Otrovi protiv štetočina nisu efikasni!

Baš kao što se problemi sa komarcima neće riješiti insekticidima, tako ni štetočine nikako nisu kontrolirane uporabom otrova.

Već dugi niz godina se otrov za štakore dostavlja u kućanstava diljem otoka u sasvim neadekvatnim vrećicama od celofana. Da stvar bude još gora, upute su unutra, tako da, ako ih želite pročitati, morate rukovati sa otrovom. Još nezgodnije je stranim vlasnicima kuća, koji ne znaju Hrvatski. Tako se može dogoditi i to, da je jedan stranac bijelu tabletu unutar pakiranja sa crvenim granulama smatrao protuotrovom. Srećom, nije bilo potrebe, da je upotrijebi, jer je tableta zapravo poseban otrov namijenjen za septičke jame, i naravno, ne sadrži nikakav protuotrov. Protuotrov za ove granule je vitamin K.

Upozorenja o isporučivanju otrova su rijetkost. Iako službene web stranice Starog Grada uvijek prenose obavijesti ovog tipa, u ostalim mjestima na otoku to nije slučaj. U Pitvama se obično, dan-dva prije zalijepi mala obavijest na kontejner.

Međutim, tijekom 2016. godine je došlo do poboljšanja situacije u Jelsi, gdje se upozorenja prenose kroz web stranicu Općinskog Vijeća, kao i kroz njihovu oglasnu ploču.

Po zakonu moraju vitamini biti pakirani na siguran način, ali čini se, da otrovi za štakore ne moraju. Ovaj neodgovoran i opasan običaj se nije promijenio niti ulaskom zemlje u Europsku Uniju. Vrećice se ostavljaju naizgled nasumice u mjestima po otoku. Događalo se, da sam ih pronalazila na različitim mjestima: kod prozora kuće, viseći iz mog poštanskog sandučića, čak i na svom autu! Način dostave je očito vrlo neodgovoran. Jesu li ali otrovi korišteni na odgovoran način? Najčešće se jednostavno postave u manjim količinama oko kuće, čak i tamo gdje mogu biti opasni za kućne ljubimce ili malu djecu. Najsigurniji način postavljanja takvih otrova - ako osjećate, da baš morate koristiti takve otrove - je upotrijebiti čvrstu cijev sa rupama za ulazak i izlazak, koje su dovoljno velike za miševe ili štakore, ali su premale za sve druge životinje.

Dok štetočine unutar zgrada sasvim sigurno predstavljaju problem i moguću opasnost za zdravlje, isto se ne može reći za miševe i štakore u divljini, koji imaju svoje mjesto (ako ništa drugo) u prirodnom prehrambenom lancu. Za bolji uvid u njihov način života, pogledajte video u nastavku, ili kliknite ovdje.

S obzirom na redovite doze otrova, štakori postaju otporni, stoga otrov nije rješenje. S druge strane, iako otrov ne bi trebao privlačiti druge životinje, ipak se to događa i nekoliko mačaka i pasa je već smrtno stradalo od otrova. Stvarno tužno i štetno, jer su mačke one, koje drže štakore i miševe, čak i zmije pod kontrolom. Za bilo koju veću pojavu štakora je najbolja metoda za izbjegavanje problema otpornosti na otrove pustiti upornog psa (kao što je Jack russelov terijer), da ih lovi ili koristiti zamke.

Lokalne vlasti moraju potrošiti značajan iznos na distribuciju tih otrova. Gledajući financijsko izvješće Općinskog Vijeća iz 2015. godine, nisam uspjela identificirati točan iznos potrošen na kampanju protiv štetočina i insekata, jer ove stavke nisu navedene pojedinačno. Troši li se taj novac na pametan način? Mislim da ne.

U Velikoj Britaniji su otrovi protiv štetočina dostupni, ali ne distribuiraju se na veliko kroz lokalne vlasti. Distribuirali su se (i možda se to još uvijek tako radi) samo na zahtjev. Prije nekih šezdeset godina, dok smo živjeli nedaleko Londona, moj brat, sestra i ja smo jednom po povratku iz škole pronašli neoznačenu staklenku na kuhinjskom stolu. Moja, po naravi neustrašiva sestra je navalila na staklenku i kako joj se okus činio "sirast", nastavila je jesti, da umanji svoju glad. Nismo imali pun frižider u onim danima, doduše nismo uopće imali frižider i ostava je bila prazna. Međutim, brat i ja smo bili oprezniji te smo odbili njezinu ljubaznu ponudu, da sa nama podjeli sadržaj staklenke. Možete zamisliti horor, koji je doživjela naša majka po povratku sa posla, kada je pitala za staklenku sa otrovom za štakore. Sestra je provela noć u bolnici, gdje su joj kroz pošteno ispumpavanje želuca spasili život. Mislim, da je to bilo zadnji put, da su iz općine ostavili neobilježen otrov za štakore u nečijem domu u nevino izgledajućoj, neosiguranoj staklenci.

Na Hvaru sam poslijednih godina uspjela zaustaviti isporuke otrova postavljanjem obavijesti na svojoj kući. Jednostavan natpis: "Otrov, ne hvala" preporučujem svima, koji ne žele biti opterećeni rukovanjem ili skladištenjem opasnih stvari.

Nekontrolirana distribucija otrova je očito opasna. Uz činjenicu, da otrov nije učinkovit postupak za suzbijanje štetočina, ovaj način postupanja je potrebno razmotriti i potrebno je trenutnu praksu znatno poboljšati - kao stvar od iznimne hitnosti.

  • UK opening new oil and gas fields would imperil global climate goals, experts say

    Senior climate figures warn North Sea drilling would encourage fossil fuel exploitation by developing countries

    Opening new oil and gas fields in the North Sea would “send a shock wave around the world”, imperilling international climate targets, undermining the UK’s climate leadership and encouraging developing countries to exploit their own fossil fuel reserves, experts have warned.

    The UK government is under stiff pressure from the oil industry, the Conservatives, Nigel Farage’s Reform UK party, some trade unions and parts of the Treasury to give the green light to new oil and gas fields, despite clear evidence that doing so would not cut prices and would have almost no effect on imports.

  • Campaigners demand action to break UK’s ‘addiction’ to controversial herbicide

    Use of glyphosate has risen 10-fold in 30 years, raising fears for public health

    It was Scottish farmers in the 1980s who pioneered the practice of spraying glyphosate on their wheat just before harvest. Struggling in the damp glens to get their crop to dry evenly, they came up with the idea of accelerating the process by killing it a week or two before harvesting.

    Glyphosate, then a revolutionary herbicide that killed everything plant-based but spared animal life, seemed perfect for the job. Soon the practice spread to wetter, colder agricultural regions around the world.

  • Country diary: There’s a pecking order to my bird feeder – but should I be feeding them at all? | Gwyneth Lewis

    Cardiff: Robin then blue tit, siskin then goldfinch … I love this ritual, but I’m persuaded that it deserves more careful thought

    I’ve been away from my bird feeder for months and, on my return, one of my priorities is to restock it. This has become a ritual, and I feel great joy in observing the strict order in which the birds arrive.

    I sit down and wait for the local population to remember my table and spread the word. It’s not long before they come in sequence, no less predictable than court etiquette. The first to venture for sunflower seeds is the robin. The blue tit, in a whirr of wings, comes a close second. These two act as food tasters. Other species, out of sight, watch intently to see if the daring survive. They do, so dunnocks arrive, then a pair of chaffinches, picking up spilt seeds from the ground.

  • ‘Should it all just be renationalised?’ – your water crisis questions answered

    Sandra Laville has been reporting on England’s sewage crisis for years. She answered your questions on the water privatisation scandal.

    Guardian environment correspondent Sandra Laville’s reporting on the sewage crisis in English water has helped to expose a scandal of privatisation that has created a swell of fury across the political divide.

    Sandra has now finished answering your questions. Read the Q&A below.

    The government has put the cost of renationalising water at £100bn. But this is a disputed figure. Academics working with the People’s Commission on the Water Sector say this figure is ‘serious scaremongering created on biased evidence’ which was paid for by water companies. It is based on the Regulatory Capital Value of companies as determined by Ofwat, not the” true and fair value in law”, which reflects losses from market failures, like the cost of pollution or the monopoly profits taken by shareholders and banks.

    The route to renationalisation could come via the system set up legally when the companies were privatised. Under the law companies can be put into special administration if they are unable to pay debts, if they breach licence obligations, such as on sewage pollution, or failing to supply water, and if it is considered in the public interest to do so. Special administration is a form of temporary renationalisation.

    This is the million dollar question! While tackling separation across the whole network at once is considered too disruptive and costly, particularly in urban environments, the chartered institute of water and environmental management says moving towards separated systems is their key focus to address urban pollution and storm water sewage releases. New developments, for example, are now mandated to have separate pipes for foul wastewater and surface water run off.

    They also want to see the increased use of sustainable drainage systems like water butts, and storage basins for existing properties, to reduce the amount of runoff into the system. Keeping gardens rather than paving them over, and creating so called sponge cities is also key to tackling pollution.

    The UK was described as the dirty man of Europe back in the 70s and 80s, due to levels of pollution. For example in coastal towns there were no water treatment plants to treat sewage, raw sewage was just pumped and dumped into the sea. It was only when the EU directives came in that the clean up began. Chief amongst these was the Urban Wastewater directive, the Water Framework directive, and the Bathing Water directive.

    Since leaving the EU there have been fears that these pieces of legislation could be watered down. James Bevan, as CEO of the Environment Agency, talked about changing the Water Framework Directive, essentially to make it easier for rivers to pass tests for chemical and biological health. Currently no river is rated as in good overall health under the WFD where rivers have to pass both chemical and biological health tests.

  • Say no to pesticides, mix up your lawn – and six more ways to help bees to thrive

    Like so many flying insects, these essential pollinators are suffering because of habitat loss and the overuse of chemicals. Here’s how to give them a healthier, happier home

    We know about honeybees and bumblebees, but most of the UK’s bees are neither: they’re solitary bees, loners who come in a dizzying range of sizes, colours and varieties – more than 240 species. Have you heard, for instance, of the hairy-footed flower bee? “They’re one of the first bees to emerge each year,” says Laura Larkin, the chief conservation officer at Buglife. “The males have got fantastic little fluffy bits on their feet.”

    How about leaf-cutter bees, which chomp “a perfectly circular hole” out of leaves to build their nests? Or bright-orange tawny mining bees, wool-carder bees, ivy bees? “There are so many of them and I’m still learning,” says Kate Bradbury, a wildlife gardener, writer, bee lover and the author of One Garden Against the World. “They’re just great – there’s a solitary bee for every occasion.”

  • ‘The water is no longer our friend’: how dredging is pushing Lagos Lagoon towards ecosystem collapse – photo essay

    Taking sand from the Nigerian city’s lagoon to supply a building boom harms more than fish – it affects the entire food chain, erodes coastlines and is depriving fishing communities of their livelihoods

    Before dawn, when the noise of Lagos’s danfobusesfills the air and generators rumble to life, the city’s lagoon is already stirring. Not from fish splashing or canoes gliding, but from the long suction pipes of the dredging machines, pulling up the lagoon bed and spitting out wet sand that will be used in the construction of high-rise blocks, housing estates and flyovers.

    Sand dredging is regulated by the Lagos state government and the waterways authority but in a city of more than 20 million people, where sharp sand has never been in higher demand, not all dredging is being done by the book.

    Dredging leaves its mark on the landscape along the shores of the Lagos Lagoon in Epe

  • Oil slick from bombed Iranian ship threatens protected wetland

    Shahid Bagheri leaking fuel towards Hara mangrove forest, home to migrating birds and endangered turtles

    An oil slick from a stricken Iranian ship threatens to contaminate one of the Middle East’s most important wetlands, satellite image analysis suggests, making it one of a number of spills posing a risk to the livelihoods of coastal communities in the Gulf.

    The Shahid Bagheri, a drone carrier, began leaking heavy fuel oil in Iranian territorial waters near the strait of Hormuz after it was hit by a US warplane in the first few days of the US-Israel attack on Iran.

  • Bitten by snakes 200 times – on purpose: US man’s quest to help deliver new antivenom

    Tim Friede put his ‘ass on the line’ to help stop snakebite deaths – whose numbers appear to be rising amid the climate crisis

    As we overheat and degrade our planet, more people are set to come into contact, sometimes fatally, with venomous snakes. One man hopes to provide an unusual solution to this, after subjecting himself to 200 intentional snakebites to his body.

    For nearly 20 years, Tim Friede, 58, allowed some of the most lethal snakes in the world to bite him so he could build up an immunity that could one day be developed into a universal antivenom.

  • ‘They poo all over the yard’: little corellas are terrorising Kangaroo Island – and nothing can stop them

    The birds – not native to the South Australian island – have covered a school in faeces, torn up infrastructure and damaged crops

    Thousands of little corellas that have been terrorising the inhabitants of Kangaroo Island have been culled but it won’t be enough to fix the problem, authorities say.

    The birds, which are not native to the island, have covered a local school in faeces, torn up infrastructure, damaged crops and caused mental distress to residents with their screeching.

  • As Iran war exposes global dependence on fossil fuels, the biggest emitters are reaping the rewards

    Worst polluters hold world’s future in their hands as they benefit from higher fossil fuel prices, but global trends favour renewables

    Oil stands at about $110 a barrel and some forecasts have predicted it could reach $150. Food prices are on the rise and are expected to leap further owing to the fertiliser supply crunch, leading the World Food Programme USA to warn that global food insecurity could reach record levels, with 45 million more people pushed into acute hunger. Industries from steel to chemicals have alerted markets that they face shortages and soaring costs, while households across the world are feeling the pinch – people have been told to turn down their thermostats, take the bus or cycle, and cut their speed on motorways.

    The impact of the US-Israel war on Iran – the third global shock in six years, after Russia’s full-scale invasion of Ukraine and the Covid-19 pandemic – has laid bare how reliant our economies still are on fossil fuels. Simon Stiell, the UN climate chief, said in March: “Fossil fuel dependency is ripping away national security and sovereignty and replacing it with subservience and rising costs.”
