As a people, we only worry about what we're told to worry about, or what we can see. Nobody forces the question about what we're not seeing, and that is by design. I'd love to see human pharmaceutical residue tests on waterfowl. I shake my head when I drive by water treatment ponds and see them full of ducks and geese bathing and eating in water full of human drugs.
Grant woods did some videos on neonics in turkeys and the livers of deer. I caught a podcast once talking about pesticide buildups in bears, despite them being entire regions away from agriculture. Over the life of a bear, those pesticide dusts move entire regions and deposit into regions that never asked for those things.
Nobody measures amoxicillin buildup in pork. Nobody measures the toxic levels of omega 6 to omega 3 ratios in confinement meats and their effects on the human body vs meats that have natural ratios of omega 6 to 3. Nobody measures the absence of nutrients in chickens that reach slaughter size in 6-8 weeks in a house, vs slow chickens designed by god that live outside and eat bugs and walk around and can live for years vs dying of obesity at 12 weeks.
What are the human health effects of eating meat of animals that were weeks away from death caused by inflammation, vs healthy free ranging herbivores? I know all these answers because I went looking for them.
