Question

What is the difference between biosphere and technosphere?​

Answer 1

Explanation:

The biosphere is extremely good at recycling the material it is made of, and this facility has enabled it to persist on Earth for billions of years. The technosphere, by contrast, is poor at recycling. ... The technosphere is an offshoot of the biosphere and, like it, is a complex system with its own dynamics.

Answer 2

Answer:

The biosphere is extremely good at recycling the material it is made of, and this facility has enabled it to persist on Earth for billions of years. The technosphere, by contrast, is poor at recycling. The technosphere is an offshoot of the biosphere and, like it, is a complex system with its own dynamics.

Explanation:

The technosphere, though, differs from the biosphere in one crucial respect. The biosphere is extremely good at recycling the material it is made of, and this facility has enabled it to persist on Earth for billions of years. The technosphere, by contrast, is poor at recycling. Some of the waste is all too obvious, like the plastics accumulating in the world’s oceans and on its shorelines. Other kinds, being colourless and odourless, are invisible to us, like the carbon dioxide from the burning of fossil fuels. The mass of industrially-emitted carbon dioxide in the atmosphere is now enormous – nearly one trillion tons, which is the equivalent of about 150,000 Egyptian Pyramids. This rapid growth in waste products, if unchecked, is a threat to the continued existence of the technosphere – and the humans that depend on it.

The technosphere is an offshoot of the biosphere and, like it, is a complex system with its own dynamics. The capacity of our species to form sophisticated social structures and to develop and work with tools were important factors in its emergence. However, Haff emphasizes that humans are not so much creators and directors of the technosphere, as components within it, and therefore constrained to act to keep it in existence – not least because the technosphere keeps most of the current human population alive, through the supplies of food, shelter and other resources that it provides. Its development has allowed the human population to grow from the few tens of millions that could be kept alive by the hunter-gatherer mode of life in which our species evolved, to the 7.3 billion that inhabit the planet today. Just one technological innovation – artificial fertilizers made using the Haber-Bosch process(link is external) – keeps about half the human population alive.

The technosphere today is not evolving because it is being guided by some controlling human force, but because of the invention and emergence of useful technological novelties. There is now a kind of co-evolution of human and technological systems.
