Pet cremation offers a controlled, hygienic farewell but consumes energy and may release emissions. Natural burial, like backyard interment, is eco-friendly, allowing pets to return to the earth, but raises ethical concerns about land use and regulations. Cremation suits urban settings; natural burial aligns with sustainability but requires legal checks. The choice hinges on balancing environmental impact with personal values and local laws.Related websites:  https://www.petmd.com/general-health/pet-burial-options
