Cientistas querem criam gado que não arrote!

Por incrivel que pareça, dos gases enviado para a atmosfera, alguns são provenientes de arrotos do gado, e cientistas querem arranjar maneira de combater esse facto... aqui vai o texto:

"The agriculture sector is the nation's second biggest source of greenhouse gas emissions behind the energy sector, producing about 16 per cent of Australia's total emissions, The Sunday Mail reports.
Two-thirds of that figure is produced by livestock, and 66 per cent of those emissions are released as methane from the guts of grazing livestock such as sheep and cattle.
Australia’s Sheep Co-operative Research Center is conducting a world-first study into 700 sheep with 20 different genetic lines – each is fed, then shepherded into a booth where scientists measure their burp outputs.
One study leader, Dr Roger Hegarty, said sheep burped large amounts of methane and there was environmental pressure to see whether that could be minimized.
"We're looking into how to reduce emissions from sheep – all over Australia teams are testing different approaches: changing the microbes in the gut, changing their diet, or changing the genetics of the animal," he said.
"Our sheep studies are (primarily) aiming to find out if there is genetic control over methane production and, if so, is that a good thing to pursue?"
Dr Hegarty said researchers were wary not to produce other problems in their bid to reduce the animal's carbon footprint.
"Methane is the exhaust from livestock, and – just as you can't put your hand over the exhaust pipe of a car and expect it to keep running – we're treading carefully to reduce emissions without causing other problems," he said."

  1. Gostei desta ideia... esta bicharada são os porcos que não só arrotam, como ainda por cima faz mal ao ambiente!

  2. bem algo invulgar sem dúvida! imaginem a quantidade de gado que pra ai anda arrotar e a poluir o ambiente!!! e os outros gases não são nocivos também? lol
