道义原则
捕鲸：
Killing whales for human use is morally wrong.
Modern whaling is humane, especially compared to the factory farming of animals like chickens, cow and pigs, .
捕猎：
Traditional hunting methods are often particularly cruel.
Overall, however, the essential point is that it is morally wrong to kill animals for pleasure and no amount of economic benefits can make that right.
动物试验：
We need to make sure that the millions of animals who are used for testing new products are treated with the minimum of suffering. Although some animal testing may be unavoidable at present, treating our fellow creatures as mercifully as possible will demonstrate our humanity.
Those against the use of animal testing claim that it is inhumane to use animals in experiments. I disagree completely. It would be much more inhumane to test new drugs on children or adults.
治疗还是教育：
Obviously, there is a strong human argument for catching any medical condition as early as possible.
