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.

  • Parts of England expected to hit 35C in ‘unprecedented’ May heatwave

    Monday predicted to be hottest May day on record by large margin, as UK braces for ‘super El Niño’ summer

    Temperatures are expected to hit 35C in parts of England on Monday, in an “unprecedented” May heatwave.

    The Met Office is already predicting that records will be broken. A spokesperson said: “Today will be the hottest day in May in the UK in our temperature records, with highs of 35C expected. The current May record is 32.8C. Records are usually only broken by tenths of a degree, making this heatwave unprecedented for the time of year.”

  • Weather tracker: flash floods in New York and a heat dome in Europe

    Rain overwhelms sewer system in parts of US city, while temperatures in France break May record

    New York City saw flash flooding on Wednesday, as large parts of Brooklyn and Queens received about 2in (50mm) of rainfall in as little as 20 minutes. Officials said the deluge caused water to flow into the sewer system at a rate of up to 6in an hour, quickly overwhelming an aged network that was designed to accommodate just 1.75in an hour.

    Residents and commuters found themselves wading knee-deep through flood water that flowed with dangerous speed in places. One video showed a woman alighting from a bus losing her footing and being dragged along by the torrent of water. Several major roads were blocked, including the Long Island Expressway, and subway services were disrupted as water spilled into stations. Large amounts of mud and other debris was left behind; videos showed bags of rubbish being swept down streets along with loose litter.

  • Half of UK adults say they spend less than three hours a week outside in nature

    Most people have joyful memories of playing outside as children – and now wildlife charities are urging people to ‘rewild their inner child’

    Climbing trees, squelching in mud, paddling in ponds or making dens in the woods – people’s memories of playing outside as children are often vivid and, a new poll has found, overwhelmingly positive, even those who remember falling in cowpats.

    Almost 90% of UK adults had rosy memories of the excitement and the feeling of freedom that outdoor play had brought them, the survey found. However, almost half of adults now spend less than three hours a week in natural settings such as gardens, parks, fields or woods, according to the survey. For one in 10 it is less than one hour.

  • River Wye granted rights in UK first that could help in fight against pollution

    Charter to be adopted along river’s entire catchment from Cambrian mountains to Chepstow and Bristol Channel

    The entire catchment of the River Wye has been formally recognised as a living ecosystem with intrinsic rights in a charter, a UK first that campaigners hope will help save the highly polluted river.

    The charter was celebrated at a community event at the Hay-on-Wye literary festival on Sunday. It includes the right to flow, to biodiversity, to be free from pollution, to be supported by a healthy catchment, to regenerate, and the right to be represented, described as a “significant step” towards protecting and restoring one of the UK’s most beloved rivers.

  • Scotland’s ‘green datacentres’ policy ignores emissions impact of AI, analysis shows

    Definition of green facilities made in 2022, before release of ChatGPT, says Action to Protect Rural Scotland

    A Scottish government policy designed to encourage datacentres to build in Scotland could lead to a massive volume of carbon emissions being ignored, according to an analysis by a Scottish charity.

    “Green datacentres” are at the heart of Scotland’s ambitions to develop economically. Enshrined in national policy, they are part of a larger, UK-wide effort to attract big AI investment to Scotland.

  • Country diary: One turn inland, and the valley opens up before me | John Gilbey

    Talybont, Ceredigion: On a crisp, post-rain morning, I take a walk among bright hawthorn blossom and the glittering pools of Cors Fochno

    On the edge of Talybont, the small cemetery, kempt and cared for, overlooks the coast and the wild brown swathe of Cors Fochno (Borth Bog). A burial ground is perhaps an odd place to begin a walk, but, as a friend remarked, it’s infinitely better than ending one there.

    The early rain has cleared so the air is crisp and the colours deep. In the foreground, grassland fields slope away towards the wild expanse of the bog, bounded by wooded hedgerows bright with hawthorn blossom. The first cut of silage has been secured, baled and removed, and a few cattle are grazing the aftermath with interest while red kites traverse overhead. The surface of the bog, marked here and there by glittering open pools, shimmers slightly in the heat of the day. Across the Afon Dyfi, the steep-faced sand dunes of Aberdyfi are visible before the eye is drawn further off to the line of hills that defines the Llŷn peninsula.

  • UK records hottest day of year as forecasters warn of more extreme heat

    Temperature reaches 30.5C in Kent as amber health alerts issued before bank holiday temperatures rise

    The UK has recorded its hottest day of the year so far, with temperatures reaching 30.5C in Kent as forecasters warned more extreme heat could follow over the bank holiday weekend.

    The temperature in Frittenden also marked the first time since 2012 the UK has reached 30C in May, according to the Met Office.

  • Why Michigan is emerging as one of America’s worst-hit climate states

    The state saw 33 tornadoes last year and severe flooding as researchers say links to climate change are undeniable

    The tornado hit west Ann Arbor at 1.45am on 15 April, passing through Veterans Memorial park, where it knocked several mature oak trees and ripped up baseball field fences before setting its sights on a local ice rink.

    “It came up through the parking lot and, in that time, the pressure differential between the tornado and the air inside the rink collapsed the wall,” said Scott Spooner, a manager at Ann Arbor Parks and Recreation.

  • Could nature itself hold the solution to climate change?

    Technological interventions face huge financial or practical challenges, but there is another way

    In 2019, my scientific research was nearly brought to an early end when my team and I published the bombastic statement that natural forest restoration was the “best climate change solution” available in a paper for the peer-reviewed journal Science.

    I remember a colleague from the World Wildlife Fund advising me that this message represented career suicide. He argued that people would be furious because reducing greenhouse gas emissions was the most urgent priority. The revival of nature might help with 30% of our carbon drawdown needs, but you cannot stop rising temperatures without cutting emissions.

  • Endangered sawfish at risk from plan to double water extraction from WA’s Fitzroy River, advocates say

    The Martuwarra Fitzroy catchment is home to four of the world’s five sawfish species, which rely on large groundwater-fed pools to survive the dry season

    Conservationists fear a government plan to double groundwater extraction from the Martuwarra Fitzroy River catchment in Western Australia could jeopardise threatened sawfish populations.

    The untamed river, which flows 700km through the Kimberley to King Sound, is considered the last stronghold for sawfish globally and is home to four of the world’s five species.
