This all looks pretty innocent if totally incongruous: cartoon polar bear on an ice floe with a scarf, chillin on a chaise lounge. All representing that the cold food stays cold, even when it's hot outside. Of course, there's nothing "natural" about that. This is a man-made thing this thermal food carrier.
Just as there's nothing natural about global warming which doesn't exactly leave this polar bear so happy on that ice floe.
