The impact of the CSMA’s objective to remove and extract the plastic from beneath the ocean surface is a highly complicated and demanding task, requiring substantial work labour of highly experienced divers. This method is the most effective. It is not mechanical and does not inflict additional damage to marine life and fauna. CSMA Plastic Extraction refers to cleaning by extraction of plastic marine debris of all types visible to the human eye and up to large pieces measured in tonnes. The elimination and extraction of large pieces of plastic reduce the creation of additional microplastics.
