Research into global inter-relatedness is a relatively new multi-disciplinary attempt to understand the complex relationships between the environmental and sociological factors that affect life on the Earth. The biosphere model in environmental science combines all natural and man-made systems within a single system where the effects and relationships between factors can be examined more closely. This examination includes the levels of natural organisation in biosphere, chemical composition of the biota, genes, chromosomes and reproduction, evolution, the classification of organisms, energy, nutrients and life processes, ecosystem function, photosynthesis and primary production, heterotrophic organisms and secondary production, the transfer of energy and matter within ecosystems, biogeochemical cycling, history, geography and biodiversity.
Increasing the understanding of how the biosphere functions at different spatial scales: global, regional and local level and understanding of the effect of human activities on life-support systems.
