A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
Very obvious bait post.
Plants are not sentient. Animals are.
All living organisms show basic reaction to external stimuli. Plants follow that. That does not indicate sentience.
Animals have significantly more intelligence than that. They form bonds, form relationships, mourn, and so on.
No living being except probably photosynthesis driven plankton can live entirely without consuming anything alive.
Recent studies actually show the opposite of "no sentience". Plants communicate with each other, even across different species and kingdoms. That means certain animals for example can understand signals from plants better than they understand us.
And that's just communication. The world of life on earth is so much more than the naive human way of thinking. In fact, it's likely we've already encountered multiple different life forms from space already, and we just have no way to know yet.
So please. Jump off the high horse, take off your hat, and acknowledge that the food on your plate has had a very diverse, colorful life. You can still choose not to eat animals. Just like I choose not to eat dogs and cats, some people see them no different to cows, pigs, and plants.
It's all just nutrients. So respect it.
Edit: Here's an example of how much we understand what dogs see https://www.youtube.com/watch?v=Gf4k0VgCQjg
The devastation caused by vegan diets is still being figured out but there's no question that it's absolutely horrific for the ecosystem as insects are destroyed en masse to serve the needs of the industry.
No one wants to talk about what that does to the web of life depending on it though. It's buried just like we see with the health impacts of the plant based meats.
Eat food locally grown and limit your meat consumption. Things aren't as complicated as the media and food industry try to make it seem.
