How animal waste is helping turn China's lakes green

Animal husbandry is contaminating China's water and has been linked to bright-green lakes, a phenomenon know as eutrophication. More here.

Bad News for Crops! Global Warming = More & Hungrier Bugs!

Crop losses for critical food grains will increase substantially as the climate warms, as rising temperatures increase the metabolic rate and population growth of insect pests, according to new research. More here.

Most harm will befall crops in the temperate zone (shown in green). 

The more pesticides bees eat, the more they like them

Bumblebees acquire a taste for pesticide-laced food as they become more exposed to it, a behaviour showing possible symptoms of addiction. More here.

How does agriculture affect vulnerable insect-eating birds?

The American Ornithological Society

Aerial insectivores--birds that hunt for insect prey on the wing--are declining across North America as agricultural intensification leads to diminishing insect abundance and diversity in many areas. A new study from The Condor: Ornithological Applications looks at how Tree Swallows' diets are affected by agriculture and finds that while birds living in cropland can still find their preferred prey, they may be working harder to get it. More here.

Officials Worry Yet Another Lethal Pig Disease May be Coming to Canada

by Larry Powell

The Manager of the "Canada West Swine Health Intelligence Network" warns, now that African Swine Fever (ASF) has been confirmed in China, the risk of it spreading to North America, has increased. 

Dr. Jette Christensen, veterinary epidemeologist.

Dr. Jette Christensen (above) describes ASF as "a serious and trade-limiting viral infection." Speaking on the industry-sponsored radio program, "Farmscape," she assured listeners, if  the Canadian industry follows import regulations, "they should be safe." But she also warns that the virus can survive for months outside the host in pork products.

Dr. Christensen warns Canadian producers, that workers they hire, could bring the disease home with them after vacationing in China or Eastern Europe. And they should even be careful when bringing in exchange students, for the same reason.

AFS does not affect humans, so is not considered a food safety concern. But it is described as one of the deadliest diseases of pigs.

The World Health Organization warns that crowded, confined and intensive livestock"factories" (used widely in Canada and around the world), increase the risk of such infectious diseases. 

Delia Grace Randolph, veterinary epidemiologist.

And, in the words of Delia Grace Randolph of the International Livestock Research Institute (above), "The evidence seems quite clear that intensification, especially of pigs and poultry, is associated with emerging infectious zoonotic disease, foodborn disease and antimicrobial resistant pathogens."
