Plants didn't evolve with the means to see danger coming or legs, fins or wings with which to escape danger and destruction. Most of them also can regenerate if they are harvested and the roots left in the ground.
Animals on the other hand evolved with real escape mechanisms. Noses to smell enemies, eyes that can see better than us and ears that can hear a mouse rustling in the straw. And they all have either legs, fins or wings so that they can escape.
Plants have the job of taking the energy from the sun and the CO2 that is in the air, convert it to tissue and feed those animals. That's their job. And even the Bible points us towards eating only plants in those first moments of the Biblical creation story. Gen.1:29,30.
Our entire physiology, from the design of our teeth and jaws and the digestive system from stem to stern is suitable for eating plants. Even the acids in our stomachs are not strong enough to kill the bacteria that is inherent in meat, which is why true carnivores and omnivores (like bears and pigs) can eat road kill that's been laying there in the sun for a couple of days, and not get sick. Whereas we would die from the buildup of toxins and bacteria.
Animals are beings with sensibilities no different than ours. They love, they fear, they feel pain, they bleed, they suffer and they die....just like we do. They are not here for us, they are here for them.
I'll just address each of your points in order:
1) Plants may not have all the same senses as animals, but that doesn't mean they don't sense. Scientists have proven they can at least smell.
Plants can smell, now researchers know how: First steps to understanding biochemistry of how plants detect odors
2) They may not be able to escape danger, but that doesn't mean they don't try to defend themselves against being eaten with bark, shells, spines, thorns, and even toxins.
3) Re: most can regenerate if roots are left.. So, are you suggesting we should not eat root vegetables (carrots, potatoes, onions, garlic, beets, etc) because that would be murder, but berries and seeds are ok? Are you saying it would be ok to eat parts of animals that regenerate (e.g. lizard tails, spider legs, starfish arms)? If berries and seeds are ok, does than mean animal eggs are ok, since these are both just a means of reproduction?
4) Plants do convert CO2 to O2 and create growth with the Carbon part.. Doesn't have anything to do with "for the consumption of animals". And does that mean an antelope eats the grass to grow for the lion to consume it too? Are you not just describing the food chain here?
5) The bible is a completely irrelevant argument. It was written by man. Has about as much relevance on what we should eat as a book written by a vegan. If you believe in supernatural beings, that's an opinion, and there are plenty of varying opinions on that subject alone (e.g. the Qu'ran does allow for eating meat, but that's just another book written by man, and should be take with equal weight).
6) Our physiology is designed to be an omnivore. Our teeth for example, we have molars and incisors (like cows or rabbits) for cutting and grinding plant material, yes. We also have canines (like dogs and cats) designed for tearing apart meat.
7) I know people who eat raw meat (including ground beef), and have done so for their entire lives (60+ years) without getting sick. How our bodies handle bacteria is more dependent on our gut flora. Our sterile lifestyle and use of preservatives in food, chlorine in water, and antibiotics all contribute to killing our gut flora, making us less able to handle things that our wild omnivore brethren can still handle. But people who have re-adapted themselves to raw meat diets still exist today and do not get sick and die.
8) Animals may be more similar to us than plants. But that doesn't say anything about what plants can/can't sense. Until recently, we didn't know plants could smell, or how that worked. Many plants effectively bleed if you cut them, though it may not look like our blood. And they die if we rip them up, and we really don't know if they suffer or not. We just don't care cause they don't have cute little eyes like us.
9) "They are not here for us..." is an opinion.
The underlying fact remains the same.. We kill virtually everything we eat.
If only killing plants to eat makes you feel better about yourself (for whatever reasons), then go for it. I'm not going to tell you what you should/shouldn't eat. But I do expect the same courtesy in return.
