Core Viewpoint - The article discusses the evolution of American funeral customs in the 21st century, highlighting a shift towards more personalized and diverse practices that reflect individual beliefs and values regarding death and memorialization [5][28]. Group 1: Historical Context of American Funeral Practices - In the 20th century, American funeral customs were characterized by a standardized approach, heavily influenced by a fear of death and a tendency to conceal it from public life [7][12]. - The Civil War marked a significant turning point in American funeral practices, leading to the professionalization of the funeral industry and the widespread adoption of embalming techniques [11][12]. - By the 1960s, approximately 95% of deceased individuals underwent embalming, establishing a norm for American funerals that included body viewing and preservation [12]. Group 2: Changes in 21st Century Funeral Practices - Since the turn of the century, there has been a notable rise in green burial practices, with many Americans expressing a growing disinterest in embalming due to environmental concerns [14][15]. - The concept of "natural burial" has gained traction, with eco-friendly burial sites using biodegradable materials and avoiding harmful chemicals [15][16]. - The popularity of cremation has surged, with a cremation rate reaching 21% by 1995, and some states reporting rates as high as 50% [17]. Group 3: Emergence of Personalized Memorialization - A variety of creative memorialization options have emerged, including memorial items made from ashes, such as glass art and life gems, which allow families to keep a tangible connection to their loved ones [18][19]. - The trend of creating personalized memorial items reflects a desire for unique and meaningful ways to remember the deceased, with services offering custom pieces that incorporate ashes [19]. - The rise of DIY funerals has also been observed, with families taking a more active role in the funeral process, reflecting a return to pre-industrial practices [21].
