Sexualising your diet

Can someone please explain something to me, why do we feel the need nowadays to use our sexuality to sell  just about everything? I mean I find it baffling as to why advertisers feel that scantily clad men and women will make a product more desirable to consumers. Yes, I know that "sex sells" but it has gotten totally out of hand. I mean look at these pictures from PETA to try and encourage folk to be veggie or vegan...

Looking at the two pictures does it honestly make you want to stop eating meat? Do the two ads make you understand the virtues of being veggie, do they talk about cruelty to animals, do they actually sell the idea to you? Or are they two cheap excuses to photo a couple of scantily-clad blondes?

Perhaps I'm missing the point somewhere along the line but I truly do not get why it is seen as normal for us to effectively sell our bodies in photos or in television adverts all in order to flog someone something. Are things really worth sacrificing our dignity? Call me old fashioned but I thought that we were worth more than that. Our human flesh, these wonderful bodies are fashioned in the image and likeness of God, redeemed by the passion, death and resurrection of Christ and no consumer product can ever be valued anywhere near as highly as we are. Yet we readily put them on show, sell them to the highest bidder in order to make a buck. In the eyes of the media we are no longer seen as we should be, in the way the God sees us and always intended us to be, but instead as "models", objects to be used for a specific purpose and later discarded. It defiles our nature, degrades us and in turn reduces our view of our fellow men and women.

Why can't we go back to advertisements that actually tell you something without someone stripping off or faking an orgasm or whatever? Wouldn't they, for one thing, be more interesting? Wouldn't they be more effective? Or m I just a prude?
