In Sussex scientists have found that insecticide use has stabilised over the past two decades with an associated stabilisation of some insect groups, write Dr Julie Ewald and Prof John Holland of the Game & Wildlife Conservation Trust. Plus Judith Wright says we should let verges grow

It is with great interest that we read about the long-term decline in the biomass of flying insects on German protected areas (Scientists tell of alarm at huge fall in flying insects, 19 October).

The Game & Wildlife Conservation Trust (GWCT) carries out two long-term surveys of insects on farmland in England – the Sussex Study (1970 to present) and at our demonstration farm in Loddington (1992 to present).

Roads minister Jesse Norman says government could push councils to do more to fight pollution and inactive living

The UK government could potentially consider providing subsidies for electric bicycles and electric cars as part of a concerted policy effort to get more people cycling, the roads minister, Jesse Norman, has said.

With the UK facing health crises from pollution and inactive living, other plans could include using electric cargo bikes to deliver packages from internet retailers rather than vans, Norman told the Guardian.

Big Moor, Derbyshire The stag ignores the passing lorries but isn’t ready for a photographic closeup

Running south from the old Barbrook reservoir, I found myself struggling against the strong south-westerly that had kept temperatures unusually high for several days and delayed wintering thrushes returning to the moors. The arrival of fieldfares and redwings is always sparkling compensation for the gloomy approach of winter but I would have to wait a little longer. At least the sun was out, turning the sprung shoulders of a kestrel to a vibrant caramel as it quartered the brook below me.

Almost as I reached the Baslow road the sunlight picked out a red deer stag standing tall some distance away, antlers raised, breath steaming from its flared nostrils. At the same time I caught sight of another beast advancing towards the stag with an enormous-lensed camera held to his eye.

A hydro-electric power station on the state’s largest dam – Burdekin Falls Dam – to secure energy and support jobs for North Queensland moved a step closer today.

Anger deepens over politicisation of Energy Security Board and design of National Energy Guarantee that could reinforce dominance of incumbent utilities, stop large scale renewables, maintain status quo and fail emissions targets. But some say it does have potential.

Genex Power's Kidston solar and pumped hydro plant could provide 2000MWh of storage, and 8 hours of continuous generation, rather than six.

If you ask mainstream media, renewables are the key driver of Australia's rising power prices; a scourge that's at its worst in South Australia. Yeah, nah.

BNEF say new Coalition plan could see 42% renewables by 2030, the same as Finkel. But rooftop solar will account for most new installations, and large scale wind and solar could be sidelined by coal extensions. Still, BNEF describe it as innovative and elegant.

IEA says coal will be used to provide access to electricity to just 16% of those without electricity now, while renewables will account for at least 60%.

Landmark study finds toxic air, water, soils and workplaces kill at least 9m people and cost trillions of dollars every year

Pollution kills at least nine million people and costs trillions of dollars every year, according to the most comprehensive global analysis to date, which warns the crisis “threatens the continuing survival of human societies”.

Toxic air, water, soils and workplaces are responsible for the diseases that kill one in every six people around the world, the landmark report found, and the true total could be millions higher because the impact of many pollutants are poorly understood. The deaths attributed to pollution are triple those from Aids, malaria and tuberculosis combined.

Researchers say UK’s enthusiasm for bird feeders compared with mainland Europe responsible for increase in beak length

The reason some birds in Britain have evolved bigger beaks over the past 40 years may be down to the country’s enthusiasm for feeding them in their gardens, researchers have said.

The report published on Thursday in the US journal Science compared beak length among great tits in Britain and the Netherlands, where bird feeders are less common.
