Securing a former prime minister to speak at your organisation is no doubt a coup for many groups.

Burdekin, Fitzroy, Tully and Daintree rivers in Queensland pose greatest risk, researchers find

Four rivers are most responsible for polluting the Great Barrier Reef, according to research that scientists hope will help governments better target efforts to reduce damage to the reef from land use.

The Burdekin, Fitzroy, Tully and Daintree rivers in Queensland posed the greatest risk to the reef, the study led by The Nature Conservancy and the University of Queensland found.

Research involving 62 species found mammals spent relatively less time being active during the day when humans were nearby

Human disturbance is turning mammals into night owls, with species becoming more nocturnal when people are around, research has revealed.

The study, encompassing 62 species from around the globe, found that when humans were nearby, mammals spent relatively less time being active during the day and were more active at night - even among those already classed as nocturnal.

Readers respond to Chris Packham’s recent observations on environmental destruction, and to the suggestion that one positive step would be for us to give up our pets

If we’ve normalised the ecological damage we are doing to our country, as Chris Packham suggests, it’s only because as individuals we feel helpless (Packham: ‘We are presiding over ecological apocalypse’, 11 June). As it is, the signs are extraordinary, and not just the absence of iconic species like butterflies, bees, frogs and hedgehogs. I have noticed a decline in the number (and size) of ticks, for example, and houseflies and greenflies – even dung flies – are actually rare this summer.

If we do not mourn their decline we are foolish – no flies means no maggots, which means no cleaning up of the dead badgers Packham mentions; no greenflies and ticks means less food for some species up the food chain, which is presumably why there are no birds on our feeders these days. It really does feel like an apocalypse, and yet the government still drags its feet over the poisons which have almost certainly caused it.

Enbridge wants to build a new tar sands pipeline

Tar sands are the dirtiest fossil fuels. These are low-quality heavy tar-like oils that are mined from sand or rock. Much of the mining occurs in Alberta Canada, but it is also mined elsewhere, in lesser quantities.

Tar sands are the worst. Not only are they really hard to get out of the ground, requiring enormous amounts of energy; not only are they difficult to transport and to refine; not only are they more polluting than regular oils; they even have a by-product called ”petcoke” that’s used in power plants, but is dirtier than regular coal.

EU lawmakers struck a provisional deal on a 2030 target of 32% renewables early Thursday but failed to reach agreement on an energy efficiency bill.

Circular economy could recycle more plastic and meet industry demand for raw materials, finds Green Alliance research

Plastic recycled in the UK could supply nearly three-quarters of domestic demand for products and packaging if the government took action to build the industry, a new report said on Thursday.

The UK consumes 3.3m tonnes of plastic annually, the report says, but exports two-thirds to be recycled. It is only able to recycle 9% domestically.

Samsung Electronics officially announced today its plan to commit to 100% renewable energy in the United States, Europe and China by 2020.

The economic boom, the pressure of immigration, and high emissions in transport mean that the energy transition pioneer is headed for a greenhouse gas emission cut of only 32%.

Sandy, Bedfordshire: The smaller birds lunged and jabbed with mute jibes that might have said: ‘Egg thief! Chick killer! Get out of our territory!’

All through the spring, mewling cries of raptors have scolded out of thin air. On clear-sky days such as this the buzzard is complainer-in-chief, condemned by nature to speak only in a minor key. Even in the exaltation of soaring, the uplift of raised wings is accompanied by a downbeat of dissatisfaction. Nevertheless, the buzzard demonstrates moments of great expressiveness, when its peevish tones are transformed into genuine distress.

Such a mayday came just as I was sauntering down the long slope from Sheerhatch Wood. The call had me swivelling round to scan over the trees, only to be turned again by a pained cry that seemed to be coming from the opposite direction. The buzzard was flying overhead, assaulted front, back and sides by a pair of crows. The smaller birds were intent on ruffling a few feathers, lunging and jabbing with mute jibes that might have said: “Egg thief! Chick killer! Get out of our territory!” The hapless buzzard, their sworn-at enemy, flapped in loud desperation, unable to rid itself of its turbulent assailants.
