Mrtvi šišmiši u Pitvama, srpanj 2019.

Jutra 24.07.2019. godine, dva mrtva šišmiša koja su ležala jedan pored drugoga na kućnom pragu, uznemirili su dvoje ukućana.

Iskusna veterinarka Susan Corning pregledala je sirota deformirana bića ali nije pronašla vanjske znakove ozljeda. Smrt dvaju šišmiša bez očitih ozljeda vrlo je neobična.

Ovo je dovelo Susan do sumnje da su šišmiši otrovani. Samo pet dana ranije, u petak 19.07., u ranim jutarnjim satima, lokalne vlasti izvele su drugu akciju zaprašivanja Opčine Jelse peretroidnim otrovom u ovoj sezoni. Slučajnost? Susan je, kao znastvenica, sumnjala da su dva događaja povezana. Uzrok smrti ne može se sa sigurnošću utvrditi bez ulaganja truda i novaca u obdukciju. Ali, obzirom da šišmiši jedu insekte, pa tako i komarce, to je mogao biti izvor unošenja otrova. Vlasti tvrde da je korišteni peretroidni otrov, Cipex 10E, “bezopasan za toplokrvna bića”. Ovo je neistinito. Utvrđeno je da aktivni sastojak Cipex-a, cipermetrin, može biti koban za mačke. Vjerojatno isto tako u visokim koncentracijama i za pse, te štetno i za ljude*. Djeluje na živčani sustav. Ako izravno ne ubije ciljne insekte, uzrokovat će nekontroliranu hiperaktivnost. Npr. 14. lipnja 2018. godine, jutro nakon akcije zaprašivanja kroz Pitve, ose su još uvijek imale posla s osinjakom kojeg su izgradile pored ceste, a koje je neizbježno zaprašeno koktelom otrova koje su te godine bile u uporabi. Broj im se, u odnosu na dan prije, smanjio a aktivnost preživjelih bio je nasumičan. Djelovalo je kao da sirota bića, usprkos svemu, pokušavaju raditi najbolje što znaju.

Tako će nakon akcija zaprašivanja otrovani insekti i dalje letjeti uokolo dok ih možda ne pojede ptica, šišmiš ili drugi insekti ostavljajući trag kolateralne štete. Detalji individualnih žrtava, kao što je smrt ovih šišmiša, možda se ne mogu sa sigurnošću znati. Nema sumnje da otrovi naneseni okolišu kroz akcije zaprašivanja doprinose razornom gubitku biološke raznolikosti na Hvaru. Kombinirani učinci pesticida koje lokalne vlasti koriste i onih koje koriste individualni poljoprivrednici i vrtlari uzrokuju ekološku katastrofu.

Šišmiši su jedni od tih, nekoć mnogobrojnih, stvorenja čija se brojka drastično smanjila.

Ljudi ne dolaze u Dalmaciju kako bi pronalazili mrtvu divljinu. Naprotiv, očekuju nezagađeni prirodni okoliš ispunjen divnim stvorenjima prirode. Jedini način da ispunimo njihovu želju jest da izbjegavamo u potpunosti korištenje kemijskih pesticida.

  • Campaigners in Henley say insufficient number of bathers to qualify for status is result of poor water quality

    Bathing water rules in England should be improved to help drive a clean-up of pollution at a spot on the River Thames in Henley, campaigners say.

    In a letter to the environment secretary, Emma Reynolds, businesses, river users, community groups and civic leaders said poor water quality had been damaging the town and had put public health at risk.

  • Council proposal to use glyphosate to tidy up pavements criticised over potential harm to humans and wildlife

    Cornwall is famed for its glorious gardens and verdant landscapes but a bitter row has broken out over a plan to tackle a less glamorous type of vegetation – roadside weeds.

    The unitary authority has announced plans to use the controversial herbicide glyphosate to tidy up pavements and kerbsides, after largely phasing out its use over the last decade amid concerns about potential harm to humans and the peninsula’s rich ecosystems.

  • Unwanted vessels left to decay release fibreglass shards into the water, harming marine life. Steve Green – with his trusty van Cecil – is determined to clean things up

    Steve Green, a boat engineer from Cornwall, was pulled over by the police just before Christmas. He was driving a decrepit-looking VW campervan and towing an even more dilapidated yacht up to Truro. He hadn’t broken any laws, but he admits that Cecil the campervan, which runs on donated chip oil from local pubs and has a crane and a winch on the front, “wasn’t quite what VW intended”.

    Green (and Cecil) are on a mission to rid the beautiful hidden creeks of Cornwall’s Helford and Fal rivers of 166 abandoned fibreglass yachts, which are leaking plastic and toxins into the predominantly marine waters. Marine biologists have likened the thousands of shards of fibreglass they have found embedded in the flesh of sea-creatures in areas with wrecks such as these to asbestos, a substance known to have a noxious effect on humans.

    Green uses a detachable crane system at the front of his van to move around bags of plastic after they have been weighed. Cecil is upholstered in recycled denim

  • Fiona Harvey tells Nosheen Iqbal why the climate crisis is a threat to national security

    “Last October, I and other journalists got quite excited because we thought that we were going to be attending a great event at the Natural History Museum,” the Guardian’s environment editor Fiona Harvey tells Nosheen Iqbal.

    “We had been told that there was a major report being launched at this event. And this report was going to come not just from where you’d expect – from the government’s environment department – but also from the joint intelligence committee, and they are the UK’s spy chiefs, MI5, MI6, the intelligence agencies. And they were taking an interest in the climate and biodiversity and the threats that they pose to the UK’s national security.”

  • About 500 farmers challenge Green Gen Cymru in high court over alleged disregard for landowners and biosecurity

    A group of 500 Welsh farmers have brought a landmark legal claim to the high court over the alleged conduct of a green energy developer planning to build electricity pylon routes across their land.

    The court will hear allegations that Green Gen Cymru “unlawfully sought entry to private land, intimidated landowners, and showed disregard for biosecurity and basic rights”, as well as examine laws that force landowners to sell property to utility companies, in a hearing on Tuesday and Wednesday.

  • St Mabyn, Cornwall: Many apiarists opened their hives this spring to find hardly any sign of life. In Richard’s case, he found nothing at all

    Richard Bray’s hives stand in a crooked line at the edge of the apple orchard, beside a low thicket of nettles. Richard was “brought up with” beekeeping here at Haywood farm, and at the peak of his apiary business had 250 hives; today he has seven. This spring, for the first time in 75 years, none of his bees survived the winter.

    Richard lifts the lid of the first hive, releasing a sour smell of old wax and honey. “There’s nothing,” he says, “that’s very worrying. You’d expect to [at least] see dead bees in there. But there isn’t a bee anywhere.” An inspector from the National Bee Unit advised that the loss was caused by the varroa mite, a notorious destroyer of bee colonies. “I’ve never had anything like this,” Richard tells me. “Varroa mite? I don’t know.”

  • One way to pay for wildlife conservation is to allow the rich to bag a few animals for high prices. But critics see this approach as an exercise in neocolonialism

    You can kill almost anything if you’re willing to pay. Big or small. Land, water or air. Ten a penny or one of the last of its kind. There’s nearly always a way, though it might not make you popular. The Niassa special reserve, a vast reservation larger than Switzerland, stretches for 190 miles along the northern rim of Mozambique, taking in 4.2m hectares of woodland and rivers. The reserve, one of the world’s largest protected areas, is home to elephants, leopards, hyenas, zebras and about 1,000 wild lions.

    That word, however: protected. It applies to some, but not all, of its animal inhabitants. Each year, a specific number are set aside for sacrifice, for the greater good. Not long ago,I joined an expedition in Niassa, with one of Africa’s top game-hunting companies.

  • As rising gold prices fuel environmental destruction, communities in the country’s biodiverse heartland are passing laws against mining

    Mahogany trees tower above Herminio Mamani as he tends his cacao farm in Bolivia’s biodiverse north-west. A former president of El Ceibo, the country’s largest organic cacao co-operative, he says the agroforestry model used by its 1,300 members is vital not only to maintain the quality of the cacao they produce, but also for keeping gold mining at bay.

    “We cacao producers would never kill an animal here,” he says, parrots squawking nearby. “The parcels [of land] can never be monocultures – all the crops grow together.”

  • Analysis of video footage reveals how wave changed as it travelled over mud-rich rice paddies, exerting more force

    It is just over 15 years since the devastating Tohoku earthquake and tsunami struck Japan, killing almost 20,000 people and triggering the Fukushima Daiichi nuclear disaster. Fresh analysis of video footage of the wave has revealed that the mud-rich coastline made the tsunami far more destructive than it might otherwise have been.

    Patrick Sharrocks, from the University of Leeds, and colleagues studied helicopter video footage, along with before and after images from Google Earth, to estimate the speed, shape and power of the tsunami flow front. They found that as the wave travelled over mud-rich rice paddies it changed from a fast-moving, clear-water flow into a thick, gloopy, mud-laden one.

  • The country is seeing an increase in human-wildlife conflict as the number of megafauna, including rhinos and tigers, grows. But there are efforts to tackle the problem around Chitwan national park through education and training

    The tourists lining the steep embankment buzzed with excitement, phones out, snapping away in the twilight as a wild Indian rhinoceros grazed below the Nepali village of Sauraha. Climbing to the main street, the rhino ambled down the middle of the road.

    Local people warned tourists to give it plenty of space. All manner of wheeled vehicles slowed, then passed. The rhino turned its horn at a cyclist passing too close, triggering gasps from the assembled crowd.
