But the fact is we do kill those plants. Those tomatoes are filled with seed intended, by nature, to propagate the species, but the chance of that dies when you eat them, and then the entire plant dies. There are no birds eating their fruit and spreading their seed. It that were the case we'd see tomatoes growing wild all over the US, but we don't.
Carrots, lettuce, broccoli, radishes, etc, etc, are all harvested (murdered if you will) before they even get a chance to go to seed. Your reminder doesn't account for that.
So, yes, in fact, billions of plants are murdered each year because we humans eat them.
I'm more curious about why this so difficult for some people to accept. It's obviously driven by empathy and compassion, and I admire that, but it ignores the facts that plainly exist all around us all the time.
The latest figure I could find easily says "In 2008, 9.08 billion chickens were slaughtered in the United States".
And tomatoes? "According to the United Nations Food and Agricultural Organization statistics, around 340 billion pounds (170 million tons) of fresh and processing tomatoes were produced globally in 2014. The harvested area covered 12.4 million acres (5 million hectares) of farm land."
That's a lot of food for a lot of people. All of it brought to life that's taken for one purpose, to sustain us.
This does not make us murderous beasts, and no one, not even those who've claimed to be "Breatharians", has proved they could exist without taking life. There's just no getting around that necessity.
As far as I can make out, this notion that one is existing without taking life is almost exclusively found in cities, generally far from where food is grown and harvested. I'm pretty much convinced it is a willful denial of the truth created by and to convince oneself they are superior to the crude masses who haven't achieved their advanced level of conscientious. And it's a growing trend.
The fact is, it's an example of denial. We all take life to sustain our own. The best we can do is provide the means for it to flourish and take it in as painless a way as possible, rather it's a chicken or a radish.
