KOMARCI I DEZINSEKCIJA

Objavljeno u Vaša pisma

U Jelsi i okolnim mjestima, već po dva puta je obavljeno prskanje protiv komaraca, i uskoro će biti još toga.

Rezultat prskanja jednak je nikakav, jer komaraca ima jednako kao i prije. Ubadaju i danju i noću, nemoguće je tijekom dana u vrtu boraviti nekoliko trenutaka a da vas ne napadne roj komaraca. Ali prskanje je ipak polučilo rezultat, tako da nema pčela, osa, leptira ni muha. Nisam sigurna da su spomenuti kukci bili ciljana skupina. No nisu sami ti kukci nestali. Nema ni ptica koje bi ranom zorom svojim pjevom često budile ljude. U mojem vrtu godinama je obitavala porodica kosova. I u proljeće su bili tu i hranili svoje mladunće. A onda su nestali, poslije prvog prskanja protiv komaraca. Nadam se da se „otselili“ u čistiji okološ, a ne da su stradali od „neopasnog“ otrova koji je navodno otrovan za kukce, ali ne i za toplokrvne životinje. Jer danas sam vidjela uginulog kosa koji očito nije imao sreće.

 

Da otrov ne djeluje na komarce vidimo svakodnevno, ali ako bar malo obratimo pažnju na prirodu oko sebe, vidjet ćemo da djeluje na druga stvorenja. A otrovi ne nestaju, ne rastvaraju se na vodik i kisik pa da kao voda jednostavno ispare u zrak. Nego se lijepo pomalo talože u zemlji, biljkama, životinjama, pa i nama ljudima. A struka kaže da to nije opasno, da su to male količine. A koliko tih malih količina rarnoraznih otrova svakodnevno ulazi u nas kroz hranu, zrak, vodu? A kao jedini odgovor nudi nam se tvrdnja da tako mora biti, jer je to napredak. Zar je to zaista napredak? N., Vitarnja, email 31.08.2014.

  • A ‘reasonable worst-case scenario’ suggests need for large-scale movement of populations away from reshaped coast

    Up to 13 million people in the UK face the long-term risk of coastal flooding due to the climate crisis, scientists have warned, with a “reasonable worst-case scenario” suggesting the need for the large-scale movement of populations away from a dramatically reshaped coast.

    Even if today’s global pledges to cut carbon pollution are met, about 1.4 million more people will be exposed to coastal floods in 2200 and 1.7 million in 2300 due to the sea level rise driven by melting ice caps and warming oceans.

  • Puffling excites volunteers trying to save the last known regular nesting site on mainland of southern England

    For years, volunteers have craned their necks and tested their patience to peer into the crevices of the cliffs hoping for a glimpse of fluffy joy.

    Finally it all paid off as a puffling – baby puffin – poked its way into the sunshine, becoming the first to be spotted on the coast of Dorset in southern England for three decades.

  • Greenpeace petitions Dutch courts to order JBS to disclose how its aims are compatible with responsibilities to climate and human rights

    The world’s biggest meat company, JBS, faces a landmark legal challenge to disclose how its $6bn (£4.5bn) global expansion plan is compatible with responsibilities to the climate, nature and human rights.

    Courts in the Netherlands, where JBS is headquartered, will assess the petition filed by Greenpeace for information on whether the company is compliant with Dutch laws on “duty of care” as well as its own publicly stated commitments.

  • Neso denies allegations aired by Tory MP that staff took part in cover-up over decision-making in heatwave

    In a control room in Wokingham, Berkshire, staff work around the clock, minute by minute, to align Great Britain’s fluctuating power supplies with its ever-changing demand.

    However, as households struggle to adapt to soaring summer temperatures, staff at the government-owned National Energy System Operator (Neso), tasked with keeping the lights on, have faced the kind of challenge usually reserved for the country’s coldest winter nights in recent weeks.

  • Whales flown to US aquariums after long-running saga in which Marineland had threatened to euthanise them

    Six beluga whales have at last left Marineland, the embattled Canadian marine park in Niagara Falls that previously threatened to kill its own animals, and are arriving at US aquariums this week.

    While the whales’ journey into the US marks the end of their long and controversial saga of captivity in Canada, advocates say the new conditions, though superior to Marineland, could bring continued challenges.

  • Trevone Bay, Cornwall: The odds of survival of these juveniles raised in a hatchery are 1,000 times greater than if they had been born in the wild

    As I tipped the plastic pot, the juvenile lobster edged forwards, seemingly reluctant to take the plunge. Barely a couple of centimetres long, it had been nurtured through the perilous first weeks of life. Now it was free to roam the sea, with all the risks that entailed.

    Shaped like a miniature clothes peg, tiny claws spread wide, it gave a flick of its tail and propelled itself out of the pot and down to the sandy bottom of the rock pool, before disappearing among tangles of seaweed.

  • About 23 million people across country affected by water-saving measures with ‘prolonged dry weather’ in eight areas

    About 23 million people will be banned from using hosepipes by this weekend, as England and Wales moves closer to drought status.

    On Tuesday Thames Water became the latest water company to announce a hosepipe ban, covering the more than 10 million customers it supplies water to across London and the Thames valley.

  • Despite official claims that the São Francisco River project supplies 12m people, many of those who had to make way for its construction in 2007 still have no water at all

    A concrete canal cutting through the Caatinga scrubland feeds a surface reservoir two and a half miles from Maria de Fátima Ferreira da Silva’s home in rural Brazil. The canal passes Sertânia and continues until it reaches Monteiro, the next town along, where it spills its precious cargo into the bed of the Paraíba River – a human-directed inflow into the seasonally dry waterway.

    Such proximity to a reliable water source would usually be considered a blessing in the sertão, a vast outback in Brazil’s north-east known for its punishing droughts. But not for Ferreira, who was displaced nearly 20 years ago by the construction of the canal and now lives in a house without any water supply, despite the nearby reservoir.

  • Portable fans, a ‘cooling necklace’, sun protective hats and more products we reach for when the heat won’t quit

    If you’ve stepped outside lately, you know the heat isn’t letting up. With another round of triple-digit temperatures and heat advisories blanketing parts of the US, we asked our writers to share the things they rely on when summer gets unbearable.

    They shared recommendations for portable fans, a powerful dehumidifier and shorts that keep you cool even after hours of walking. Multiple writers recommended REI’s Sahara hoodie. You’ll also find clever picks you may not have considered, such as reusable ice packs and a “cooling necklace”. Here are our 12 tried-and-true essentials that are keeping us from melting on hot, sticky summer days.

  • Experts share tips to avoid the blood-sucking pests that can transmit Lyme disease and other illnesses on to humans

    I won’t go into gory detail about the tick I found latched behind my ear approximately 35 hours after a hike in early June. Suffice it to say, the parasite was well fed, and I was horrified.

    I am far from alone in making such a disgusting discovery. According to the Centers for Disease Control and Prevention (CDC), emergency room visits for tick bites have been unusually high in the US this year. Thirty-one million Americans are bitten by ticks annually – and the number has been trending up for over a decade. In the UK, ticks appear to be rising in number and species variety.
