Presently, sustainable management of the marine environment is one of the global problems. Namely, the pollution of the marine environment in recent decades has been increasingly pointing to the need for legislation, the introduction of control and prevention because the world is facing pollution of the world's seas and oceans and potential negative effects of such pollution on marine life, particular industries and human health. One of the leading problems concerns the pollution of the sea and the ocean by plastic. This applies not only to large plastic, but also to the microplastics as an extremely abundant pollutant of marine and ocean environment with negative and lasting effects. Therefore, it is important to address these issues nationally and globally in a systematic manner, thus reducing the negative effects of microplastics on the marine environment, as well as affecting the sustainability of the sea and oceans.
