有点长,下面的是这段文章的一部分,
Another problem firms face is that those who modify their products due to increased consumer concern must contend with the fact that consumers' perceptions are sometimes not correct.Take for example the McDonald's case where it has replaced its clam shells with plastic coated paper.There is ongoing scientific debate which is more environmentally friendly.Some scientific evidence suggests that when taking a cradle-to-grave approach,polystyrene is less environmentally harmful.If this is the case McDonald's bowed to consumer pressure,yet has chosen the more environmentally harmful option.
