The logotype of Plantagon is designed in relation to our underlying idealistic principles. It was designed a long time before emojis became popular.
The ring symbolizes all time, the left bracket symbolizes everything from the past that has happened until now, the right one symbolizes everything that will happen in the future, and the space in between is where human mankind is at the moment. The symbols in the middle are not connected to the ring, because there is no answer of what this connection should look like. The questions the logotype is aiming to address is what responsibility humans will take for the future, and how this will affect us as human beings. The logotype is named Evolution or the Good Warrior (as it relates to a face closing its eyes due to the sharp effort to do good).
