United Nations News Centre - Countries urged to prioritize protection of pollinators to... - 0 views

  •  
    Bees, butterflies and other pollinators are increasingly under threat from human activities and countries must transform their agricultural practices to ensure global crop production can meet demand and avoid substantial economic losses, the United Nations Conference on Biological Diversity heard today. According to the global assessment on pollinators produced by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), 75 per cent of our food crops and nearly 90 per cent of wild flowering plants depend to some extent on animal pollination, which is the transfer of pollen between the male and female parts of flowers to enable fertilization and reproduction. Without pollinators, crops such as coffee, cacao and apples would drastically suffer, and changes in global crop supplies could increase prices to consumers and reduce profits to producers, resulting in a potential annual net loss of economic welfare of $160 billion to $191 billion globally.

General Mills, NGOs Speak for the Bees: Pollinators Need Help From Companies | Sustaina... - 0 views

  •  
    An estimated 3,300 acres on oat farms that supply oats for Honey Nut Cheerios will soon provide new dedicated, flower-rich habitat for pollinators. General Mills is partnering with the Xerces Society, a pollinator and wildlife conservation organization, to plant wildflowers on the supplier farms. Meanwhile, The Wildlife Habitat Council released a white paper explaining the issue of pollinators' decline and actions corporations can take to help.

Lowe's to eliminate pesticides that hurt crop pollinating honeybees | Reuters - 0 views

    Home improvement chain Lowe's Cos Inc will stop selling a type of pesticide suspected of causing a decline in honeybee populations needed to pollinate key American crops, following a few U.S. retailers who have taken similar steps last year.

This Is What Dessert Would Look Like Without Bees - 0 views

  •  
    Bad news for those with a sweet tooth: the absence of pollinators such as bees and butterflies would signal the end of dessert as we know it. Whole Foods Market recently removed all products from an area of the supermarket reliant on the creatures, mirroring past initiatives in the diary aisle and the produce section. The results, seen above in the bakery department for the company's Share the Buzz campaign, are dramatic.

Researchers say Earth is entering a sixth mass extinction event - 0 views

  •  
    As ever more species face extinction, we lose the vital ecosystem services they provide, such as honeybee crop pollination. For its continued existence, mankind is reliant upon an untold plethora of species that maintain the status quo. As they disappear, that existence becomes increasingly fragile.
