Respecting plants involves seeing them as valuable beings on their own terms, and not just as sources of raw materials for human use. It means that plants deserve moral consideration in all of the ways in which people interact with them.

Actually, this is not a new idea at all! In many cultures, past and present, plants are treated with honor and respect. 

These terms have different nuances, but one commonality is that plants are treated more respectfully in each of these approaches.

There are many books, articles, videos, and audio recordings that provide valuable background on plant ethics and plant intelligence.

A good starting point is a 50-minute radio show "Plants as Persons" from To the Best of Our Knowledge that aired December 19, 2020 and includes interviews with Robin Wall Kimmerer, Matthew Hall, Monica Gagliano, and Brooke Hecht.
