Again source. Nature kept a balance before the existence of men, hunting from what I can see has only brought extinction to several species. Humans aren't a special cookie, you aren't keeping the natural balance of the world, all other animals out there don't use guns, they use their natural abilities to hunt which allows one to overcome the other, this is what represents the natural balance, not guns and hunters. Of course if you can provide/direct me to information that states otherwise I can change my position.
Alcohol isn't a hobby, the issue with alcohol it's well documented, however I need to understand your reasoning of why you think because the bad impact of alcohol we should overlook? the negative impact from the hunting hobby. What's the point you're trying to make. You're just saying alcohol is worst and nothing is done about which is wrong plenty is done against alcohol and in some places it's consumption is completely prohibited.
