biosphere
all ecosystems
environment
All external conditions and factor, both living and non-living that affect an organism during its lifetime. Doesn't have internal.
environmental studies
The study of how both we and other species interact, with each other and with non-living environment. It has both physical (science) and social aspects that integrate knowledge from many fields.
