Biochar can store carbon and improve soil health, but recent analysis warns against overhyping its potential.
The Wasteland Nomad is built from biochar and seeds of indigenous plants, which are both biodegradable materials. Biochar works like a sponge inside the soil, as it holds water, gives microbes a surface to live on, and locks carbon into the ground instead of letting it escape into the air.
Around a third of UK gardeners use pesticides, and our studies found that house sparrow numbers, for example, were nearly 40% lower in gardens where the pesticide metaldehyde was used. By reducing pesticide use, you can actively encourage birds back into your outdoor spaces, as they rely on invertebrates such as slugs and snails as natural prey.
Wildfires have become an ever bigger problem in Canada. The 2018 wildfires were the biggest in British Columbia's history, but this record was broken in 2021, and then again in 2023, when fires consumed an area three times the size of the Canadian province of Nova Scotia and the smoke travelled as far as New York City.
Starting plants from seed extends your relationship with the garden, gives you more control over seed sourcing, and saves real money compared to buying nursery starts, sometimes as much as 90% per plant.
Climate breakdown is occurring more rapidly with the heating rate almost doubling, according to research that excludes the effect of natural factors behind the latest scorching temperatures. It found global heating accelerated from a steady rate of less than 0.2C per decade between 1970 and 2015 to about 0.35C per decade over the past 10 years.
For Staller, foraging is a "precious" and "simple" activity that one can do to connect with nature. They can experience a sense of mindfulness from gathering together, looking for food and then cooking the bounty, she said. "We are returning to the most basic part of being a human, which is eating food and celebrating it," Staller said. "It's a lost artform."
On this episode: Lucy Lopez, Elizabeth Newcamp, and Zak Rosen get into a listener's question about whether or not to gift a gaming counsel to their college kid. They bought the gift when the kid was doing well in school, but now they're struggling again. Should that matter? But first, they share their latest triumphs and fails. Elizabeth is in her Worm Era and explains the wonders of vermicomposting.
In Indra's Net of pearls and jewels, every gem reflects every other, a shimmering image of interdependence. This ancient Vedic metaphor for connection across the cosmos also illuminates what the environmental philosopher Glenn Albrecht first proposed in 2014as 'theSymbiocene': the era after the Anthropocene, in which human technologies take their cues from living systems and work in partnership rather than through dominance.
A passerby discovers it first - and lets out a piercing call. Within seconds, everyone in earshot rushes to the scene. It's mayhem... or so it seems. Crows are intelligent, and super chatty. They watch out for one another within tight-knit groups. As adults it's pretty rare for crows to be killed. So when one dies the others notice. Are they just scared? Or is something deeper going on.
Last week, I was making my morning coffee-you know, the complicated order I'm too embarrassed to say out loud at coffee shops-when I noticed the pile of used grounds in my filter. For years, I'd been tossing these straight into the trash without a second thought. But then I remembered something my grandmother wrote in one of her letters years ago: "The garden teaches us that nothing is truly waste."
The term "soil fatigue" or exhaustion refers to the condition that soil profiles take on when they've been heavily monocropped and untended. This soil is devoid of the microbial content that offers plants bioavailable food. It lacks the fungal and bacterial organisms that interact with plant nutrients.
Signs of ageing accelerated when fish were exposed to the chemicals, according to the study, which could have implications for other organisms. Chemical safety regulations tend to focus on short-term exposure to high doses of pesticides and other chemicals, but the study focused on long-term exposure. Low doses of pesticides are widespread in the environment, so their effects should be studied and understood, the authors said.
As concepts such as "regenerative" and "biodynamic" continue to enter the mainstream coffee lexicon, scientists continue to literally dig into the soil to give them meaning. A recent peer-reviewed study from India's Western Ghats argues that one of the clearest signals of healthy, sustainable coffee farms lies in the ground itself, with organic coffee soils performing better than soils from conventional farms treated with synthetic inputs.
When the category-5 storm Hurricane Melissa struck Jamaica in October, its path crossed communities that had varying levels of preparedness. Many with maintained coastal protections, upgraded drainage and reliable early-warning systems had power and water restored in days. Others were immobilized for weeks.
The world spends 30 times more money destroying nature than protecting it. That's according to a new report from the United Nations Environment Programme (UNEP) that exposes a massive gulf between so-called "harmful investments" and financing that promotes nature preservation. The global environment agency's latest "State of Finance for Nature" (SNF) report is calling to phase out the US$7.3 trillion (6.2 trillion) in global investments that damage nature including into high-emissions energy infrastructure and manufacturing, for example.
