The 3,100km concrete wall Donald Trump plans to build along the US-Mexico border would be a disaster for the border zone's ecosystems, writes Shonil Bhagwat. Among the species at risk: ocelots, bears, Bighorn sheep, the US's last wild jaguars facing genetic isolation north of the border, and the Bald eagle, the US's national bird.
At what point are technologies so complex, uncertain, or unmanageable as to be beyond regulation? The question is key to human and ecological health, writes Jonatham Latham. But instead of learning from successful approaches, such as aviation safety, we are throwing the lessons away when faced with truly complex problems - like chemicals, GMOs, and now 'gene drives'.
Removing the natural habitat of Hazel Dormice - one of the UK's most endangered species - is further threatening their existence says a new report from Manchester Metropolitan University. LAURA BRIGGS reports
A study of GMO cotton varieties shows they disrupt an important beneficial soil fungus, writes Eva Sirinathsinghji, apparently due to the Bt insecticide they are engineered to express. Disruption caused by the transgenic cotton to mycorrhizal fungi, and the wider soil ecosystem, may underlie the low yields and poor pest resistance now endemic among Bt GM crops.
Conventional economic analyses of trade tend only to discern the flows of money, writes NICK MEYNEN. But by also considering biophysical metrics - such as material and energy flows, and embodied water and land - ecological economists can identify the asymmetric flows of resources obscured by the apparent reciprocity of market prices.
To embrace the Earth as truly alive is a step too far even for many committed environmentalists, writes Charles Eisenstein: worried that others may perceive us as unscientific, childish, woolly-headed and ridiculous. But it's a step we must take: in refusing to recognise the living Gaia that is both our creator and our home, we accept and perpetuate the philosophy of her destroyers.
In the first of our new WITNESS series of blogs, food anthropology researcher YVONNE ADEBOLA suggests a 'One Health' approach to childhood obesity which recognises the ecological impact of modern food systems on the environment and on our collective health and wellbeing
A 30-year decline in toad populations recorded by volunteers, shows the need to rebuild vital 'green infrastructure' across both the wider countryside and urban areas, writes Oliver Tickell: reversing habitat fragmentation, digging out ponds and ditches, and leaving ample unkempt areas for cover and hibernation.
The EU is already paying farmers and landowners for creating and maintaining valuable habitats, write Dominic Hogg & Luke Dale-Harris. But could the UK do better by creating markets in 'ecosystem services' that would put financial value on clean water, key wildlife habitats, endangered species and precious landscapes?
Ecosystems don't collapse a little at a time, writes JAMES DYKE, but all of a sudden. So how can we see the danger signs and act in time to save them? A new study of eutrophic lakes shows that the answer lies, not in easily-measured nutrient levels, but from a more subtle understanding of the lakes' shifting ecology and types of species: keystones, weeds and canaries.
They said it would never work but time has proved those critics wrong. As the inspirational and pioneering Devon centre that combines ecology and spiritual learning celebrates its 25th anniversary, founder and Editor Emeritus of Resurgence & Ecologist, SATISH KUMAR, describes the flourishing of this remarkable and pioneering place of learning
The disappearance of a satellite-tagged hen harrier on a Scottish grouse moor and the loss of eight Golden eagles in five years provide the latest evidence for a ban on driven grouse-shooting, writes EDUARDO GONCALVES. But birds of prey are only the most high-profile victims of a cruel and ecologically destructive industry.
The National Farmers Union has been issuing dire warnings that if UK taxpayers do not keep on paying landowners billions of pounds of annual subsidies after Brexit, many will simply give up farming altogether. So, asks CHRISTOPHER SANDOM, how would our countryside change if they followed through on that threat? (Or was it a promise?)
Calls for better protection of the UK's ancient woodlands are being made by environmental groups due to a loophole in the National Planning Policy Framework (NPPF), last revised in 2012. LAURA BRIGGS reports
Although flowing water is fundamental to river ecosystems, temporary streams are distinctive landscape features that support surprisingly diverse communities, writes Rachel Stubbington. However, the biodiversity of these dynamic ecosystems needs greater recognition and protection.
One of our New Voices is the UK-base environmental painter and activist Gary Cook who will be writing for us about the visual arts. As an introduction to his work, the committed conservationist explains how his extraordinarily powerful 'info-canvases' educate people about the threats to wildlife and the need for immediate action to protect our most endangered species for future generations.
Plastic is ubiquitous around the world's oceans, writes Lesley Henderson, but although it's visible from space, it can be surprisingly elusive in the water - as she heard from Jo Ruxton, producer of the investigative documentary 'A Plastic Ocean'. Solutions to this growing hazard have also proved elusive to date, hence the film's strong focus on action: educational, cultural and legal.
Those opposed to the mass release of GM crops and foods inadequately tested for health and ecological safety are routinely accused of being anti-science, writes Elizabeth Henderson. But it's the GM corporations and their academic allies that are suppressing scientific research, and organic farmers that are building alliances with independent scientists for a future of safe, healthy food.
A future of green abundance for all is possible, writes Glen Barry. Instead we are mired in the destruction of the Earth's vital ecosystems, divided by obscene wealth and shameful poverty, and pitted against each other in genocidal wars over energy, resources and global dominance. To make that alternative a living reality, we must shed our fears and come together in common purpose.
Where does the Green Party go now? Last week's uninspiring election results show that Jeremy Corbyn's Labour poses a serious challenge to us Greens, who can no longer succeed by being merely left wing. We must fulfil our own destiny, representing a distinct, authentic ecological strand in politics, making the case for living as if we only had one planet - as is in fact the case.
A recent scientific study found the same long-chain omega-3 oils that are engineered into a new GM Camelina oilseed variety make butterflies grow up with deformed wings, writes Claire Robinson. Attempts by the 'pro-science' non-scientist Mark Lynas to discredit the study are a mixture of ignorance, research failures, 'straw man' arguments and outright errors.
The quiet desperation of declining towns and cities across America's West is understandable, writes George Wuerthner. Of course people dream of the 'good old days' when there were wild prairies to be grazed, forests to be felled and oil wells to be sunk - and try to bring them back. But in so doing they neglect and abuse their real and enduring wealth: nature, landscape and wildlife.
A new study shows that the market-leading Roundup herbicide kills soil microbiota at concentrations 50 times lower than used in agriculture, writes Claire Robinson. The findings raise serious new concerns about the environmental impacts of glyphosate herbicides.
Britain's ash woods are under threat from a fast-spreading 'dieback' disease, write Steve Woodward and Eric Boa. With 3% of ash trees resistant to the fungus, the species should just be able to survive. But now scientists fear the arrival of the Emerald ash borer beetle, already infesting forests in the US and mainland Europe. Could the two combine to push our ash trees into extinction?
