When plants and flowers grow abundantly - when all nature is strong and healthy, then your own health is secured
If however nature is weak or ill, if plants and flowers die or grow slowly, then your own health is at risk. Nature is an indicator of the natural balance around you. Keep natural environment around you growing jungle-like and regard nature as an indicator and early warning system for yourself. If nature gets ill around you, then your own health soon may get damaged as well.
Act before you may get forced to be hospitalized. If nature gets ill, move into less crowded, less industrialized environment. You have but one body, one health to maintain for all life - you have but one single nature for all planet for ALL ETERNITY. Learn to observe your neighborhood as well as your own inside. Learn to adjust before ill environment adjusts you.
