Study on rats said to show that the chemical, found in Monsanto’s Roundup weedkiller, poses ‘a significant public health concern’

A chemical found in the world’s most widely used weedkiller can have disrupting effects on sexual development, genes and beneficial gut bacteria at doses considered safe, according to a wide-ranging pilot study in rats.

Glyphosate is the core ingredient in Monsanto’s Roundup herbicide and levels found in the human bloodstream have spiked by more than a 1,000% in the last two decades.

Government-commissioned report says proposed site at Sambor reach is the ‘worst possible place’ for hydropower due to impact on wildlife

A Chinese-backed plan to build Cambodia’s biggest dam could “literally kill” the Mekong river, according to a confidential assessment seen by the Guardian which says that the proposed site at Sambor is the “worst possible place” for hydropower.

The report, which was commissioned by the government in Phnom Penh, has been kept secret since it was submitted last year, prompting concerns that ministers are inclined to push ahead regardless of the dire impact it predicts on river dolphins and one of the world’s largest migrations of freshwater fish.

News of milestone comes as MPs say policy changes have caused collapse in investment in renewables

Britain’s windfarms provided more electricity than its eight nuclear power stations in the first three months of 2018, marking the first time wind has overtaken nuclear across a quarter.

The renewable energy industry hailed the milestone as a sign the UK was well on its way to an electricity system powered by cheap, domestic green energy.

Electric Vehicles will help lessen Australia's dependence of fossil fuel imports, and provide cheaper and cleaner transport. But is the oil industry ready for this? Apparently not.

Kit Hill and Metherell, Tamar Valley: This pear tree remains spectacular, with creamy blossom on wide-spreading branches

At dawn, birdsong floats up from shrubby undergrowth towards the cold summit of Kit Hill. Mist lies in the lowest valleys and, like the scattered enclaves of yellow oilseed rape and plastic-covered maize plantings, appears luminous among the pale greens and blues of the expansive patchwork of fields and woods.

The first cuckoo call of the season impels a brief runabout in honour of family tradition to ensure another year of liveliness – although my predecessors would have had no need to come uphill and away from the valley to hear this bird. The sound of melodeon, trombone, drum and bells echoes around the monumental mine-stack as the Cornish Wreckers dance morris in celebration of May and of “winter gone away”.

Japanese knotweed is said to cost UK economy £170m a year, but so far only solution is controversial glyphosate-based herbicide

Japanese knotweed is a thug of a plant capable of growing a foot a week at this time of year; it spreads rapidly from underground rhizomes; erodes riverbanks, leading to flooding; smothers other plants; blocks drains and wreaks such havoc on homes and gardens that it blights property prices. It is estimated that controlling Japanese knotweed costs the UK economy about £170m each year. An entire industry has been built on trying to control the plant, using at least 15 different active control methods. There is, however, no impartial study of how effective any of these treatments are.

Scientists at Swansea University recently concluded the world’s largest field trial over five years on tackling Japanese knotweed. Their depressing assessment is that eradicating the plant using weedkillers is useless, and so too are physical methods such as covering up and cutting down knotweed.
