killing for sport by Joseph Wood Krutch.

First I think we need to distance ourselves from the concept of killing for sport and Hemingway's masterpiece. Santiago was not killing for sport. The hunt and his Marlin would have resulted in Santiago not starving to death. There are themes within the story that a "sort hunter" might recognize but certainly not in the same way that Hemingway weaves his character and his tale. That said,I'm going to include an article that I find compelling. I'm sure there are plenty of opposing view points but this is close to how I feel. The source-link is below.

"Many animals suffer prolonged, painful deaths when they are injured but not killed by hunters. A member of the Maine Bowhunters Alliance estimates that 50 percent of animals who are shot with crossbows are wounded but not killed.(7) A study of 80 radio-collared white-tailed deer found that of the 22 deer who had been shot with “traditional archery equipment,” 11 were wounded but not recovered by hunters.(8) Twenty percent of foxes who have been wounded by hunters are shot again; 10 percent manage to escape, but “starvation is a likely fate” for them, according to one veterinarian.(9) A South Dakota Department of Game, Fish, and Parks biologist estimates that more than 3 million wounded ducks go “unretrieved” every year.(10) A British study of deer hunting found that 11 percent of deer who’d been killed by hunters died only after being shot two or more times and that some wounded deer suffered for more than 15 minutes before dying.(11)

"Hunting disrupts migration and hibernation patterns and destroys families. For animals like wolves, who mate for life and live in close-knit family units, hunting can devastate entire communities. The stress that hunted animals suffer—caused by fear and the inescapable loud noises and other commotion that hunters create—also severely compromises their normal eating habits, making it hard for them to store the fat and energy that they need in order to survive the winter."

15 minutes before dying. That sounds so depressing...
