To paraphrase a line of poetry by "Winnie Aumonier":
"When the world wearies & ceases to satisfy, there is always nature". (Winnie Aumonier's actual wording was "When the world wearies & ceases to satisfy, there is always the garden".)
And how does Nature handle stress. For one porcupine, perhaps some ideas.
(These photos were taken in an area that requires an hour (one way) walk through a deserted provincial park, as all Alberta Provincial Parks are now closed to traffic.)
