaling story. In this fascinating discussion he explains why Japan withdrew from the IWC, and he takes on many of the core arguments against whaling.

Agriculture has been by far the biggest driver of land change and land degradation worldwide. And yet, it is also fundamental to the very existence of humankind. This mismatch often comes up in public discourse. Over the past year or two, for example, several European countries have seen extensive farmer protests - against rising costs and restrictive environmental regulations, among other things. Environmental groups have responded to the farmers’ appeals mostly with indignation… and yet farmers and environmentalists have a lot in common - at east potentially.

Philippe Birker is co-founder of “Climate Farmers”, and his work is aimed mostly at promoting regenerative agriculture. He and I cover a range of topics in the discussion that follows, from the farmer protests to the relationship between agrochemical companies and government. Along the way, there were several “rabbit holes” that we could have gone down, and several points that I would have liked to challenge Philippe on in greater depth. But, with limited available time, I needed to bookmark most of these for another time and for future guests.

Insects are among the most abundant organisms on Earth. About 350,000 beetle species, alone, have been described by science and this is considered to be only a fraction of their total number. In a variety of ways, insects are a fundamental part of natural and human-adapted systems. While some cause disease or ruin crops, others play a key role in ecosystem service provision, for example by pollinating certain crops or as food for other beneficial animals and people. Overall, the loss of insect species is a major concern. Some of the more exuberant headlines broadcasting this message have gone so far as to declare an imminent “insectageddon”. However, although many insect species are declining or in danger of decline, there is reason to be wary of such excessive claims. Data need to be carefully considered, revealing the complex patterns of change. Unfortunately the media, in particular, is often incentivized to focus on the more extreme findings and neglect the nuances.

Jane Hill (OBE) is president of the Royal Entomological Society and a professor at the University of York. She helps me to pick apart the "insectageddon" idea, including how valid it is and how it came about in the first place.

Humankind’s transformation of the Earth is embodied in the idea that we are living in the “Anthropocene”. Most people who have heard of this concept were probably unaware that it describes a specific unit of geological measurement - an epoch. A debate has been ongoing for more than a decade about whether to make that designation official - for the Anthropocene to take over from the Holocene epoch. This debate concluded just a few weeks ago with a definitive “no”.

In this episode of The Case for Conservation Podcast renowned Anthropocene expert Erle Ellis explains what happened to the Anthropocene… and why it doesn’t really matter that it was rejected as an epoch. Erle is an environmental scientist who divides his academic time between the university of Maryland in the US, and Oxford University in the UK. He is a prolific author and public commentator on this and related topics.

Conservation and sustainability scientists are often expected to advise policymakers and other decision-makers. But some of the issues that they are expected to advise on, have broader consensus than others. So, when is it appropriate to advise? When is it appropriate to advocate? When should they simply present all the options or interpretations, and leave it to the decision-makers?

Françoise Cardou is a plant and a community ecologist and postdoctoral fellow at Carlton University in Ottawa, interested in understanding how people and nature affect each other in socio-ecological systems. In a recent paper in Biological Conservation, she and her colleague Mark Vellend discuss how important it is for conservation scientists to know which role is appropriate, to avoid being so-called “stealth advocates”.

Sustainability science, which includes conservation biology and various other environmental studies, is not a “hard science” like physics or mathematics. Nevertheless, one might expect it to be reasonably independent of political affiliation. But is this the case? If not, what is the problem with leaning too far in one political direction, especially if that direction is left and generally considered to be “pro environment”? If it is a problem, what can we do about it?

Örjan Bodin is a sustainability scientist at the Stockholm Resilience Centre at Stockholm University, who has thought a lot about this topic and published a recent paper on it. Örjan is quick to point out that he has not formally studied political polarization. However, with decades of research experience in sustainability science, he provides some compelling reasons why we should pay attention to this overlooked but potentially highly consequential issue.

Capitalism gets a lot of negative press these days, and one of the main arguments against it is the environmental degradation with which it’s associated. But how much is capitalism itself responsible, and how much are people conflating it with associated phenomena? Are the realistic alternatives any better, or should our efforts be focused on reforming this system, which has already done so much for human flourishing?

Russell Galt has many thoughts about the problems with capitalism, but he is also wary of how we go about changing the system. Russell is Head of Policy and Science at Earthwatch Europe, a Partner at the sustainability consultancy, Value-based Work, and Chief Development Officer at Urban Biodiversity Hub. He’s also a friend, upon whom I know I can rely for an honest opinion, and he recently completed an MBA to add to his environmental qualifications. This discussion attempts to touch on various aspects of the arguments for and against capitalism in the context of the environment. The main point is to illustrate the complexities of the issue, rather than to arrive at definitive answers to my questions.
