I've already explained - twice - why I've asked the question.Ok after all this time i can't help butwhen you are asking for an answer about it. You just make my day!
I'm pretty certain that you did.Alex_Spider said:Oh god I'm crying from the laughs. Ok i had a change of heart. I never said it is wrong to kill an animal other than self defence reasons.
This is actually much better than anything you've provided previously in terms of a justification, but it still doesn't answer the core question re: morality.Alex_Spider said:No great philosophical reasons needed. It is just unnecessary to kill an animal for no reason. We don't need meat at all to survive and thankfully we live out of the caves and dont need their skin anymore to keep us warm. Let me guess i still haven't backed up my thesis? lol
At least you actually put some effort into this answer.

I love that you followed this with links about plant responses to stimuli, when I was clearly referencing our discussion about morality.Alex_Spider said:Yeah we all know how that turned out![]()
This is a case of interpretations run wild. The fact that plants can respond to external stimuli doesn't translate into awareness or the comprehension of pain. Williams' interpretation of the results don't follow from the key findings of the study. Namely:Alex_Spider said:"OpinionDecember 9, 2008 at 4:54 AM
Recent studies have proven plants have feelings, too.
Researchers from Michigan State University have discovered that plants have a rudimentary nerve structure, which allows them to feel pain. According to the peer-reviewed journal Plant Physiology, plants are capable of identifying danger, signaling that danger to other plants and marshaling defenses against perceived threats. According to botanist Bill Williams of the Helvetica Institute, "plants not only seem to be aware and to feel pain, they can even communicate."
This research has prompted the Swiss government to pass the first-ever Plant Bill of Rights. It concludes that plants have moral and legal protections, and Swiss citizens have to treat them appropriately. The Penn State Vegetarians Club would do well to investigate this data before claiming to be superior to those of us who do not subscribe to the idea that eating meat is morally wrong.

[P]lants are capable of identifying danger, signaling that danger to other plants and marshaling defenses against perceived threats.
None of these responses require any level of self-awareness, nor do they require the ability to feel pain. These constitute automated responses to external stimuli.
If the argument you're trying to make here is that plants can suffer, then you're failing pretty miserably. You're relying on loose interpretation and imprecise language more than any actual scientific evidence.
Bose discovered the use of electrical signalling in plants, also indicated in the video you showed earlier. Again, his interpretations of the experimental results are suspect.Alex_Spider said:"The hidden world of plants.
Can plants really feel?
An Indian scientist, Dr. Jagadishchandra Bose, invented a instrument called the crescograph. The crescograph is a device that measures growth in plants. Bose experimented with temperature, chemicals, gasses and electricity.
In his research in plant stimuli, Bose showed, that plants responded to various stimuli as if they had nervous systems like that of animals. He therefore found a correlation between animal and plant tissues. His experiments showed that plants grow faster in pleasant music and their growth is ******ed in noise or harsh sound. Bose came to the conclusion that plants can “feel pain [and] understand affection.”
Putting this into an evolutionary context, you'd have to wonder why a plant would respond positively to affection. This is a hurdle that Bose (nor any other botanist) has ever been able to pass.
Also, music itself is a physical stimulus: patterned compression waves. No awareness is required for it to have a potential effect on plant physiology.
Backster's "study" was also widely panned among scientific circles for his sloppy methodology, calling into question the results of his experiments.Alex_Spider said:Are plants intelligent?

This was the conclusion of Cleve Backster back in the 1960s. He’s the former CIA interrogation specialist that connected polygraph sensors to plants and discovered that they reacted to harm (i.e. cutting their leaves) and even to harmful thoughts of humans in proximity to them.
Backster decided to see what would happen if he threatened a plant, and formed in his mind the idea of lighting a match to the leaf where the electrodes were attached. What happend next was something that forever changed Baxter’s life and ours. For the plant didn’t wait for him to light the match. It reacted to his thoughts! In fact, Backster found that plants are not only psychic, they also are prophetic, anticipating negative and positive events, including weather.
Also, I don't think the results have been successfully replicated. The Mythbusters gave it a shot, too. It was a fun episode. Not a scientific source, granted, but if you're at all interested:

This can be achieved entirely through hormonal responses. Yet again, none of these responses require any actual perception of pain, nor do they require any self-awareness.Alex_Spider said:Plants have many different ways of defending themselves. Some stradegies are the use of chemicals, physical characteristics, or by encouraging the presence of natural enemies of herbivores. Thistles, roses, and many other plants are covered with sharp spines. The large thorn-like stipules of Acacia collinsii are hollow and afford shelter for ants, which in return protect the plant against herbivores.
Nettles have tiny hairs full of painful chemicals. If an animal tries to eat one, the hairs give the animal’s mouth a “shot” of those chemicals. Foxgloves produce several deadly chemicals, namely cardiac and steroidal glycosides. Ingestion can cause nausea, vomiting, hallucinations, convulsions, or death.
When an antelope or other large animal chews the leaves of an African acacia tree, the tree calls out a warning using gas! First the tree pumps chemicals into its leaves to make them taste bad. Amazingly, it also sends a special gas out through its leaves. As the gas drifts to other acacia trees, it “tells” those trees, “Look out, hungry animals are on the prowl!” Then the other trees start pumping the chemical into their leaves.
I never argued that they were incapable of responding to their environment. Where did I ever say they couldn't? I also never argued that they were "lifeless."Alex_Spider said:There are plenty of similar links but I won't waste my time trying to prove the obvious to you. Of course plants are not intelligent like we are but they are still a life form that feel in some way and interact with the air, the sun and the environment. They are not a lifeless thing. That's what I was trying to explain to you but you got back with that "genius phd" attitude and the baseball remarks.
You seem intent upon misinterpreting nearly everything I say.
For the record: you specifically claimed that plants can FEEL through the use of NERVE receptors. The context of your claim seemed to imply that plants can suffer, i.e., can perceive pain. This is the claim with which I take issue.
