"God talks to human beings through many vectors: through each other, through organized religion, through the great books of those religions, through wise people, through art and music and literature and poetry, but nowhere with such detail and grace and color and joy as through creation. When we destroy a species, when we destroy a special place, we're diminishing our capacity to sense the divine, understand who God is and what our own potential is." Robert Francis Kennedy Jr., April 19, 2023, Boston Park Plaza Hotel, Back Bay, Boston, Massachusetts.
“And there’s many people out there who want us to move to the next planet already and I’m like, hang on, let’s not give up on this planet yet," William, Prince of Wales, July 31, 2023, Sorted Food food truck, London, England, United Kingdom.

Unitedstatesian structures and 32 percent, as 44-plus million, of Unitedstatesian housing bide in the full continuum of wildland-urban interface of rural lots to suburban, general-residential, urban-/town-center developments. Wildfire risk changes in wildland-urban interfaces even as the Fire Behavior Triangle clusters its aspect/shape/slope topography, temperature/precipitation/humidity/wind weather, arrangement/continuity/moisture/fine-heavy/condition fuels into the three-element fuel, heat, oxygen. All arborists deal with the critical, manageable fuel side of that fire-behavior environment even as their efforts decrease wildfire risk without downgrading it to zero percent.
Unitedstatesian activities effectuate 85 percent of Unitedstatesian fires even as healthy-landscape, healthy-vegetation commercial, community, municipal, utility arborists educate wildland-urban interface communities about endeavoring wildfire-fueling vegetation modification.
Fire-resistant principles fight against such dry wind-furthered embers as burning debris from motorized equipment and vehicles and unattended campfires, potentially more ignitable than wall-high, wall-wide flames.

Fire-resistant principles fight against such dry wind-furthered embers as burning debris from motorized equipment and vehicles and unattended campfires, potentially more ignitable than wall-high, wall-wide flames.
Ember intrusions into flammable materials, structural gaps and building vents generate major area-structure, area-vegetation risks even as small embers miles from wildfire sites goad combustible-material ignitions. Department of Agriculture Forest Service retired Fire Ecologist Jack Cohen houses his fire risk-reducing Home Ignition Zone in residential and other-use buildings and 5-foot (1.5-meter) surrounds. Defensible space, fire-resistant materials, ignition-prevention landscape design and potential ember-source reduction impel commercial, community, municipal, utility arborists to interrupt wildfire risk-impeding horizontal- and vertical-continuity fuel types.

ANSI (American National Standards Institute) Z133 safety standards and ANSI A300 wildfire-mitigating tree-care and management standards lead commercial, community, municipal, utility arborists through safe arboricultural practices. Chipped groundcover means moist decomposition even as their dying musters high, long flames and many embers from dry, tall forbs, grasses, shrubs and highly-flammable pine-/wheat-straw mulches. Pruning and removing wildland-urban interface trees nets increased light for increased understory-plant growth even as that increase nurtures fast-dried, "light and flashy" (Protecting:14), wildfire-nourishing woody plants.
