Can food production keep pace with demand?
Cuts in research threaten ability to keep pace with growing demand
FRISCO — A top food expert says the world could be facing a serious food shortage in 40 years, when production won’t be able to keep up with growing demand.
“For the first time in human history, food production will be limited on a global scale by the availability of land, water and energy,” said Dr. Fred Davies, senior science advisor for the U.S. Agency for International Development. “Food issues could become as politically destabilizing by 2050 as energy issues are today.” Continue reading

Silver nanoparticles used in food packaging and many other common products may trigger over-production of disease-causing free radicals in cells.
‘We can confirm that nano-silver leads to the formation of harmful, so called free radicals in cells …’
FRISCO — Nano-engineered particles may help help boost the efficiency of solar power generation and improve pesticides, but they also present threats to the environment and human health.
Researchers in Denmark say silver nanoparticles can penetrate human cells and cause damage. Silver nanoparticles are used by the food and cosmetics industries because of their antibacterial properties. The particles can be found in drinking bottles, cosmetics, band aids, toothbrushes, running socks, refrigerators, washing machines and food packaging. Continue reading

‘The real value of antibiotics is saving people from dying. Everything else is trivial’
By Summit Voice
FRISCO — Massive use of antibiotics for food production is only marginally beneficial and poses a huge long-term risk to human health, researchers in Canada say. In a new paper, the scientists proposed a user fee that could help curb excessive application antibiotics in the agriculture and aquaculture industries.
The new paper published in the New England Journal of Medicine explains that in the United States 80 per cent of the antibiotics in the country are consumed in agriculture and aquaculture for the purpose of increasing food production.
The flood of antibiotics sprayed on fruit trees and fed to livestock, poultry and salmon has led bacteria to evolve. Mounting evidence cited in the journal shows how resistant pathogens are emerging — resulting in an increase in bacteria that is immune to available treatments. Continue reading
