The question of how intelligent plants and fungi are has been increasingly explored by scientists, as they have delved into the capability of these lifeforms to perceive and communicate with each other and the outside world.

A new study has found that fungi can not only perceive, but learn, have memories, solve problems and make decisions.

“You’d be surprised at just how much fungi are capable of,” said Yu Fukasawa, as assistant professor in the graduate school of agricultural science at Tohoku University, in a press release from Tohoku University. “They have memories, they learn, and they can make decisions. Quite frankly, the differences in how they solve problems compared to humans is mind-blowing.”

When you see mushrooms growing on the surface of soil, the small umbrella-like caps are really the fruiting bodies of an expansive underground mycelium below. The mycelium is an intricate and complex fungal network germinated and formed by spores. This subterranean web of long, spidery threads spreads underground like roots and is similar to the brain’s neural connections.

In the study, the researchers looked at how a mycelial network growing on decaying wood responded to two distinct situations: wood blocks arranged in a cross arrangement versus in a circle.

If the fungi did not have decision-making skills, they would spread out from the center without being affected by the placement of the blocks. However, this is not what happened.

“For the cross arrangement, the degree of connection was greater in the outermost four blocks. It was hypothesized that this was because the outermost blocks can serve as ‘outposts’ for the mycelial network to embark in foraging expeditions, therefore more dense connections were required,” the press release said. “In the circle arrangement, the degree of connection was the same at any given block. However, the dead center of the circle remained clear. It was proposed that the mycelial network did not see a benefit in overextending itself in an already well-populated area.”

But how were the fungi in the study able to perceive the blocks?

“Probably through touch and ‘taste,’ Fukasawa told EcoWatch in an email. “While contact certainly influences mycelial behavior, they likely need to ‘taste’ the wood blocks to recognize them as a resource. This ‘tasting’ could involve secreting enzymes to break down the wood surface (e.g., cellulose) and absorb the resulting low-molecular sugars (e.g., glucose). Additionally, fungi may also ‘smell’ the wood, meaning they can detect volatile chemicals released, which might either promote or inhibit mycelial growth.”

Fukasawa said the question of whether fungi have memories is “a poorly explored but fascinating topic.”

“There may be several mechanisms of fungal memory, with the longevity of the memory potentially depending on the specific mechanism. One possibility is cellular-level memory, based on organelle dynamics such as the cytoskeleton and aggregates of small vesicles (called Spitzenkörper), which may produce relatively short-term memory,” Fukasawa told EcoWatch. “Studies suggest that memory of growth direction at the hyphal tip could be maintained for at least the length of a 100 µm hyphal growth. However, if memory is stored through other mechanisms, such as epigenetic changes in cellular activity, it could last longer.”

The findings suggest that the network of mycelia could communicate information regarding its surroundings throughout the whole fungal network. The mycelium was also able to alter its direction of growth based on the shape of the blocks.

“Our comprehension of the mysterious world of fungi is limited, especially when compared to our knowledge of plants and animals. This research will help us better understand how biotic ecosystems function and how different types of cognition evolved in organisms,” the press release said.

Fukasawa told EcoWatch that, not only are fungi important to ecosystems, they also help mitigate climate change.

“The main known functions of fungi in ecosystems are categorized as decomposers, symbionts, and pathogens. These functions often overlap (i.e., a single fungal species can perform more than one function), and all are important to ecosystem processes. However, when we focus on mitigating climate change, their role as decomposers is undoubtedly the most significant,” Fukasawa explained. “Decomposer fungi break down plant carbon polymers into low-molecular-weight carbon compounds for energy, eventually releasing CO2 through respiration. Thus, decomposition is a process that releases CO2 into the atmosphere.”

Fukasawa said there are two different kinds of wood decomposition: white rot and brown rot. With white rot, the wood’s cellulose and lignin are broken down, and with brown rot, just the cellulose is broken down, while the lignin remains intact.

“These different types of decomposition can affect the amount of CO2 released during the process. Additionally, recent studies show that a diverse decomposer fungal community actually slows down wood decomposition, suggesting that higher diversity among decomposer fungi may reduce CO2 emissions from forest ecosystems,” Fukasawa told EcoWatch.

What can people do to better support fungal networks?

“I believe forest fragmentation is a significant issue. Networks of some fungi can spread over areas larger than 900 hectares across the forest floor. In such cases, forest fragmentation directly disrupts fungal networks,” Fukasawa said. “While fungi can spread through airborne spores, maintaining direct connections via mycelial networks is also crucial. Similar to plants and animals, creating green corridors between fragmented forests could help support fungal networks. This is important because fungal mycelial networks can transport a variety of materials and information, which may help improve locally degraded environments and enhance the overall functioning of the ecosystem.”

The study, “Spatial resource arrangement influences both network structures and activity of fungal mycelia: A form of pattern recognition?” was published in the journal Fungal Ecology.

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.”
