Campaigners who dared confront the might of the US's nuclear weapons establishment, in the process revealing the chronic insecurity of its facilities, are paying a heavy price, writes Michael Edwards. But their strength, serenity and joy in the face of brutal injustice brings hope to the world for a just and peaceful future.
Lewis Pugh has completed long-distance swims in the 'seven seas' to promote his dream of a peaceful world of well-managed Marine Protected Areas, abundant oceans teeming with fish, turtles, whales, sea-birds and sharks. His shocking experiences in the water make that dream more urgent and compelling than ever.
Natural gas is widely touted as a 'green fuel'. But as Paul Thacker found in Colorado, fracking's national 'ground zero', it's anything but. Lives and health are being ruined by pollution from taxpayer-subsidized gas wells, flaring and refining plants, while property values collapse. Now a mass of environmental refugees are fleeing the ravaged state.
Good food is an essential ingredient at Schumacher College, writes Julia Ponsonby, made with love using fresh, wholesome ingredients many of which have traveled no further than the vegetable garden. No less important, the sense of companionship, learning, fun and frequent hilarity that permeates the building - and the kitchen in particular.
Two innovative renewable energy projects are moving forward in Scotland: Britain's first tidal power array, and the world's first deployment of two-bladed wind offshore turbines. The experimental technologies are hoped to achieve significant cost savings and unlock a huge offshore energy resource.
Liberal environmentalism represents a dangerous delusion, writes Scott Parkin - that 'playing nice' with Earth-destroying corporations and politicians can yield results worth having. Radical change on climate will only result from bold, confrontational direct actions against the fossil fuel industries and their apologists.
São Paulo, South America's biggest city, is suffering its worst drought in over a century, writes Jan Rocha, with rivers and reservoirs running dry. But the state's politicians are seeking re-election. And for them, it's as if nothing is happening - never mind that water and power cuts affecting millions are looking inevitable.
We know that Australia's dry bush has co-evolved with fire, so that means regular planned burning is a good thing? Up to a point ... some increasingly rare species depend on 'old growth' bush up to 100 years old, and over-frequent burning is putting them under long-term threat.
Roads are responsible for massive environmental damage around the world, writes Bill Laurance - yet they also bring huge benefits. His solution? A new atlas that shows where the 'goods' of roads outweigh the 'bads', so that developing countries can harness the prosperity new roads can bring, without the destruction.
It was a great story, writes Andrew Lockley - scientists signing up to a 'Berlin Declaration' imposing an effective 'test ban' on outdoor geoengineering experiments. Except there was no declaration, and scientists never agreed to it. The world's media got it completely wrong, yet the mud will stick - and may cause severe harm in the fight against climate change.
Even if you love Himalayan balsam, it has surely become too much of a good thing as it takes over Britain's wetlands and riverbanks. But now it's facing a major setback - the deliberate introduction of a parasitic rust fungus from its native range in the mountains of Asia.
Every now and then I am sent a book to review that is an absolute pleasure to read from cover to cover, writes Virginia Moffatt. This marvellous collection of interviews and essays by world-changing women activists is precisely one such book.
A newly-exposed report by Diablo Canyon's lead nuclear inspector shows that the twin reactors are unsafe, writes Karl Grossman. An earthquake on nearby geological faults could trigger a Fukushima-scale accident causing 10,000 early fatalities. The owner's response? Apply to extend the site's operation for another 20 years.
A High Court judgment on the lawfulness of the 2014 badger cull is awaited. A criminal investigation is under way on the dangerous and illegal behaviour of culling contractors. Obviously, writes Lesley Docksey, it's the perfect time for Natural England to authorise another round of culling.
After a 15-year battle, local campaigners infuriated by pollution, over-pumping of groundwater and land-grabbing have finally forced the closure of Coca-Cola's $25 million factory near Varanasi.
