Tideline 21st century style. This area of the upper reach of the tide should be decorated with seaweeds and shells, yet today's tidelines consist more and more of micro plastic. By definition microplastics are plastic pieces less than 5mm in length and these small plastic pieces are being either ingested by fish, shellfish and birds (and eventually will cause their death) or being ground to even smaller pieces that eventually release toxins (e.g. Polychlorinated Biphenyls) into the environment. This is why we have to stop producing and using single use plastic and go back to glass bottles, cardboard and other biodegradable packaging.
