The reasons to choose cremation are usually personal, though in some cultures it is the preferred choice. In the United States more and more people are choosing cremation. Currently, about 54% of people choose to be cremated. That percentage is expected to rise considerably over the next several years. Reasons range from cost to environmental concerns to simplicity.
Cremation cots considerably less than a traditional burial, upwards of 50%. Cremation doesn't require embalming, a grave plot or burial. It also doesn't include a casket. Burial urns are much cheaper than caskets.
Cremation allows a family the flexibility they may need in planning and preparing for a memorial service, celebration-of-life, or a scattering ceremony. While the cremation process can occur almost immediately, the decisions required in planning a memorial for a loved one can be made in a relaxed manner and in a way that best suits the deceased. Choosing cremation allows a great deal more flexibility regarding time. Time for people to make arrangements, time to plan something more meaningful, and time for family members and friends to be able to attend.
Some people prefer to donate their body to science to help future generations. In these instances it makes more sense for cremation and a memorial service.
Others choose cremation because they don't want to be a burden to those left behind. They don't want anyone to have to tend their grave and take care of flowers or the site where their body is buried.
Others have a deep and abiding love of the sea or the mountains, or a favorite spot where they grew up, and prefer to have their ashes scattered in that location.
For many, concern for the environment is paramount. They don't want to be responsible for polluting ground water for future generations.
Some people don't like the idea of rotting in a box somewhere.
The point is, there are many reasons to choose cremation. While the reasons are mostly personal in nature, they can also be good for the planet and life on earth. Most religions today have recognized this and allow for cremation. (You can read about the relationships between religion and cremation here)
