Also known as a water cremation, this process is considered to have the lowest environmental impact compared with burial and flame cremation. For those of you who have lived your lives with a very acute environmental awareness and concern for our planet, water cremation certainly allows you to express that concern in a very positive manner, even at the end of your life. Choosing water cremation over flame cremation and burial comes down to each individual and is in some cases driven by tradition or religious beliefs. For others it is simply that choosing water cremation seem a gentler option and the right choice for them. This process is a very new alternative to burials and cremations, so it is not yet legal everywhere.
