Bugs, rats, possums, etc. have pretty much no value to me whatsoever. As far as I'm concerned, all cockroaches should die. Horrible deaths as far away from me as possible.

That's an interesting answer- I love all animals and try to be kind to even bugs. But I grew up with fire ants in texas (the kind that kill babies and stuff >_>) so whenever I come across an ant, I kill it. Quickly, without making it suffer.

I think an animal's value depends entirely upon the value derived by humans. Dogs and cats, and other domestic pets, have a higher value because of the emotional or security they provide. Farm animals are valuable because of the food factor. Animals such as these will always hold more cultural significance to humankind than say a ubiquitous squirrel, or even an endangered species that has little symbolism or direct worth for humankind. That isn't to say humans would be callous towards a species' plight, but if it came down to the wire, they will always choose a more culturally significant animal's life over one they have no cultural stake in.

All of the above. Intelligence is important, but so is rarity. Certain animal like goldfish, which are surprisingly intelligent, are not treated right. Just because an animal is cute does not (or should not) give it higher standing than other more intelligent, "ugly" animals.

certain animals seem useless to humans so i am not sure if we should kill them cuz i believe that animals are just as human as we are

Oh and I would like to add, it's pretty stupid to judge on intelligence/usefulness alone because by that logic all the idiots downtown should be used as garden fodder. _{Believe me, I've seen ants smarter then those idiots. :U}

All life has equal value but sometimes, depending a situation, a life's value may be extended over another. For example, I do not value the life of ticks because they only cause harm to so many animals! Dogs, Cats, Birds, Deer, etc, can all get sick due to these parasites and die. Therefore I do not value their life even though their life is no different then another animal but since they cause only harm and difficulty for everyone, no one will suffer if they are gone/dealt with.

50% of people voting here have never killed a cockroach. Riiiiight...
Or! 50% of people voting here is eating panda-steak for dinner.
Anyway, the answer is obvious - cute & cuddly critters have more rights.

I think they're all worth the same, but realistically it's only the pretty or uncommon ones people are concerned with, in my opinion, and the inconvenient ones that get screwed (or not mass murdered, so... idk which option is better). I mean I dont see people going NOOO DONT KILL THE ANTS AND COCKROACHES. THOSE RATS AND LICE HAVE FAMILIES TOO.
