The Case for Conservation Podcast

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....

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 pollina...

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....

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 Car...

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 conside...

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 f...

As a result of our success as a species, we have been ushering other species toward extinction for thousands of years. The pace of those extinctions increased markedly with the growth of the world’s population since the Industrial Revolution. But we are now within reach of the “Jurassic Park” -type fantasy of being able to reverse extinctions - to bring back species from the dead. On the other han...

Many conservation managers and scientists may not be aware that there is a single, common set of global biodiversity targets that inform national conservation strategy in almost every country in the world. These 23 targets are the main part of the “Kunming-Montreal Global Biodiversity Framework”, or GBF. The GBF was agreed on by Parties to the Convention on Biological Diversity (CBD) in late 2022,...

This month’s episode is about activism and science communication, and whether or not they should be combined. There are obvious tensions here because science is meant to be as objective as possible, while activism is characteristically impulsive and political. And, of course, there can be activists on both sides of a debate. There can also be incomplete or poorly reported science, upon which that...

Climate change gets a lot more attention and funding than biodiversity. But, as conservation organizations are keen to point out, climate and biodiversity are intimately linked and there is, therefore, a good argument for addressing them side by side. Part of that argument is that conserving biodiversity is good for the climate. But an even more obvious link is that climate affects biodiversity. H...

In decades past, conservation was notorious for ignoring other development goals. These days, its focus has expanded to consider those other goals, including the prevention of poverty and hunger. In fact, there seems to be a tendency to assume that conservation is always compatible with them, and necessary to achieve them. There is certainly truth in that, but are we talking enough about the inevi...

Species. We take them for granted as the main currency of biodiversity. But how many of us really know what species are? And do we attach too much importance to them, especially in the context of conservation? Over centuries, taxonomists have categorized and re-categorized life forms and graphically presented their relatedness in the form of a so-called ”tree of life”. The trunk of the tree is com...

Historically, the oceans have received too little attention in discussions about the environment and biodiversity. On the topic of biodiversity loss in particular, however, one marine system has attracted almost as much attention as the rainforests: coral reefs. Coral reefs have even been described as the rainforests of the sea, thanks to their remarkably high levels of biodiversity. Recently, Uni...

ESG is the latest buzzword in business & biodiversity circles, but it’s not actually new - only newly popular. And it’s one among many terms and acronyms in this field, which may be familiar but are often poorly understood - ESG stands for “environmental, social and governance” investing criteria. Understanding concepts like ESG is consequential because their success relies largely on convinci...

There is a tendency in societies to adhere to conventional wisdom. We resist challenges to consensus views, and may even dismiss those who do challenge them as conspiracy theorists... which they sometimes are. But perhaps we take that idea too far sometimes. Perhaps we underestimate the importance of having the freedom to challenge orthodoxy. We live in an age in which more people than ever before...

You may have heard of the concept of “biodiversity risk”, especially in the context of business. It has become increasingly widely used in recent years and the Task Force on Nature-related Financial Disclosures (TNFD) is a recent development that has done a lot to popularize the concept. But what exactly is biodiversity risk and, for that matter, what is TNFD? Why has this topic been gathering so...

Wherever conservation takes place, at whatever scale, and in whatever form, there’s a good chance that it is somehow affected by the decisions taken under multilateral environmental agreements, or “MEAs”. These agreements, such as the Convention on Biological Diversity, are made between multiple countries - sometimes including almost all of the world's nations - with the aim of addressing one...

In days gone by development (of cities, infrastructure, agriculture, etc.) happened without regard for the environment. And it was really the devastating effects of unimpeded development that led to the establishment and early growth of the environmental movement, broadly speaking. We have become much more efficient at using land and other resources, but development remains inevitable. In theory,...

After decades of struggling for recognition, environmental issues, including biodiversity conservation, have exploded onto the global scene in recent years. This is incredibly encouraging and gratifying, but are we sufficiently aware of the risks that come with such vastly increased public support? How much is politics influencing the public discourse on the environment? Are we paying enough atten...

This month, for the first time, I am the interviewee rather than the interviewer. This episode was recorded for BioScience Talks , the podcast of the journal BioScience , which recently published an article that I co-authored. The article is about science and media communication around Covid-19 and, in particular, the way that some of the scientific literature, and much of the media, have portraye...

Covid-19 has, probably more than anything, ever, made science communication a matter of public interest. A couple of weeks before recording this episode, the journal BioScience published an article that I co-authored, which takes a critical look at one aspect of science messaging - the way it has portrayed the relationship between land change and  infectious disease risk. That paper will actually...

Cities - even the greenest of them - replace nature with glass, concrete and asphalt. And their footprint extends far beyond their boundaries to provide for the needs of the thousands, millions, or ten of millions of people concentrated within them. They are home to most of the people on Earth and are the sources of most pollution. But it seems cities are also an inevitable result of the developme...

Few technologies are viewed with as much suspicion as genetic modification. Genetically modified organisms (GMOs) are banned in several parts of the world; an entire protocol under the Convention on Biological Diversity (CBD) is dedicated to controlling their effects on biodiversity; and national and international agreements and regulations tightly legislate their use across a broad range of appli...

This episode is about environmental alarmism. Alarmism means exaggerating danger and thereby causing needless worry or panic. These days the media is flooded with proclamations and predictions of ecological catastrophe. There is no doubt that our environmental challenges are many, and huge, and they certainly do present dangers. But are they being seen in the context of broader developmental chall...
