What type of garbage can be thrown overboard on island waters?

In island waters, it is generally prohibited to throw any type of garbage overboard, including plastics, food waste, and hazardous materials, due to environmental regulations and marine protection laws. Some jurisdictions allow for the disposal of certain biodegradable materials, like food scraps, but this is often restricted and should be done in compliance with local regulations. It's essential to follow best practices for waste management and utilize designated disposal facilities whenever possible. Always check local guidelines to ensure compliance.
