The eco guide to population growth
Every hour 10,000 people are born. Fortunately a new crop of eco innovations will help tackle the pressures on our planet
The regularity with which I’m contacted by population worriers – people who think it’s pointless discussing green energy, climate change and ethical pensions when the elephant in the room is actually the new human in the room – is impressive. They say that the planet needs fewer people. End of.
The numbers are indeed eye catching. Today there are 7 billion humans alive (twice the number who were alive in 1965) – and each hour we add 10,000 more. By 2050, UN demographers predict, there will be at least 9 billion of us putting a strain on life-sustaining resources.

The shipping industry burns fossil fuels on a grand scale, and scarcely even tries to reduce its emissions
A seafaring adage goes: “If the winds are shifting, adjust your sails.” But even with the disturbing winds of climate change, the shipping industry, with its combustion of fossil fuels (accounting for 2.4% of global emissions), remains outside binding emissions-reduction agreements.
There have been some eco efforts, but the Carbon War Room points out that ship owners feel little need to green their fleets, as those hiring the vessels pay the fuel costs. When the price of bunker fuel (the sludgiest oil left over from refining) drops, as it has, eco resolve disappears.

How the ‘animal internet’ sheds light on the secrets of migration
Aristotle thought the mysterious silver eel emerged from the earth fully formed. The young Sigmund Freud could not understand how it reproduced, and modern biologists puzzled for years over whether it ever returned to the Sargasso Sea, where it was known to breed.
Last year a team of Canadian scientists found conclusive proof of that extraordinary journey. They strapped tracking devices to 38 eels and followed as they migrated more than 900 miles at a depth of nearly a mile to the Sargasso, in the Atlantic near Bermuda. This year French researchers used geolocators to watch them descending European rivers and passing through the Strait of Gibraltar, heading for the same spot.

Change in government’s energy policy blamed for job losses just as solar power eclipses coal in electricity generation
The solar power industry says it has seen the loss of more than half its 35,000 jobs due to recent changes in government energy policy, just at a time when solar power has eclipsed coal as a major generator of Britain’s electricity.
Experts believe ministers had cut subsidies too far and too fast, praising the “seismic”, record-breaking growth of solar in recent years.

Among elite mountain climbers, summiting Everest sans oxygen has become the latest challenge in an already grueling journey
Another climbing season has finished on Mount Everest, with the inevitable tales of tragedy and triumph.
Since 2000, an average of seven people a year have died on Everest. The past two years were especially grim: 19 people were killed by an earthquake-triggered avalanche in 2015, and 16 died in 2014.

British flower power: how home-grown blooms can compete with cheap imports
The UK spends more than £2bn on cut flowers per year, but around 90% are imported. Now a new breed of growers are determined to grab more of that market, by persuading the public that local and seasonal are the ways to go
Georgie Newbery sometimes has to dodge a hunting barn owl when she rises at 5am to harvest flowers on her seven-acre plot near Wincanton in Somerset. Picking sweet rocket, foxgloves and cornflowers as dawn light streaks over the fields may sound idyllic, but grabbing a cup of tea on a late-May afternoon after despatching her exclusively British-grown posies and bouquets, Newbery laughs at the thought. “If you imagine it’s all standing around in a flower garden with a Roberts radio and a robin singing, you couldn’t be more wrong,” she says, possibly a little tartly.

Vehicles are the source of a third of the air pollution in the Chinese capital, which restricts their use during episodes of heavy smog. Electric cars, buses, scooters and bicycles offer an alternative, cleaner form of transport
The humble daisy brings a smile to my face
South Uist The plant’s uses are many, but the sight of a sunlit field full of daisies is perhaps what we should value most
Daisies are one of our best known and most widely distributed wildflowers, and maybe this is why we sometimes pass them by with barely a second glance. This morning, though, they have stopped me in my tracks and brought a smile to my face.
They line the edge of the path, spangle the open grassland, and have so thoroughly covered one fenced pasture that almost all signs of grass have vanished beneath a blanket of white. In the warm sunshine each and every one turns a bright and open face skywards, a response that gave them their name “day’s eye”.

Light pollution 'affects 80% of global population'
Light pollution atlas shows areas of Earth that cannot see the stars – video
A team of scientists at the National Centers for Environmental Information in Boulder, Colorado have produced a digital atlas of the Earth that shows the levels of light pollution. The atlas makes use of low-light imaging now available from the NOAA/NASA Suomi National Polar-orbiting Partnership satellite, calibrated by thousands of ground observations. Light pollution is so severe in some parts of the world that a third of human beings cannot see the Milky Way

A poll of environmental professionals showed most think the UK benefits from EU air pollution rules
The UK’s air pollution crisis would get worse if the country votes to leave the European Union, according to a new poll of environment professionals.
The UK already has levels of air pollution above legal EU limits in many cities, resulting in 40,000 early deaths a year, while ministers are currently lobbying in Brussels against lower air pollution limits.
