Uptake of environmental pollution through consuming contaminated food is concentrated in longer-lived organisms higher in the food chain. For example, killer whales and polar bears are considered some of the most contmainated animals on the planet.

Fewer studies seem to be done on purely terrestrial mammals but it is hard to believe the same principles do not apply. And, yes, there is plenty of evidence that human-cultivated foods can be as polluted as wild foods.

So, the challenge is to find a relatively pollution free place to live and relatively contaminant-free food sources.
