@bythewell - The ethics of hunting and fishing are actually pretty interesting in some cases. It's not always black and white, but at the same time, often it seems to have some of the best logical decisions made on behalf of the animals.
For example, there are often debates over whether or not certain kinds of game in Africa should be hunted, given that some populations are endangered and others are overpopulated. Does hunting them give rise to more demand to hunt them or does it act as a means of deterring more hunters?
Elephants, for example, are still pretty rare and the population needs to be safeguarded. But there are places where there are so many elephants now that they are putting a lot of pressure on the ecosystem. Moving them is only a short term solution. So should people be given permits and allowed to hunt a few of them? Most people will instinctively say no, but at the same time will not feel bad about people hunting deer.
