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.

  • Coal use to reach new peak – and remain at near-record levels for years

    Spike in fossil fuel use a result of global gas crisis triggered by Russia’s invasion of Ukraine

    The world’s coal use is expected to reach a fresh high of 8.7bn tonnes this year, and remain at near-record levels for years as a result of a global gas crisis triggered by Russia’s invasion of Ukraine.

    There has been record production and trade of coal and power generation from coal since Russia’s full-scale invasion of Ukraine inflated global gas market prices, according to the International Energy Agency (IEA).

  • Pollution exposure linked to mental health hospital admissions, says study

    Researchers from St Andrews found rise in nitrogen dioxide exposure associated with higher admissions

    Exposure to air pollution is linked to an increased risk of hospital admission for mental illness, according to the most comprehensive study of its kind.

    The research, involving more than 200,000 people in Scotland, found an increase in exposure to nitrogen dioxide in particular was associated with a higher number of people being admitted to hospital for behaviour disorders and mental illnesses.

  • Pakistan and Bahamas join push for global pact to phase out fossil fuels

    Climate-vulnerable pair add weight to proposed treaty seeking transition from coal, oil and gas in equitable way

    Pakistan and the Bahamas have joined a growing bloc of climate-vulnerable countries seeking to broker a global pact to phase out fossil fuels in an equitable way, the Guardian can reveal.

    The Bahamas is the 15th nation to fully endorse the proposed fossil-fuel non-proliferation treaty, which would provide a binding global roadmap to explicitly halt expansion of coal, oil and gas in a fair way – with wealthy nations responsible for the highest emissions transitioning first and fastest.

  • ‘Ridiculous’ ban on exotic animal skins at London fashion week criticised by experts

    Trade can help protect species – and real skins are often more sustainable than synthetic alternatives, say conservationists

    Conservation experts have criticised a decision by London fashion week to ban exotic animal skins from its 2025 shows as “ridiculous”, warning that it is ill-informed and could harm the protection of many snakes, crocodiles and reptile species.

    Last month, the British Fashion Council’s deputy director for policy and engagement, David Leigh-Pemberton, told parliament that next year’s fashion shows would prohibit the use of skins from alligators, snakes and other animals. In a statement, the council said the ban was part of a wider range of standards to promote sustainable practices in the fashion industry.

  • ‘Dark day for New Zealand’: outcry as bill to fast-track controversial mining projects is approved

    Critics and opposition parties vow to oppose major projects they fear could damage the environment

    A new law that could see controversial mining and infrastructure projects fast-tracked for approval across New Zealand has sparked protests in parliament and vows from critics and opposition parties to stop proposals that they fear will wreak havoc on the environment.

    The coalition government’s Fast-Track Approvals legislation passed into law on Tuesday, despite thousands of public submissions opposing it.

    Southill, Bedfordshire: On a ringing session of seed-eating farmland birds, I see up close the subtle beauty of the yellowhammer

    We’ve just released a second blitz of tits, when we notice that the mist net along the field edge has caught a sunbeam. The cold orange light that spilt over the horizon at dawn and pooled above the fields is long gone; the teasel, knapweed and bristly oxtongue seedheads are no longer haloed with hoarfrost. Instead, they’re drawing ground-feeding birds down to forage among the wild grasses and flowers.

    The fallow fields around us are part of an ambitious project to restore ecosystems across more than 1,500 acres of the Southill Estate. The plan includes creating new ponds, allowing land to revert to native scrub, and planting woodland for coppicing. Today’s visit is one of a series of winter ringing sessions to monitor the birds flocking to the fields. I’ve tagged along with my dad (a licensed ringer) and Suzy (a trainee). Their primary aim is to record seed-eating farmland species, many of which – such as greenfinch and corn bunting – are on the UK red list. And we’re in luck. Linnets lurk in the scrub and tinklings of goldfinches pass overhead.

  • ‘If 1.5m Germans have them there must be something in it’: how balcony solar is taking off

    Balcony solar panels can save 30% on a typical household’s electricity bill and, with vertical surface area in cities larger than roof space, the appeal is clear

    They are easy to install, and knock chunks off electricity bills. It may not be Romeo and Juliet, but Spain’s balcony scene is heating up as the country embraces what has hitherto been a mainly German love affair with DIY plug-in solar panels.

    Panels have already been installed on about 1.5m German balconies, where they are so popular the term Balkonkraftwerk (balcony power plant) has been coined.

  • Can everyone eat for the planet? I shopped at Dollar Store for a week to find out

    In 2019, scientists published a climate-friendly food plan. I’ve long wondered: could it work for most Americans?

    As a fossil fuels and climate reporter, most of my journalism focuses on the need to radically overhaul the energy system. But the food sector also needs a makeover, as it creates between a quarter and a third of all greenhouse gas emissions.

    When scientists came up with a new climate-friendly food plan in 2019 and published their findings in the medical journal the Lancet, I read with interest. The guidelines called for more vegetables, legumes and whole grains, which seemed doable to me. The authors even allowed for meat and dairy consumption, albeit in small quantities. Both are major drivers of the climate crisis: the United Nations estimates that meat and dairy produce more than 11% of all global greenhouse gas emissions, and some experts put the figure at up to 19.6%.

  • Bamboo bonanza: how a village in India used its forest to go from poverty to prosperity

    Restoring age-old land rights has enabled 300 villagers to build a profitable business and halt the exodus to the city

    It’s late morning and the sound of axes clacking against wood echoes through Pachgaon’s bamboo forest in the central Indian state of Maharashtra. A huge depot, larger than a cricket stadium,is full of bamboo branches, stacked neatly by size in different sections. Nearby is a small, windowless office painted in the colours of the forest – a record-keeper of Pachgaon’s turnaround from abject poverty to relative wealth in just over a decade.

    Pachgaon’s rags-to-riches story follows the implementation of two longstanding Indian laws that restored to the local adivasi (tribal) community its traditional ownership rights over the forest, which they lost to rulers and colonisers several generations ago.

  • Can Colombia’s ‘crazy’ cattle ranchers make beef an eco-friendly choice?

    By rejecting traditional grazing and maintaining trees and wildlife habitats alongside pasture, farmers are turning their land carbon positive. But will it be enough?

    On a humid dawn in Colombia’s livestock capital, Michael Robbin rides across one of his farm’s pastures, where tall green stalks brush his horse’s belly. When he bought the land outside Montería in 2020 he divided it into 125 smaller fields. His neighbours called him crazy at first.

    “That’s not how it’s done in this area,” he acknowledges. “Everybody was looking at me like I was from outer space.”

    U našem dijelu svijeta, koji zovemo zapadnim i smatramo razvijenim, prije samo 50 godina nisu sve žene imale pravo glasa na izborima, nisu imale jednak pristup obrazovanju, nisu mogle voditi države i nisu imale pristup visokim pozicijama u poslovnom svijetu.

  • O ciljevima održivog razvoja: Cilj 14. Oceani, mora i morski resursi

    Gotovo svi su upoznati s činjenicom kako oceani i mora prekrivaju više od 70 % površine Zemlje. Me?‘utim, nedovoljno je prepoznato kako su oceani, mora i obalna područja esencijalni dio Zemljinih ekosustava te kako o njima ovisi cijelo čovječanstvo, bilo na obali ili u dubokoj unutrašnjosti kontinenata! Zašto?

  • O ciljevima održivog razvoja: Cilj 12. Održiva proizvodnja i potrošnja

    Ovaj cilj održivog razvoja odnosi se na ostvarivanje održive proizvodnje i potrošnje u čemu trenutačno ne uspijevamo jer je ekološki otisak koji ostavljamo i dalje ve?‡i od resursa koje imamo na raspolaganju. Dakle, potrebno je promijeniti načine na koji proizvodimo hranu, smanjiti bacanje hrane, pove?‡ati udjele obnovljive izvore energije u ukupnoj proizvodnji energije, pravilno gospodariti otpadom tijekom čitavog njegovog životnog ciklusa kako bi, me?‘u ostalim što manje utjecali na zaga?‘enje zraka, vode i tla.

  • O ciljevima održivog razvoja: Cilj 9. Infrastruktura, industrija, inovacije

    Razvoj industrije i infrastrukture kao temelja za pove?‡anje životnog standarda za sve ljude, uz okolišno prihvatljiva rješenja te uključivanje novih tehnologija tema je cilja održivog razvoja koji se odnosi na okolišno prihvatljivu industrijalizaciju, kvalitetnu, pouzdanu, održivu i prilagodljivu infrastrukturu, a sve uz primjenu novih tehnologija, istraživanja i inovacija.
