The anthroposphere (sometimes also referred as the technosphere) is that part of the environment that is made or modified by humans for use in human activities and human habitats. It is one of the Earth's spheres. The term was first used by nineteenth-century Austrian geologist Eduard Suess. The contemporary concept of the technosphere was first proposed as a concept by American geologist and engineer Peter Haff, of Duke University. It has been estimated that as of 2016 the total weight of the anthroposphere - that is, human generated structures and systems - was 30 trillion tons. The anthroposphere can be viewed as a human-generated equivalent to the biosphere, which is why some authorities consider it synonymous with the noosphere. While the biosphere is the total biomass of the Earth and its interaction with its systems, the anthroposphere is the total mass of human-generated systems and materials, including the human population, and its interaction with the Earth's systems. However, while the biosphere is able to efficiently produce and recycle materials through processes like photosynthesis and decomposition, the anthroposphere is highly inefficient at sustaining itself. As human technology becomes more evolved, such as that required to launch objects into orbit or to
