A Conversation With Shahid Naeem, Biosustainability Scientist
The world we are leaving our children and their children is not the one we inherited; climate is changing, new diseases are emerging, exotic species are spreading, soil is eroding, pollution is occurring at global scales, and food, energy, and water security are plummeting. The economic debt our children will inherit that garners so much attention is rather mundane by comparison. Shahid Naeem is a scientist, however, who feels that environmental solutions can be found by conserving biological diversity; a different view of why conservation matters.
Usually, plants and animals are seen as innocent bystanders suffering in the face of global change, an unfortunate but necessary outcome of economic growth. Conservation biologists therefore focus primarily on finding ways to help out and protect these millions of species that are at risk of going extinct as the environment changes. But what if saving species is actually a way to stop erosion, clean up air and water, stabilize the climate, and much more? Naeem is one of the founders of a more modern view of biodiversity as the engine of our environment, not merely collateral damage of an increasingly unstable and unsustainable environment. Conserving biodiversity is not just a goal in and of itself, but a valuable way for solving environmental problems — save the whales not just because we love them, but because they make our marine ecosystems more productive and more stable which, in turn, makes our lives better.
Here, Naeem discusses what it would be like if, all of a sudden, breathable air, potable water, equitable climate, fertile soil, pollination, and other products and services we’ve grown accustomed to were considered part of our economies; the radical shift away from traditional natural science that emphasized the role of evolution in understanding the diversity of life on Earth; and why we desperately need to finally get away from the same primitive carbon-based energy system used by cavemen.
What do you say when people ask you, “What do you do?”
I used to say I’m an ecologist, which is in fact accurate, but I noticed that people immediately assumed I was either an anti commerce tree-hugging pantheist liberal who would have us return to loin cloths and feed off insects and berries or a passionate lover of animals who would risk frostbite or death to radio collar a snow leopard in the Himalayas. So now I say I’m a professor knowing that will peg me as an academic and that immediately leads to the follow up question of, “so what is it you study?” It’s then that I say I study what happens to nature when it is dismantled. Really interesting conversations always follow.
What new idea or innovation is having the most significant impact on the sustainability of our world?
Over the last few years, there has been a radical shift away from traditional natural science that emphasized the role of evolution in understanding the diversity of life on Earth to trying to understand what role such a diversity of species play in environmental processes. It’s an admittedly utilitarian view of species — what is their environmental function rather than their origin? — and that does not sit well with many lovers of nature. This new emphasis is called “trait-based ecology” because it focuses on the traits of species, or what features of species tell us how they influence or respond to environmental change. Traditionally, the vast majority of work on species concerned how species evolve and figuring out where they are on the evolutionary tree of life. These approaches, such as phylogenetics, systematics, or taxonomy, are important fields in the natural sciences, but they are not terribly informative about why species matter. Once you start looking at what species actually do — are they pollinators, do they remove nitrogen from the atmosphere, do they stabilize shorelines, do they degrade organic pollutants? — suddenly all those species start to matter. Once we have a comprehensive list of species, their traits, their functions, and their connections to one another, we might actually begin to build a realistic blueprint of the biosphere and how it works. With the advent of the Internet and increasingly more powerful computers, we can embark on this greatest of all quests — to build a working model of the Biosphere based on its species. Then, and only then, can we figure out how to achieve environmental sustainability. I like to call this view, “biosustainability,” a contraction of “biologically based sustainability.”
What’s something that most people just don’t understand about your area of expertise?
Two interrelated terms or concepts critical to my area are the devil to grasp. Even experts in our field sometimes get them wrong. The first is “biodiversity,” which is almost always thought of as a collection of wondrous beasts and beautiful flowers. The second is “ecosystem,” which is generally thought of as a wild place like a forest or prairie. In fact, biodiversity refers to all the elements of diversity of life on Earth, whether it is genetic, taxonomic, functional, structural, spatial, or temporal diversity, and it includes all living things, including the microbes, not just the plants and animals. Similarly, an ecosystem is also a complex term, referring to a system that produces and consumes biofuels (plants or algae) while cycling inorganic matter, such as oxygen, carbon dioxide, and water, to organic matter, such as carbohydrates, proteins, and nucleic acids like DNA, and back again. To make things worse, since you can never have biodiversity outside an ecosystem and an ecosystem always has biodiversity in it, each term doesn’t make sense without reference to the other. I have an easier time explaining quantum mechanics and multivariate statistics than explaining what biodiversity and ecosystems are. Yet, to understand the fundamentals of living sustainably, one has to have a firm grasp of both biodiversity and ecosystems. By Nicholas Jackson, Atlantic
