Eating chicken vs eating dolphin

I am writing in response to the article 'Food for thought' (Young Post, March 22). It mentions the dolphin-killing practice in Taiji, Japan. The writer raised questions about eating dolphin meat but did not explain why eating it is wrong.

It has been a tradition for fishermen in Taiji to hunt dolphins and sell their meat to Japanese consumers. They don't really kill that many each year. And if they do not kill dolphins for sale, their economy will suffer.

I have two questions:

First, what is the difference between eating chicken meat and eating dolphin meat?

Second, when traditional cultural practices such as dolphin hunting clash with social values like environmental protection, how should that be tackled?
