America limits deer hunting to the animals 'breeding season to give the herds a breathing space and the chance to reproduce, and hunting equipment is continuously "progressing" from the rifle to the bow and arrow, and even to the point where one may only load one bullet in the rifle or put one arrow to the bow. If the first shot misses, then one should give the animal its life.
美國也限制人們只能在鹿的繁殖季節狩獵，如此鹿只族群才有繁衍、喘息的機會；野外打獵工具也由槍不斷「進步」為弓箭，甚至到槍或箭上只裝一顆子彈、一根箭鏃，一次不中，就應放獵物重生。
