The Environmental Working Group offers a list of the "Dirty Dozen" fruits and vegetables most likely to be contaminated with pesticides. Also check out their "Clean Fifteen" for the least toxic choices. Carrots anyone?

Bees are famously attracted to flowers by sight and scent, but maybe there's more going on than is widely known. Scientists researching electrical signals suggest flowers may pick up messages from nearby buzzing bees and respond by changing their nectar production.

Ranchers say their cattle, horses and fish are being killed by run-off from farmland fertilizers. They say the biosolids made from human waste contain PFAS, also sometimes called "forever chemicals."

If you ever have the sense food isn't as good as it used to be, you're right. There's been an "alarming" decline in the nutritional value of food over the past 60 years. Reasons include the "shfit from natural farming to chemical farming." Article here from Foods Journal. 

A contest started for fun in the Netherlands also happens to help enhance biodiversity, reduce the harms of climate change and -- says the founder -- boost happiness. It's all about removing paving stones and cities are competing to see which can create the most green spaces. More in this article from the Guardian.

Researchers in the U.S. compared the nutritional differences in food grown using industrial agriculture (with synthetic fertilizers and pesticides) and regenerative agriculture (with soil-friendly practices such as no-till and crop rotation) by pairing 10 farms of each type with each other. The results point to soil-supporting farming if you want healthier food.

Pollution from auto traffic has been linked to numerous health issues including asthma, lung cancer and heart attacks. But less so when roadside vegetation captures some of the soot and fine particles, according to this report from Georgia State University.

Living Green Infrastructure:

Hopeful Strategies for the Future of Urban Living

By David Tracey

In this article, author and Gaia College instructor David Tracey explores how Living Green Infrastructure can help mitigate the impacts of extreme weather events on urban environments. Thanks to integrative nature-based solutions, municipal leaders and citizens alike can feel hopeful about combating the climate crisis. 

Living Green Infrastructure is now a study stream offered through our Diploma in Organic Land Care. 


Even long term climate crisis watchers would have found the news this summer particularly troubling. 

They had to close the Acropolis to prevent tourists from suffering heat stroke in Athens, a city which has also hired Europe's first Chief Heat Officer (CHO). Canada's worst fire season in history led officials from New York to Chicago to issue air quality warnings. In lower South America temperatures reached nearly 40 degrees Celsius during what was supposed to be their winter, a phenomenon climatologist Maximiliano Herrera called one of the "most extreme weather events the world has seen." Even our most reliable temperature regulator to date, the sea, is in peril with the BBC headlining, "Ocean heat record broken, with grim implications for the planet."

Grim yes, but hopeless, certainly not, if enough people commit to the solutions such as Living Green Infrastructure. This innovative approach to city-building takes a holistic, ecological approach to development using nature as a guide. While grey infrastructure channels excess storm water through a system of curbs and gutters and pipes to a treatment plant or large body of water, green infrastructure means adding areas of healthy plants and living soils to absorb stormwater in place. This can not only reduce construction and renewal costs of massive concrete networks, but also improve health and quality of life for human and non-human urban dwellers.


"Grim yes, but hopeless, certainly not, if enough people commit to the solutions such as Living Green Infrastructure."


Living Green Infrastructure (LGI) can go by various names, including Green Infrastructure (GI) and Low Impact Development (LID), but the principle of working with rather than against nature is the same. No matter what scale – from a rain barrel to water the garden around a single home to a conduit of wetlands linking a region, Living Green Infrastructure adds life while softening the harder edges of urban existence. 

Doing it right, naturally, all comes down to the details. As a holistic approach, it requires people with the vision and skills to collaborate with like-minded colleagues across boundaries. Designing the living city our planet needs doesn't mean you must master each part. Someone trained to help living soil ecosystems thrive amid crowded urban conditions may not have the time or resources to become an expert in how city trees grow differently than their forest counterparts. But gaining a fundamental knowledge in the value of the components and how they all fit together is crucial for anyone hoping to join the growing list of those working for a better planet.

Urban designers, planners and engineers, as well as urban growers, educators and anyone else looking to improve our living conditions at home and planet-wide will find a rich source of study materials through Gaia College's course in Living Green Infrastructure. Besides providing a chance to develop the skills and language required to work with Living Green Infrastructure, it may also offer something rare for our challenging times: hope. 

Remember Athens? It too is looking at Living Green Infrastructure to tackle the climate emergency, including a plan to revive an ancient Roman underground viaduct to water parks and create more green and blue spaces. Another example of a nature-based solution, a good idea whose time seems to have come again.
