The global load of marine floating plastic litter in surface waters is much smaller than expected based on the loads of mismanaged plastic entering the marine environment. Therefore, it is necessary to identify marine sinks holding the missing plastic, to assess risks and impacts and plan interventions to manage this new facing problem. Recent research has shown that mangrove trees occupy the intertidal fringe and develop a partially emerged root system, pneumatophores as a sieve, forming an effective filter that trap different objects and litters transported by currents, like floating plastic objects. In other words, mangroves act as sinks for marine plastic litter as well as a barrier for anthropogenic debris (entering from land to the sea) before they are dispersed in the marine environment. Furtheremore, some large plastics after released into the environment, might undergo a variety of biotic and abiotic processes through which they become smaller and smaller plastic particles instead of disappearing. These small pieces of plastic particles are called microplastics and are less than 5 mm in size and are therefore not visible to the naked eye.
