Second, the biomass of terrestrial plants overwhelmingly dominates on a global scale – and most of that biomass is in the form of wood. Humans have culled, and in some cases eradicated, wild mammals for food or pleasure in virtually all continents. “First, humans are extremely efficient in exploiting natural resources. “There are two major takeaways from this paper,” he said. Paul Falkowski, at Rutgers University in the US and not part of the research team, said: “The study is, to my knowledge, the first comprehensive analysis of the biomass distribution of all organisms – including viruses – on Earth.” The researchers acknowledge that substantial uncertainties remain in particular estimates, especially for bacteria deep underground, but say the work presents a useful overview. They used carbon as the key measure and found all life contains 550bn tonnes of the element. They started by assessing the biomass of a class of organisms and then they determined which environments such life could live in across the world to create a global total. The researchers calculated the biomass estimates using data from hundreds of studies, which often used modern techniques, such as satellite remote sensing that can scan great areas, and gene sequencing that can unravel the myriad organisms in the microscopic world.
”I have not become vegetarian, but I do take the environmental impact into my decision making, so it helps me think, do I want to choose beef or poultry or use tofu instead?” “I would hope people would take this as part of their world view of how they consume,” he said. “I would hope this gives people a perspective on the very dominant role that humanity now plays on Earth,” he said, adding that he now chooses to eat less meat due to the huge environmental impact of livestock.īut our impact on the natural world remains immense, said Milo, particularly in what we choose to eat: “Our dietary choices have a vast effect on the habitats of animals, plants and other organisms.” “I was shocked to find there wasn’t already a comprehensive, holistic estimate of all the different components of biomass,” said Prof Ron Milo, at the Weizmann Institute of Science in Israel, who led the work, published in the Proceedings of the National Academy of Sciences.
The vast majority of life is land-based and a large chunk – an eighth – is bacteria buried deep below the surface. Second Extinction, by Generation Zero creators Systemic Reaction, is a simple concept that I might’ve doodled on my homework in junior high school, but it relies on the speed and polish of its.

All other creatures, from insects to fungi, to fish and animals, make up just 5% of the world’s biomass.Īnother surprise is that the teeming life revealed in the oceans by the recent BBC television series Blue Planet II turns out to represent just 1% of all biomass. Bacteria are indeed a major life form – 13% of everything – but plants overshadow everything, representing 82% of all living matter.
