yeah, us humans kinda screw up pretty much everything around us, we all contribute, I guess some people just have to convice themselves that what they are doing isn't bad....but the truth is...it all is kinda. even everything I do....some people are just fine with doing some "damage" and hopefully they respect the things they are affecting and do it with at least the least damage they feel right. haha, I wish I knew of some secret spot in chicago where I can scoop up some plecos! haha
