I am not aware of any plants that show signs of consciousness or feelings. This would even by disadvantageous to many plants because they "want" parts of them to be eaten to disperse seeds, pollen, etc.

Even if you accept that plants might be conscious and their suffering has to be reduced, you would still harm way fewer plants by eating them directly instead of eating other animals that consume them.

Your “what about plants” argument is such a worn-out trope that you must have seen it before and read a valid explanation of why it makes no sense.

Peter Singer has been writing on the topic for decades, including others. What-about-plants needs to fade away.
