Maybe we are poisoning ourselves with something that is also producing
irrationality! There is evidence that animal species associated with humans in the US are also growing fatter. So could it be something in the soil or the air. This is of course a facetious suggestion, but you never know.

Not sure why John thinks that " something is making domesticated animals fatter "
is a facetious suggestion. It is not. Not just antibiotics figure in animal feed, hormones
serve too. Not to mention the hormones provided to enhance milk production in dairy cows, so that a new marketing ploy runs like this, "No BST is fed to our dairy herd".
BST or BGH is bovine somatotropin, a bovine growth hormone.
Besides the deliberate feed additions, the human sex hormone released to water treatment plants via flushed female urine is not eliminated there. More inadvertantly, there is a class of industrial chemicals [bisphenol A], that mimic sex hormones, some of which find use in thermal printing paper, such as you might find at a restaurant: best not to use a rolled up bill to pick your teeth!
Here's a government broadsheet with a few details.
