A incapacidade de reconhecer a importância das plantas na biosfera e no cotidiano, bem como a dificuldade em perceber os aspectos estéticos e biológicos exclusivos das plantas é chamado de "Cegueira Botânica", termo desenvolvido por Wandersee e Schussler (2001). Essa falta de percepção visual sobre as plantas muitas vezes ocorre devido ao processo...
