$this->bbcode_second_pass_quote('untothislast', 'I')f you don't believe animals have, and express complex emotions, you need to spend more time around them. While they're alive.
I totaly do believe that. My point is, when I play with my dog, she's a mammal. So she shares a lot of the same facial expression, body language, etc that I would use to convey emotion. It is comparatively easy for me to presume what she's feeling or thinking (though I will never know conclusively.)
If I, instead of a dog, had a pet snake....well, biologically me and a snake are alot further apart. I can make some assumptions about what a snake is experiencing or thinking based on body language, but it's gonna be a lot harder. That doesn't infer that the snake doesn't have a complex and relevant experience of the world. For example, I can identify certain types of nerves that in humans convey pain. If I then find those in a dead snake, I can conclude that the snake was probably able to experience something similar to my pain sensation. Do snakes experience joy, sadness, boredom? Beats me. I don't know how you would know if they did.
Now me and a carrot...ohh boy. Way different. I can move in 20 seconds, further than most plants will move in their entire lives. A carrot doesn't have any of the forms of communication that I as a mammal am familiar with: no speach, no body language. Even our structure is radically different from eachother, so if I cut open a carrot, I don't see any nerves or anything that remind me of my nervous system. So the question then is...can I reasonably conclude that the carrot doesn't have any meaningful ability to experience the world, i.e. that it is not sentient. I'm not sure that you can say that at all. There is increasing evidence that plants have a whole host of biochemical responses to stimuli. I don't think that you can say that, for example, just because a plant doesn't withdraw from pain in the way a dog would, that it is incapable of experiencing pain.
$this->bbcode_second_pass_quote('untothislast', 'Y')es, humans are destructive and greedy - that seems to be our role on the planet.
Well certainly that's part of it. The bigger reality though is that Mother Nature just didn't see fit to equip you with Chlorophyll. Instead she gave you a mouth and teeth and declared that the only way for you to survive was to kill and eat other things. I suppose one way to look at it is that plants provide their own energy and are therefore morally superior to animals. Realistically, I think you are what you are. You are a heterotroph. You have to eat other living things in order to live. You can decide to only eat plants, because you hope that maybe plants aren't sentient and don't mind being eaten. I personally don't see how that makes you any better or any worse morally. I think the truth is more along the lines of the first tenant of Budhism: "All life is suffering". The only way to avoid suffering, or to avoid causing suffering, is not to be alive.
