<s>[INST] The next text is a question of a member of the European parliament:"A research study by Portugal’s Interdisciplinary Centre for Marine and Environmental Research (CIIMAR) has revealed that there are more plastic particles in the Douro River than fish larvae.  Microplastics pollution in estuary ecosystems represents a potential danger for numerous species inhabiting them, either through the ingestion of plastic particles or the particles’ driving them out of their homes or blocking out light. There may well also be effects on trophically similar species.  This concentration of microplastics poses problems not only for the fish larvae, but also for the community as a whole and people in the adjacent coastal areas, whose livelihoods depend on the estuary.  — How far advanced are efforts at EU level to achieve the objective of reducing microplastics pollution?  — Is the Commission aware of any ongoing clean-up projects and how effective are they?  — What EU programmes and measures can help prevent this form of pollution and improve environment in the areas affected?"
