You are so, so wrong about the strawberry or vanilla ice cream decision being free of ethical dilemmas, and I'd say it's about time you took your blinkers off.
Have you not heard about the child labour used in the world's main vanilla growing country, Madagascar. Without the vanilla trade though there would be abject misery for the Malagasy people. I've lingered by the freezer in Woolies on many an occasion trying to decide whether to buy or not to buy, but apparently you have not Peregrinus.http://humantrafficking.change.org/blog ... sweet_side
On the other hand if you go for a strawberry ice, and turn your back on the suffering Malagasys, then there's a good chance you'll be supporting the good old USA or another relatively affluent economy.http://www.top5ofanything.com/index.php?l=380
You may be a fan of the cheaper synthetic vanilla flavoured confections. That's an unethical decison too if it's for your loved ones as it's a known carcinogen, and you'll be enriching unscrupulous perveyors of toxic food stuffs.http://en.wikipedia.org/wiki/Coumarin
Food for thought Peregrinus?
