Total Human Population Mass
8 billion people weigh about 518 million tonnes combined/Collective & Conceptual
With approximately 8 billion people on Earth and an average body mass of roughly 62 kg (accounting for children and global variation), humanity's combined mass is about 518 million tonnes. Our total blood volume is approximately 40 billion liters, enough to fill 16,000 Olympic swimming pools. Despite these impressive numbers, humans make up only about 0.01% of all living biomass on Earth. Plants outweigh us by a factor of about 7,500.
