lets take it with another approach, we eat meat that r commercially produced, that means involving breading n making it ready for meat its all humans's activity, so if we stop eating then surely their number is going to decline anyway, animals do have feelings may not be as good as us in sharing it but I agree they do have it..but still the question is we r making them for our own use n their destiny(like the chickens used comercially) is to serve us for food..so lets not put emotions n our habits on the same place. Studies has proved that we have intestinal system as that of a chimpange(corr.sp)not as that of a dog but the same studies suggests that taking limited amount of meat does no harm to us..so cheer up guys....I completely oppose the way they treated chickens in that video ,shud admit that killings in butcher shop in our country is much better than this , atleast we cut off their head rightaway which means less suffering.
