More than a third of animals on Earth are herbivores, but since plants don’t have a lot of calories it can be hard for grazers to eat enough to meet their energy needs. To add to the problem, climate change is lowering the nutritional value of certain foods that these plant eaters rely on.

Fossil fuel emissions produced by humans are causing levels of atmospheric carbon dioxide to rise, pushing up temperatures worldwide. This is causing plants to grow faster in ecosystems across the globe, research biologist Ellen Welti with the Smithsonian Institution’s Great Plains Science Program wrote in The Conversation.

“Some studies suggest that this ‘greening of the Earth’ could partially offset rising greenhouse gas emissions by storing more carbon in plants. However, there’s a trade-off: These fast-tracked plants can contain fewer nutrients per bite,” Welti wrote in The Conversation.

Welti and colleagues looked at the ways in which nutrient dilution might impact species throughout the food web. They focused on the responses of plant-feeding populations, from giant pandas to grasshoppers.

“When we look at future climate change, it’s not the same as the current hot years that we experience,” said Alex Ruane, co-director of NASA’s Goddard Institute for Space Studies’ Climate Impacts Group. “If we were to find a location and look at a hot year that was recently experienced, it would likely have been a heat wave that would have raised the overall temperature. Climate change is different. Climate change is every day, a little bit more and more. When those heat waves come [in the future], they’re just a little bit more intense or extreme, and that has a different physiological impact [on plants].”

Welti said changes in plants’ long-term nutritional value could be one underappreciated cause of falling animal populations.

“These changes in plants aren’t visually evident, like rising seas. Nor are they sudden and imminent, like hurricanes or heat waves. But they can have important impacts over time,” Welti said in The Conversation. “Plant-eating animals may need more time to find and consume food if their usual meal becomes less nutritious, exposing themselves to greater risks from predators and other stresses in the process. Reduced nutritional values can also make animals less fit, reducing their ability to grow, reproduce and survive.”

The nutrient value of livestock feed has also been declining. It is often difficult for cattle — who spend much of their time eating — to find enough protein, as protein concentrations are falling across rangelands all over the planet, threatening livestock and ranchers.

Nutrition dilution also affects wild species like some insects.

“Insects are essential members of the web of life that pollinate many flowering plants, serve as a food source for birds and animals, and perform other important ecological services. Around the world, many insect species are declining in developed areas, where their habitat has been converted to farms or cities, as well as in natural areas,” Welti explained. “Many insects are plant feeders that are likely to be affected by reduced plant nutritional value. Experiments have found that when carbon dioxide levels increase, insect populations decline, at least partly due to lower-quality food supplies.”

Leaf-chewing insect species like caterpillars and grasshoppers suffer the most negative impacts, from smaller body sizes to reduced reproduction.

Other insects like cicadas and aphids could benefit from carbon-rich plants.

“Certain types of plant-feeding animals are likely to face greater declines because they need higher-quality food. Rodents, rabbits, koalas, horses, rhinoceroses and elephants are all hind-gut fermenters – animals that have simple, single-chambered stomachs and rely on microbes in their intestines to extract nutrients from high-fiber food,” Welti added.

Welti said more research will be necessary to understand the role of nutrient dilution in the declines of individual species.

“Over the longer term, it will be important to understand how nutrient dilution is altering entire food webs, including shifts in plant species and traits, effects on other animal groups such as predators, and changes in species interactions. Changes in plant nutritional value as a result of rising carbon dioxide levels could have far-reaching impacts throughout ecosystems worldwide,” Welti said.

10 Books to Counter Consumerism

Published

May 20, 2026

Alice Rush

We are constantly bombarded by messages that tell us we need more stuff to be happy. The average American household contains around 300,000 items. The average home size has roughly tripled since the 1950s, and we still rent self-storage units by the millions to hold the overflow.

If you are rethinking your relationship to consumer culture – whether by choice or necessity – we’ve rounded up a list of books to make breaking up with consumerism and easier to understand which of our purchases are really necessary.

(Amazon links are provided for convenience. Your local library and independent bookstore are excellent first stops.)

Empire of Things

by Frank Trentmann

Trentmann’s sweeping 2016 history follows material culture from late Ming China and Renaissance Italy through to today’s global supply chains. He shows that consumerism is not a recent American export but a centuries-long international phenomenon, one that has reshaped households, cities, and the planet.

Empire of Things is dense but never preachy, and it gives readers the long view needed to understand what we are actually pushing back against.

No Logo – 10th Anniversary Edition

by Naomi Klein

No Logo was a movement manifesto when it appeared in 1999, and its dissection of branding, sweatshop labor, and corporate cultural takeover reads as prescient now that nearly every screen on earth is an ad surface. To take the next step, pair this read with Klein’s more recent argument about capitalism and ecological collapse, How To Change Everything.

The Conscious Closet

by Elizabeth L. Cline

Cline first exposed the human and environmental costs of fast fashion in Overdressed (2012). The Conscious Closet is the practical follow-up: how to clean out, repair, swap, and rebuild a wardrobe without funding the industry that produces an estimated 92 million tons of textile waste each year. It is the most actionable book on this list for anyone with a closet.

The Myths of Happiness

by Sonja Lyubomirsky

Psychology professor Sonja Lyubomirsky brings the receipts. In The Myths of Happiness, she walks through decades of research showing that material milestones — the raise, the upgrade, the bigger house — produce short bursts of satisfaction that fade quickly. What actually sustains wellbeing is rarely for sale. A clarifying read for anyone tempted to outshop their way to contentment.

How to Do Nothing: Resisting the Attention Economy

by Jenny Odell

Waste is coming for our minds, too. Odell argues that our scarcest resource is attention — and that the platforms we use have turned it into the raw material of a trillion-dollar industry. How to Do Nothing is not a digital-detox manual; it is a case for reclaiming attention as a political act, with consequences for everything from bird-watching to civic life. More relevant in 2026 than when it was published in 2019.

Less Is More: How Degrowth Will Save the World

by Jason Hickel

Economic anthropologist Jason Hickel makes the case that endless GDP growth is incompatible with a livable planet, and that “green growth” is mostly a marketing exercise. Less Is More (2020) traces 500 years of capitalism and lays out what a degrowth economy could actually look like — one organized around human and ecological flourishing rather than perpetual expansion. The book has helped move degrowth from the margins of academia into the mainstream of the climate debate.

The Day the World Stops Shopping

by J.B. MacKinnon

Journalist J.B. MacKinnon designed The Day the World Stops Shopping (2021) as a thought experiment — what would happen if global consumption dropped by 25%? — and then watched the pandemic run a version of the experiment in real time. He travels from Namibian hunter-gatherer communities to American big-box retail, talking to economists, ecologists, and CEOs. The result is one of the most readable accounts of why we shop, why we cannot easily stop, and what we would gain if we did.

Consumed: The Need for Collective Change

by Aja Barber

Writer and consultant Aja Barber connects fashion, colonialism, and climate in Consumed (2021), a debut that has become a touchstone for the ethical fashion conversation. Where Cline writes as a practitioner, Barber writes as a systems critic, tracing the textile trade’s roots in slavery and racial inequality and asking readers to confront why we fill emotional gaps with purchases. Pointed, generous, and built to be read in two sittings.

Wasteland: The Secret World of Waste and the Urgent Search for a Cleaner Future

by Oliver Franklin-Wallis

If consumerism is the input, waste is the output we work hardest not to see. Award-winning journalist Oliver Franklin-Wallis follows that output across continents in Wasteland (2023) — from New Delhi’s landfills and Ghana’s secondhand clothing markets to nuclear storage sites and the corporate origins of curbside recycling. Named a Best Book of 2023 by The New Yorker, The Guardian, and Kirkus, it is essential reading for anyone who has ever wondered where “away” actually goes.

Fixation: How to Have Stuff Without Breaking the Planet

by Sandra Goldmark

Sandra Goldmark runs a pop-up repair shop in New York and serves as director of sustainability at Barnard College. Fixation (2020) is her plainspoken case for getting things fixed instead of replaced, and for building a circular economy where good design, reuse, and repair are the default. Her five-rule formula — borrowed in spirit from Michael Pollan — is the most quotable advice on this list: “Have good stuff. Not too much. Mostly reclaimed. Care for it. Pass it on.”

What You Can Do

Reading is a start, not a finish. A few next steps:

Start at the library. Most of these titles are available through WorldCat or your local branch. Borrowing keeps a book in circulation and out of a landfill.
Audit one category of stuff before adding to it. Pick clothes, kitchenware, or electronics. Inventory what you already own before the next purchase. Most of us own more than we remember.
Find a repair option in your community. Take the time to locate repair, reuse, and donation outlets near you before tossing anything broken.
Support right-to-repair policy. Several U.S. states have passed right-to-repair laws since 2023; the rest are weighing them. Individual purchasing choices matter more when manufacturers are required to make repair possible.
Read one of these books and talk about it. Anti-consumption is harder alone. Book clubs, mutual-aid groups, and faith communities have all become surprising hubs for this work.

Best of Sustainability In Your Ear: EarthX CEO Peter Simek on Cultivating Bipartisan Climate Strategies

For 15 years, the Dallas-based climate conference the EarthX conference has created space where fossil fuel executives and environmental activists, Republican appropriations chairs and Democratic climate hawks, find common ground. The organization targets three core stakeholders: the corporate world, policymakers, and investors seeking startups where environmental solutions are baked into the bottom line. Peter Simek, EarthX’s CEO, explains how reframing climate action around shared values—stewardship, economic opportunity, and love of the land—unlocks support that crisis messaging alone cannot reach.

The doom story doesn’t sell, Simek explained. “We’re not motivated as a species by doomsday language. It puts people in fight-or-flight mode.” He points out how climate became an identity issue, tangled up in culture-war debates over hamburgers and gas-powered trucks, when the real conversation should center on clean air, clean water, and protecting the places we love. “The EPA and the Clean Air and Clean Water Act were passed during the Nixon administration,” he notes. “There are ways to message this that appeals across lines.”

Peter Simek, CEO of EarthX, is our guest on *Sustainability In Your Ear*.

Simek bets heavily on bottom-up action as EarthX works to build bridges. States, cities, and private capital often move faster than federal mandates, he argues, and they’re harder to reverse with a single executive order. Texas leads the nation in renewable energy deployment because wind and solar make bottom-line sense. “Even as there’s a policy turn against it, there’s still the driving reality that solar and wind are viable energy sources,” he says. A new event in 2026, the EarthX Institute, will focus on two policy priorities: nuclear energy, where bipartisan consensus is growing, and urban biodiversity.

Whether conversations at forums like EarthX translate into policy velocity that matches the pace of climate impacts remains to be seen. Simek says he stays focused on tracking downstream results, specifically the investments funded, the coalitions built, and the policies incubated from the local level up. “It’s about finding those ways in which there’s common sense, common ground, common values,” he says. “Elements to talking about nature and the environment that no one can really disagree with.”
