Explanation:

We are used to seeing advertisers use models with very thin bodies and athletics in surrealistic fashion. This type of media ends up putting a standard of beauty impossible for the majority of the population. All women want to be thin as models used in lingerie ads, all men want to be muscular and defined as models of perfume commercials. In pursuit of this standard of beauty, people end up undergoing extreme diets and harmful and very dangerous health exercises.

Traders should use this power of influence and use models with healthy and realistic bodies, so ads would provide reduced pressure to undereat or exercise at unsafe levels. People would be happier and healthier.
