What's Earth's dominant species by mass?
Scientists estimate that humans, with a combined mass of about 350 million tonnes, are the heaviest species on Earth, surpassing the mass of all other animals, plants, and microorganisms combined. The calculation includes the average adult weight and global population, showing that human activity has made our species the planet’s most massive biological entity. This finding underscores the ecological footprint of humans and highlights the importance of practices to mitigate ecosystems.
