The term 'Future Ferns' refers to the spores of ferns, which are small, single-celled reproductive structures that are released by ferns and other plants. Spores are the primary means of reproduction for ferns, and they are capable of surviving in a variety of environments. When the spores land in a suitable environment, they will germinate and grow into new ferns. The term 'Future Ferns' is used to refer to the potential for these spores to develop into new ferns, thus ensuring the future of the species.
