“The [bonnethead shark] successfully digested the seagrass with enzymes that broke down components of the plants, such as starch and cellulose. Lacking the kind of teeth best suited for mastication, the fish may rely on strong stomach acids to weaken the plants’ cells so the enzymes can have their digestive effects. In all, more than half of the organic material locked up in the seagrass was digested by the sharks, putting them on a par with young green sea turtles.” https://www.theguardian.com/environment/2018/sep/05/bonnethead-omnivorous-shark-species-identified

“Marine plastic litter can already be controlled through the United Nations Convention on the Law of the Sea (UNCLOS); the London Convention; the MARPOL Convention; the Basel Convention; Customary Law, and many other regional agreements.
Article 194 of UNCLOS, for instance, requires states to ‘prevent, reduce and control pollution of the marine environment from any source.
Measures shall include, inter alia, those designed to minimize to the fullest possible extent… the release of toxic, harmful or noxious substances, especially those which are persistent, from land-based sources… [and] shall include those necessary to protect and preserve rare or fragile ecosystems as well as the habitat of depleted, threatened or endangered species and other forms of marine life.'” http://www.bbc.co.uk/news/science-environment-43115486
“A spokesman for [SEPA] said: ‘Our officers are comfortable that there is no environmental risk to the River Cree as a result of the bottles being released and, following inquiries, understand almost all of the bottles were contained and removed from the river fairly quickly by local residents.’ …
‘It was never my intent to harm the environment. It was more accident, naivety as well as stupidity in the execution. … It was just my intention to send a wee love bottle with a message to someone I had not yet met.'” http://www.bbc.co.uk/news/uk-scotland-south-scotland-40738484
