Water burials, also known as aquatic burials, involve placing a deceased person's body in a body of water, such as an ocean, lake, or river. This practice is often chosen for its environmental benefits and spiritual significance. The body may be weighted down to ensure it sinks, or it may be placed in a biodegradable container that allows it to decompose naturally. This method is part of various cultural traditions and is sometimes associated with maritime practices. Vikings famously used water burials for their leaders, while some modern eco-friendly options promote water burials as a sustainable alternative to traditional burial methods.
