Discussions of "health" by the international community invariably imply human health and exclude any reference to animal health, plant health, soil health or health of other entities. And with respect to health, the meaning is usually further restricted to physical health, and excludes emotional health, psychic health, spiritual health, community health, [etc]. With respect to physical health, many mammals suffer from the same diseases as humans but reference to these diseases is normally restricted to humans, for example tuberculosis, cancer, rheumatism, blindness [etc]. Ironically animals are however used to test remedies for these exclusive human illnesses which are subsequently applied to humans.
The term "environmental stress" is appropriated by environmentalists to refer to the natural environment and excludes any connotations in relation to the psychological or social environment of human beings.
