People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

Bees, birds may suffer from pesticides

RATE THIS! +10
Posted in Science on 5th Oct, 2014 12:08 AM by AlexMuller

New research published over the summer is posing ever more serious questions about whether neonicotinoids, the most common insecticides in the world, are affecting birds and bees more widely than previously thought. The research is looking into more subtle, long-term effects from the insecticides, rather than instant direct kills, that may still harm bird and bee populations.

 
Through a four-week study on bumblebees, Nigel Raine, an expert in pollinator conservation at the University of Guelph, found that the neonicotinoids, which are neurotoxins, affect bumblebees’ ability to find and collect food.  
 
“When the neonicotinoid-treated bees go out of the colony for the first time to look for flowers, something about their exposure to that pesticide means that they’re less able to collect as much pollen as the bees that are untreated,” he told the CBC Radio program Quirks & Quarks. “And that impact only gets worse over time, because the untreated bees improve their performance and their ability.”
