Why would you not kill the old ones? Just like fish you keep the large ones and throw back the small ones so that they can become large. Your logic makes sense not does.
my logic does not make sense......really..... killing something that has been around that long...just to kill it makes sense to you?
killing an animal just to kill it is acceptable to you?
well I am glad my logic makes perfect sense to me....I eat what I kill....and would only kill an animal as a last resort....and then only if it was an immediate threat to human life.(and that depends on the human)
maybe you should think about what you said there a bit....actually spend some time thinking about what you said...you may find what you said is absurdly ignorant.
and comparing a fish that's been around for a couple years...to an alligator that's been around probably close to a century.....

this is one of the biggest problems with people that I cant stand..and makes me ashamed to call myself human....they have no respect for life.....any life...except there own of course.....
you one of the type that think because you are human you have the right to kill whatever is "beneath" you?
in my eyes..... because we are humans...it is our duty to take care of this world and the animals that are in it....
one last thing...just because we can do something.......does not always mean we should.
