Our biosphere is the regions of the surface, atmosphere, and hydrosphere of the earth occupied by living organisms. The reason biosphere’s important is because it’s all life. Without biosphere we couldn't live here; nothing would in matter of fact. The planet would be a lifeless planet. The way scientists study the biosphere is by using remote sensing to observe a section of the earth. Combine the data from many orbits to recreate the whole earth at once. The reason scientists study the biosphere is to know how earth works, because if we don't know how earth works we could be degrading our planet
