Dead bats in Pitve, July 2019

Two dead bats lying close together on their doorstep were a sad surprise which greeted a couple in Pitve on the morning of July 24th 2019.

Experienced veterinarian Susan Corning looked over the poor distorted creatures and could see no sign of external wounds. The death of a pair of bats with no obvious evidence of injury is unusual.

This led Susan to the suspicion that the bats might have died from poison. Just five days previously, in the early hours of Friday July 19th, the local authorites had performed the second 'fogging' action of the season, spraying the streets  throughout the Jelsa Council region with pyrethroid poison. Was this a coincidence? As a scientist, Susan was suspicious that the two events might be connected. Without going to the trouble and expense of an autopsy, the cause of death cannot be certain. But as bats eat insects, including mosquitoes, that might have been a source of ingestion. The authorities claim that the pyrethroid used, Cipex 10E, is 'harmless to warm-blooded creatures'. This is untrue. It is well established that the active ingredient of Cipex, Cypermethrin, can be fatal to cats. It is probably also toxic to dogs in high concentration, as well as being harmful to humans*. Its action is on the nervous system. If it does not kill the target insects outright, it causes frenetic hyperactivity. On 14th June 2018, for instance, the morning following the 'fogging' action through Pitve, wasps were still busy around a nest they had built right by the road, which had inevitably been sprayed with the cocktail of poisons used that year. Their numbers were reduced from the previous day, and the activity of the survivors was haphazard. It looked as if the poor souls were trying to do their best, against the odds.

So, after the fogging actions,  poisoned insects will still be flying about to be eaten by birds, bats and other insects, causing a trail of collateral damage. Details of individual cases like these bat deaths may be open to question. There is no doubt that the poisons inflicted on the environment by the fogging actions are contributing to a devastating loss of biodiversity on Hvar. The combined effects of the pesticides used by the local auithorities and those used by individual farmers and gardeners are causing ecological disaster. Bats are among those once-plentiful creatures whose numbers have declined drastically.

Finding dead wildlife is not what people come to Dalmatia for. On the contrary, they expect a clean, unpolluted natural environment, filled with nature's exquisite creatures. The only way to fulfil their wish is for the island to 'go organic'!

  • Mines in supply chains of western carmakers linked to widespread deforestation of primary rainforest in nickel-rich lands inhabited by Tolaki people in Indonesia

    Volkswagen, Ford and Tesla are among the electric carmakers whose batteries may contain nickel mined in indigenous woodlands plagued by deforestation, an analysis has found, highlighting the struggle to make vehicles that are free from environmental destruction.

    Corporate disclosures and trade flows from the last two years show mines in the battery supply chains of automotive giants are linked to the loss of trees in Sulawesi, a wildlife hotspot in Indonesia that houses the world’s largest nickel deposits. The metal is widely used in cathodes in car batteries because it boosts energy density and increases range.

  • Some reservoirs in south at critical levels as water companies call for extended restrictions that would affect golf clubs, private schools and car washes

    A severe drought has been declared in six areas of England, with some reservoirs at critically low levels, threatening public supplies.

    Parts of Devon, Cornwall, Dorset, Somerset, East Sussex and West Sussex have moved into severe drought, and urgent measures are being taken to secure public supplies of water after the UK experienced its hottest summer on record.

  • How architects worked with harsh environment to create sustainable building in location where fossils were found

    Viewed from afar, the silver-hued Hami Pterosaur Museum almost looks like a space base on Mars. Viewed from above, it resembles a collection of dinosaur eggs in the sand. Nestled in the Gobi desert, in north-west China, the new tourist attraction showcases hundreds of impressive fossils of pterosaurs, ancient flying reptiles related to dinosaurs. But far from reflecting its prehistoric exhibits, the building itself is a modern-day architectural specimen.

    Designed with underground exhibition halls, giant light funnels and sprawling solar farms, the museum is able to operate sustainably while withstanding an extremely harsh environment.

  • Golden Valley, Herefordshire: Even vicars can get stuck too much behind a desk, and the 800th anniversary of St Francis of Assisi’s death is a good excuse to strike out, and speak to local people

    I was sitting at my desk again, with the dull hum and the blue glow of the screen. It seems that every occupation traps people at their desk, and being a vicar is no different. But I wanted to resist, and it happened to be the 800th anniversary of Saint Francis of Assisi’s death. With Jesus of Galilee as inspiration, Saint Francis was known for his vow of simplicity, his love of the Earth and his critique of the wealth accumulated by the religious elite at the expense of the poor. He was also horrified by the Fifth Crusade, so he travelled to Egypt, hoping to make peace.

    Francis also walked the walk, as it were, sleeping in caves in the Umbrian hills, taking nothing with him. No sitting at the desk for Francis. So I decided to do the same, spending three days walking the bridleways, holloways, footpaths and country lanes of the Golden Valley, speaking to people along the way. My sanctuary for the night was one of my parish churches – Madley, Tyberton, then Peterchurch, with its very welcome underfloor heating.

  • As climate breakdown pushes families to starvation, many feel forced to ‘sacrifice’ daughters to save siblings. Photographer Elise Blanchard travelled the country speaking to girls as young as eight, 10 and 14 who have been engaged or married to repay debts or pay for food

    ‘I’m not happy about this,” says 11-year-old Khatira, who was sold into marriage to repay debts, sitting in her home in Qala-e-Naw, capital of Badghis province in north-west Afghanistan. “She was healthy before her engagement, now she is worried and cries a lot,” says her 40-year-old mother, Noor Bibi.

    When her 20-year-old husband-to-be comes to her home, Khatira runs away. Since her engagement, she has stopped going outside because she “is ashamed of having a husband in front of the other girls”, says her mother.

  • Peru’s anchoveta have made up about a 10th of the entire global commercial fishing catch since 1970, more than any other fish. A combination of warming seas and decades-long overfishing spells disaster

    On 10 June 2026, the government of Peru made a decision that it knew would hurt one of the world’s major fishing industries. It stoppedall anchoveta fishing boats from going out to sea, suspending the fishing season. At first the order was temporary, but in mid-August, the suspension turned into a total closure. This was no easy call. For one thing, it was a brutal blow to the Peruvian economy.

    Peruvian anchovies – the scientific name is Engraulis ringens – are not the salty, punch-packing little fillets in a puttanesca sauce or caesar salad dressing. That is a different species – Engraulisencrasicolus – which is smaller, tastier and found mostly in the eastern Atlantic and the Mediterranean. Only a small part of Peru’s anchoveta catch is eaten in fish form. The rest – more than 90% – is immediately processed as fishmeal and fish oil, packed in sacks and barrels, and shipped to fish, shellfish and seaweed farms, factory farms and nutritional supplement producers around the world.

  • Millions affected by smoke from wildfires as schools close, respiratory illnesses soar and diplomatic tensions rise

    Singapore is threatening to prosecute companies responsible for some of the worst fires in years in neighbouring Indonesia, as the region grows increasingly frustrated with a persistent, acrid haze that could result in diplomatic relations fraying.

    Lawrence Wong, the Singaporean prime minister, said his government was distributing masks to vulnerable citizens and working with countries in the region to deal with the smoke. “At the same time, we are looking into which companies may be responsible for the fires,” he said in a Facebook post on Thursday, adding that he was exploring the idea of “joint action with other countries”.

  • ​The world pledged to halt biodiversity loss by 2030, but as Cop17 delegates meet in Armenia next week the outlook is bleak and optimism has faded

    The world has lost its way on nature once again. Next week, biodiversity Cop17 begins in Yerevan, Armenia, and expectations are low. Very low.

    Almost four years ago, governments reached an historic agreement at the biodiversity Cop15 to halt the destruction of Earth’s ecosystems – to rapturous applause in Montreal, Canada. I still remember the excitement in the hall in the early hours of that freezing December morning.

  • US research says nitrogen dioxide in restaurants that cook with gas can exceed WHO limits, which also affects diners

    Each time we enjoy a meal out or order a takeaway, someone cooks for us in a commercial kitchen. In the UK, 3.6 million people work in catering and hospitality. In the US it is estimated at close to 16 million. A first-of-its-kind study in the US has found catering staff can experience high air pollution at work – and that this can affect diners too.

    Dr Drew Michanowicz, senior author of the study at non-profit research institute PSE Healthy Energy, said: “I was motivated by what we have learned over the years about what just 30 minutes of gas cooking can do to air quality in homes with the realisation that millions of people cook for a living for hours on end.”
