If you think the biosphere is pretty cool check this out! At the University of Arizona they have created a new biosphere! This complex spans over three acres and has cost over 200 million dollars to create. The goal behind Biosphere 2 is to bridge the gap between our biosphere and science by creating a living laboratory of sorts. The idea is that within this strictly manipulated environment scientists will have the opportunity to better observe how the environment works. The reason this is so important is because scientific equipment that cannot be easily transported can be implemented to take readings and perform experiments. There is a bit of controversy surrounding the success of this establishment but regardless, it is a vital experiment in the eventual goal of making settlements in inhospitable climates including other planets. Good information can be found in the “science” section of this website where the organization explains its mission and purpose. Definitely worth checking out!
