@Abdullah - sounds like you've got some wonderful honey hookups! Haha. That's awesome
The understanding here in the US on colony collapse is that it may be due to a combination of factors. GMO crops and the cocktails of pesticides and herbicides being used is the likely culprit.
I saw some studies that were circulated by the chemical companies showing tests run on individual chemicals they produce, none of which were killing bees. However - when combined in myriad ways (various chemical pesticides and herbicides) from various companies - colony collapse would ensue.
The takeaway is that Life can most likely metabolize some chemical pollution - but when overloaded and burdened with unknown reactions from near infinite chemical cocktails...that kind of chemical exposure can't be metabolized and leads to collapse.
I think this is in part why there is such a movement ahiftings towards more naturally-minded products of all kinds. Chemicals in isolation aren't as toxic as the countless unknown reactions occurring between the thousands of chemicals in existence today.
Don't quote me on this - I recall seeing somewhere in the ballpark of 80,000+ manmade (not naturally occurring) chemicals in use around the world. Who's good at math? What is the factorial output of 80,000 reactions creating god knows how many unintentional chemicals? When considered...the number is mind numbing, and helps to explain the toxic burden Modern Life has placed upon the very earth and its myriad inhabitants.
Enjoy your honey...it's a true miracle and an increasingly rare miracle!
