First of all, scattering ashes will pollute the marine ecological environment and may cause harm to marine life.
In addition, ashes contain some chemicals, such as calcium and phosphorus, which may affect the marine ecological balance if they spill into the ocean in large quantities.
Secondly, from the perspective of cultural respect, scattering ashes is an act of disrespect for the deceased. In the traditional culture of China, ashes are the relics of the deceased and should be properly placed and respected. Throwing ashes is considered to be disrespectful and does not conform to social morality and cultural values.
Therefore, in order to protect the environment and respect the dead, it is not allowed to throw ashes. If you need to dispose of the ashes, you should choose a legal way, such as putting them in a cemetery or an urn.
There are specially designated places in the sea burial area. Although sea burial scatters ashes into the sea, it can't be done in any sea area. It must be a special area designated by the maritime department. The ocean currents and tidal currents here are specially calculated. When the ashes are scattered into the sea, they will not float to the offshore fishing and culture areas or the shore, but flow into the deep sea, reducing offshore pollution and preventing the ashes from entering the fishermen's fishing and culture areas.
