Logically, it follows. Life consumes life, in order to live, and everything has its particular niche and diet. However, positive thoughts in 3D STS is something that is extremely hard to identify, if not genuinely have for its own sake -- you attempt to emulate them for selfish reasons, and through that, those efforts usually become counter-productive, or end up being rather useless.
And yes, food is "food". Look at what individuals anywhere are doing whenever they have some time -- re-posting some engaging content or social media while also giving their usual spin or comment, which eventually works to propagate similar vibes of thought and emotion among a viewership. Just because they don't physically eat it, doesn't mean they don't mentally consume it, or on a digital setting, serve it up on a pewter platter for 4D STS feasting. I think it's pretty funny, as there is a clear work-around to any apprehensiveness on this idea, in the modern English.
Now, the virtue of beauty is also an object, an objective possibility, an inherent preference, and a subjective perception, btw. With all virtues, you need a 3rd party designation to verify and validate your observations. Without which you'd just be doing things on your own, per your own predilections.
As an example, for you to find some vase to be aesthetically pleasing, you must first observe it, and then compare your observations with your significant other - lol. Otherwise the vase is not worth the money! But if maintaining a style of interior decoration to stupefy and astound visitors is not your concern, then pretty much anything that's around the idea of a vase will do - like using one of those mini trashcans to set and display a bunch of random flowers that you've found outside. Of course, if you'd asked the plants regarding their opinions on your sense of beauty, they'd probably think it's quite grotesque, morbid, and rather diabolical that you guys display their cutup parts like some art piece.
So in that sense, maybe beauty will save the world, eventually .... when people actually realize what they're doing to other creatures, if not each other, mindlessly.
