My admiration for Peter Tatchell has been boosted by his admission that he was wrong about an issue (I’ve changed my mind on the gay cake row, 1 February). We need more people in public life who are prepared to admit they were wrong.

Deal marries interests of First Nations, environmentalists and logging industry, who will see 15% of Great Bear forest available under ‘most stringent’ standardsBritish Columbia is set to announce a historic agreement to protect a vast swath of rainforest along its coastline, having reached a deal that marries the interests of First Nations, the logging industry and environmentalists after a decade of often-tense negotiations.

A consortium of Dutch government, NGOs and businesses has proposed solutions to Guanabara Bay’s pollution. But cash-strapped Brazil can’t payWith the Olympic Games just months away, Rio de Janeiro has a problem: rubbish. Hundreds of tonnes of unprocessed waste flow into the Guanabara Bay every year. The problem isn’t new but the prospect of Olympic swimmers and sailors taking to Rio’s contaminated waters have put the issue in the spotlight.Previous promises from Rio officials to “regenerate Rio’s magnificent waterways” through investment in sanitation have not delivered results. Could the Dutch environment ministry have better luck? In an ambitious and diplomatically unorthodox move it has pulled together some of the country’s leading waste experts, including businesses and NGOs, to propose a variety of innovative solutions under the name Clean Urban Delta Initiative [pdf].

The growth in renewable energy is fuelling new jobs in Asia and Africa. Meet three beneficiaries of the new green economy from Zambia, Pakistan and KenyaWhile the price of oil is plummeting, taking with it a significant number of jobs, the renewable energy job market is booming. It is estimated that it will grow to 24m jobs worldwide by 2030 – up from 9.2m reported in 2014 – according to analysis by the International Renewable Energy Industry (Irena), which predicts that doubling the proportion of renewables in the global energy mix would increase GDP by up to $1.3tn across the world.The rise and rise of the solar industry has been the largest driver of growth. In 2014, it accounted for more than 2.5m jobs, largely in operations, maintenance and manufacturing – now increasingly dominated by a jobs boom in Asia. Continue reading...

The secret life of a pig farmer: I don’t earn enough, given the hours I work and the injuries I get. But at least David Cameron hasn’t bothered my animals yetHaving worked in administration for over 10 years, the decision to pursue a career in farming may perhaps not have seemed the obvious choice for a 28-year-old woman, but four years ago that is exactly what I did. Following a serious health scare, the opportunity to get involved with the family business was something that I didn’t want to pass up. I left a job that I loved and my life in the city and moved 100 miles away to run a 300-acre mixed arable and livestock farm in a rural area.Related: Cheap imports force UK pig farmers out of business Continue reading...

Annandale, Dumfries and Galloway We inhabit the same earth, the coal tits and I, but live in different worlds. I can fly at liberty around mine but cannot hope to enter theirs. Looking at their lives is like peering down at a country where I cannot land.The sky is overcast and the air smells softly of smoke in the still, snow-muffled high reaches of Annandale above Moffat. From within a dark stand of conifers comes a chirping as soft as grasshoppers. The source is a band of coal tits, their subtle winter-coloured plumage a match for the surrounding environment.These birds are biologically distinct in part because of their adaptations to life in coniferous woodland, with a more slender beak than blue or great tits. Tiny tufts of snow sit precariously on the sprigs of the branches but somehow stay in place as the birds rummage within the needles for insect food, so delicate is their fidgety but precise work.

The company has won plaudits for its admission of forced labour in the Thai seafood industry but much of the supply chain remains hiddenIt’s hard to think of an issue that you would less like your company to be associated with than modern slavery. Yet last November Nestlé, the world’s largest foodmaker and one of the most recognisable household brands, went public with the news it had found forced labour in its supply chains in Thailand and that its customers were buying products tainted with the blood and sweat of poor, unpaid and abused migrant workers.By independently disclosing that Nestlé customers had unwittingly bought products contaminated by the very worst labour abuses, the company said it was moving into a new era of self-policing of its own supply chains. A year-long investigation by the company confirmed media reports that the seafood industry in Thailand is riddled with forced labour and human trafficking and that slave labour was involved in the production of its Fancy Feast catfood brand.

Originally published in the Manchester Guardian on 4 February 1916The sleepers awaken; indeed in many cases winter slumbers have been light and fitful. Up and down the lane, between and round the black-budded ashes and above the grassy borders, where pale green nettles form thick and treacherous beds for those who would pick the first flowers, the bats fly at dusk. Early this week it was not one bold straggler who had ventured out to test the weather, but whole colonies were on the wing; in less than a mile I counted ten different bats, and at least of two species. Evidently it was not a disappointing effort on their part, for the air was full of dancing winter gnats, though no doubt less full when the bats ended their crepuscular flight.A correspondent, writing from Old Colwyn, speaks of another early riser, a small tortoise-shell butterfly, which she saw sunning its beautiful wings. In autumn this fly sought out some sheltered and cosy retreat, and, folding those many-coloured wings so that the marbled under-surface alone was visible, slept the sleep of the just - dreamless or otherwise we cannot tell. Unlike too energetic wasps, however, its awakening will probably not be useless; it can fulfil its life-history. The same warm touch which stirred its stiffened limbs had pushed on those young nettles beneath the hedge: they are ready to receive the eggs which the fly has waited so long and patiently to give them. She may have emerged late in the autumn, and at once, after one rapturous nuptial flight, have sunk into winter oblivion, and, when the nettle bed is found and provided with its future colony of stiff-spined caterpillars, she may pass at once into the deeper sleep of death; but if the eggs are safely deposited, however short her life as a perfect insect, she will have played her part in the economy of nature.

Every hour or so the “Old Faithful” geyser in Yellowstone National Park, Wyoming, shoots a column of boiling water up to 50m into the air. This incredible natural spectacle, along with multiple other geothermal features and the one to two thousand earthquakes that occur every year, are just some of the signs that this region is sitting atop a whopping great volcano. The last super-eruption was nearly 640,000 years ago, but gentle swelling of the ground indicates that the underlying magma chamber is refilling, and Yellowstone will erupt again one day.Related: Yellowstone national park: scientists discover huge magma chamber Continue reading...

National Audit Office to investigate taxpayer value for money in George Osborne’s scrapping of CCS and question plans to secure UK energy supplyThe National Audit Office is to investigate George Osborne’s decision to scrap a £1bn prototype carbon capture scheme which cost the taxpayer at least £60m, a letter seen by the Guardian shows.

Aberdeen and the UK oil industry have been promised £500m in state help while support for renewables and carbon capture has been slashed. The future of the UK’s energy capital should be green, not blackThat the government should step in with £250m to help ailing Aberdeen, the centre of Britain’s oil and gas industry, seems right given the billions in tax revenues ministers have extracted from the North Sea over several decades. And though it might seem counterintuitive to come to the rescue of a city built on fossil fuels – given the threat of global warming – it also makes sense for Britain to keep producing its own oil and gas until it can find ways of doing without them.

Solar sector needs better power storage, grid infrastructure and government support to meet bullish growth predictionsSixty years ago, the price of solar panels was astronomical. At a cost of $1,910 (£1,350) per watt in today’s money, the only practical use for them was in space on the US Vanguard 1 satellite, which launched in 1958.

In the UK we need to double our planting rate over the next 50 years if we want our woodlands to surviveIt is hard to overestimate the value of trees. They are carbon sinks that keep us alive. They suck up pollution and soak up water. For more ways in which trees rock, the Trees and Design Action Group has a list in its report, No Trees No Future – an apocalyptic title that highlights their importance.Yet, although we may profess to love trees, the UK is one of the least-wooded countries in Europe. Woodland covers just 12% of the land. What’s good about trees is that you can always plant more, but we are not too hot at that, either. The planting of broadland species (as opposed to mineral-leaching fast-growing conifers) has halved over the last six years. Continue reading...

Mere acknowledgement that the environment is in peril without a plan to mitigate it is a huge oversightLet’s call it the non-denial denial. Some Republican presidential candidates are beginning to peer out from behind the wall of climate denial that has defined the party as long as Barack Obama has been in the White House. Finally, it seems, the most open expressions of climate denial – such as dismissing long-established scientific fact – may be seen as a bit retrograde, and possibly embarrassing, even by some who are looking for votes from an increasingly rightwing Republican party.In response to a rare question about climate change in Thursday night’s Republican debate, Marco Rubio offered up an answer that was rarer still in the 2016 campaign. He did not reduce climate change to a punchline or bash the science underlying climate change, as Ted Cruz and Donald Trump have been doing throughout the primary. Continue reading...

Cadair Idris, Dolgellau The only sound was the roar of falling water, as the Nant Cadair sluiced over the rocks. Deep moss and clumps of fern cling to the stone walls in the oak wood, wrapping the walker in a soft acoustic cocoonThe weather looked untrustworthy at best, and it was clear from the outset that our ascent of Cadair Idris was unlikely to be complete. From the avenue of trees that forms the approach to the Minffordd path, the summit itself is hidden by the steep sides of the glaciated valley, but cloud loomed ominously over the crags of Moelfryn.Deep in the valley, the air was still and bitterly cold. The only sound was the almost random roar of falling water, as the Nant Cadair – swollen by meltwater – sluiced over the rocks into the deep, clear pools that look so tempting in warmer weather. Deep moss and clumps of fern cling to the stone walls and boulders in the oak wood, moderating the sound and wrapping the walker in a soft acoustic cocoon. Continue reading...

As rising sea levels threaten their state of Florida, fellow Republican candidate Marco Rubio also warns that action on climate would ‘destroy’ the economyFlorida’s leading candidates for the Republican presidential nomination, Marco Rubio and Jeb Bush, have both criticized federal action to combat climate change, with Rubio warning it would “destroy” the US economy and Bush predicting “someone in a garage somewhere” will solve the problem instead.

Your recent article (Build on flood plains despite the risks, say UK government advisors, 28 January) misrepresents the evidence I gave to the House of Commons environmental audit committee on 27 January. The evidence I gave, as presented in my committee’s report to parliament last summer, is that building in areas of flood risk is storing up costs and risks for the future, especially in the context of climate change. Despite the safeguards within the planning system, 4,600 new homes are being built every year in areas that are at higher risk of flooding than many of the UK towns and cities hit by the recent storms.My committee accepts that there will be circumstances in which local councils approve flood plain development. Where this occurs, the new buildings and urban landscapes should be designed to be flood resilient. Prospective purchasers should be made fully aware of the risks including the implications for flood insurance. Furthermore, the government should no longer ignore the long-term costs for society that will result from an ever-increasing number of properties on the flood plain.

Kitted out with video cameras and satellite trackers, 10 vultures have been set loose over the capital of Peru to draw attention to the megacity’s overwhelming trash problem – though not necessarily to clean it upSome cities have pigeons. Lima has black vultures, or gallinazos. They circle in groups overhead and perch on the city’s most emblematic buildings – the decrepit, colonial-era churches and crumbling 18-century piles in the city’s downtown. In many ways, with their wrinkly heads and beady eyes, they remind Lima residents of the side of their city they would rather ignore: the neglect, poverty and filth.But these carrion-eaters’ natural affinity for dead and decaying things is being turned into a virtue. Environmental authorities are giving these much-maligned birds a PR makeover, kitting them out with GoPro video cameras and GPS trackers, and giving them a new mission in the fight against fly-tipping and illegal dumping.

‘Food-conditioning’ and other adaptive behaviors have become common among bear populations – and could lead them into dangerous contact with humansWilliam Hefner was on his honeymoon with his new wife Sara, driving back to their rented condo in the mountains above Gatlinberg, Tennessee, when he first saw the bear. At first, he said, he thought it was a huge dog nosing around. They followed it in the car; Hefner started videoing.
