I suppose I was basing my definition of genocide on themes I picked up in various sci-fi novels, such as Xenocide, one of the sequels to Ender's Game... and a story I was reading recently where there was a big debate in a futuristic society whether to attempt to exterminate a hive mind type alien civilization. The word genocide was used in that context even though this alien civilization was more like a bee/ant colony, with no real intelligence in the drones, and more like a collection of robot-like drones.
I wouldn't be surprised if at some point in the future we look back to today and elevate the extinction events we've caused in terms of legal implication.. At this point I fully agree that genocide as we know it should not apply to ducks or tomatoes.
There's an old filksong I learned back in the '80s called "Beware of the Sentient Chili". The lyrics:
Beware of the Sentient Chili
by Chris Weber
Beware of the sentient Chili
that burbbles away on your stove
the peppers are silently plotting
with legumes, tomatos and cloves.
At night when you're comfortably sleeping
and lie unaware in your bed
the vegetables plan insurection
the lettice are seeking new heads.
It may start with slight indigestion
from underdone turnip cake crumbs.
Frustration in several world leaders
whose rice seems to stick to their gums.
In kitchens across every nation
the tinniest things will go wrong.
The plot of the sentient chili
strikes Moscow and Rome and Hong Kong.
The casserol, spinich and cheesecake
lend quite support to the scheme.
The nerves of a planet are streached then
while tempers start slowly to steam.
Still none see the grand machinations
now tilting world balance awry-
The stage set for final disaster.
The chili sits back with a sigh.
The one day the conflict is started
by generals whose lunches were odd.
The mushrooms rejoice as their brothers
stalk city to city like god.
When dust and all clamor are settled
there's not a soul left from the frey.
The sentient chili just chuckles
and happily simmers away.
Here's the YT version (I've heard much better renditions; this one is too slow and the flute is too loud, but at least you can get an idea of the melody):
Moral of the story: Don't be so sure you can trust your food. You never know what it's thinking.
