What do we really know about animal and plant communication? They might very well be talking to each other. Don't be too quick to assume that as a human you would even know how other consciousnesses, let alone ways of communication, could work.
People who work closely with animals seem to lose their 'human smart, monke stupid' attitude relatively quickly, and those who study non-human consciousness deeply seem to make one groundbreaking discovery after the other these days.
We have to stop gatekeeping knowledge and start listening.
