Downvoted. It's a semi-serious article, not something that suggests you shouldn't eat plants (what else can you eat? meat? cows eat lots of plants when they are being raised).
Only a really disingenuous person would claim it's kinder to eat meat. There's arguments in favor of eating meat (there's some book called "The Mindful Carnivore" which goes a bit deeper than "meat bad veg good"), but ... that's way off topic.
Nobody with half a brain thinks plants scream when you eat them, and that's not what the article is saying.
