I believe you have to be a total vegetarian to do that more practically.

Uhmm it’s too difficult. Well, it is optional, though.

@simonex, in the US, there are so many deer in most places that if they aren’t hunted, the deer get weak and starve to death over the winter. Hunting helps the animals, and those that are killed die a quick death rather than weeks of agony as they slowly starve to death. In years like the winter of 2013, when the winter was far worse than normal, even hunting just barely helps. That year, the estimated winter-kill (animals that starved during the winter), counting all the states except Alaska and Hawaii, was about 40,000 animals that died of starvation.
