    Study Notes

    Importance of Honey Bees

    • One out of three meals eaten by humans is made possible by honey bees
    • If all honey bees were to die out, thousands of plants would follow, leading to millions of people starving
    • The dollar value of plants pollinated by honey bees each year is around $265 billion
    • Food that would be affected by the loss of honey bees includes apples, onions, pumpkins, and plants used for feeding livestock (milk and meat)

    Threats to Honey Bees

    • Millions of hives have died in the last few years, with annual losses of 30-90% of colonies
    • "Colony collapse disorder" has affected honey bees in many countries since 2006
    • Parasites such as Acarapis woodi and Varroa destructor have invaded honey bee colonies
    • Varroa destructor reproduces in honey bee hives and feeds on the bodily fluids of bees, weakening them and spreading viruses
    • Neonicotinoids, a chemical family similar to nicotine, are deadly to bees and have been used extensively in agriculture since the 1990s
    • Neonicotinoids harm bees in various ways, including causing convulsions, paralysis, and death, and impairing their ability to navigate

    Contributing Factors to Bee Decline

    • Genetic uniformity in bee populations
    • Crop monocultures
    • Poor nutrition due to overcrowding
    • Stress caused by human activities
    • Other pesticides

    Consequences and Solutions

    • The demise of honey bees would be a catastrophe for human food production and diversity
    • Humans need to take better care of their surroundings to ensure the survival of honey bees and other lifeforms
    • An alternative to neonicotinoids is urgently needed, but the chemical industry is delaying this by sponsoring studies that downplay the toxicity of these chemicals to bees

    Importance of Honey Bees

    • One-third of human meals rely on honey bees for pollination
    • Honey bees' extinction would lead to widespread plant extinction and massive food shortages, affecting millions of people
    • The annual value of honey bee-pollinated crops is approximately $265 billion
    • Fruits and vegetables that would be affected by honey bee loss include apples, onions, pumpkins, and livestock feed

    Threats to Honey Bees

    • Honey bee colonies have experienced devastating losses, with annual losses ranging from 30% to 90% of colonies
    • Colony collapse disorder has plagued honey bees globally since 2006
    • Parasites like Acarapis woodi and Varroa destructor have invaded honey bee colonies
    • Varroa destructor reproduces within hives, weakening bees by feeding on their bodily fluids and spreading viruses
    • Neonicotinoids, a nicotine-like chemical, have been extensively used in agriculture since the 1990s and are toxic to bees
    • Neonicotinoids cause bee convulsions, paralysis, death, and impair navigation

    Contributing Factors to Bee Decline

    • Genetic uniformity in bee populations contributes to their vulnerability
    • Crop monocultures reduce bee diversity and nutrition
    • Overcrowding leads to poor bee nutrition
    • Human activities cause stress that affects bee health
    • Other pesticides also harm honey bees

    Consequences and Solutions

    • The extinction of honey bees would have catastrophic consequences for global food production and diversity
    • Humans must take responsibility for their environment to ensure the survival of honey bees and other species
    • An alternative to neonicotinoids is urgently needed to protect honey bees
