Some beekeepers actually mentioned that they've been scraping the beeswax clean off their hives more frequently because its known that the beeswax collects pesticides and herbicides over time which affects the colony due to exposure.
The problem is its not just monsanto acid, there's a ton of other issues also correlated like weather/climate, seasonal flowering, untreated parasites, bacteria, etc.
We've literally nuked the environment so hard that even if we fix one problem, the population will not make a full bounce back (although I would think monsanto is the biggest threat)
Biggest scam of this century was corporate produce monoliths convincing people Organic was about health and not the fact that it doesn't use a scorched earth policy and scam one off hybrid plant seeds to grow food which has been setting us up for a widespread fammine for decades.
Some random superweed is gonna crossbreed with some rapid out of control growth plant and wipe out half of the food chain.
I don't know what the actual reasoning is but the 49/46% on Cambodia and Vietnam sounds an awful lot like how we still embargo Cuba like decades after failing to overthrow Castro.
