include existing and new trees
(preferably native species), rain
gardens, green walls and green
roofs. Trees, especially large ones,
bump up the score considerably.
Globally, an estimated three
trillion trees dot the earth. That's
more than 400 trees per person.
Against their continuous loss,
American citizens and forest
product companies plant about 1.6
billion trees a year, according to
GreenandGrowing.org. The more
trees we plant, the less environmental
damage there is to repair, with fewer
severe heat waves and less intense
urban heat islands. Foliage provides
cool " micro-climates " in hot cities.
With less competition than in a forest,
trees grow much bigger in cities.
The thermal impacts of trees are
not trivial, even in our cool climate.
According to the U.S. Department
of Agriculture, the cooling impact of
a single healthy street tree is equal
to 10 room-size air conditioners
operating round the clock! As deadly
heat waves become more common,
shade becomes a civic resource,
returning our bodies to more
normal equilibrium. Temperatures

on exposed streets compared to
canopied ones tend to be anywhere
from 5° to 15° F cooler, according
to National Geographic.
Jeff Speck writes in his book 
Walkable City that streets made
cooler with trees help people
vulnerable to heat stress and
exhaustion, such as outdoor workers,
the homeless and the elderly. He
feels that shade can be a matter of
life and death.
There are also significant
economic benefits, both to individual
homeowners and to the cities they
live in. A study at the University of
Pennsylvania found that a single tree
planted near a house raised its value
7% to 11%. According to a 2017 issue
of Yale Environment 360, trees in 10
megacities around the world save
$500 million per year in heat costs,
energy expenses and environmental
protection. They reduce air pollutants,
reduce storm water run-off and air
conditioning costs. Another study -
joint between UC Davis and the U.S.
Dept. of Agriculture - determined that
in the wet Pacific Northwest, a tree
saves $3,000 per year! In 2014, Olaf
Ribiero on insidebainbridge.com wrote

that over a 50-year lifespan, a tree
generates $161,000 in total benefits,
while releasing enough oxygen to
support two humans.
Trees are an immense breathing
system for the earth that is essential
for both plants and animals,
including humans. They breathe
out what we breathe in; we breathe
out what they breathe in. They do
much to combat climate change
- from street trees to the giant
Amazonian Rainforest, the lungs
of the earth. Urban trees are like
little hospitals, enhancing microclimates and making us feel better
psychologically and physically. It's
no wonder that we love them. The
earth needs more trees. Humans
need more trees. Cities need more
trees.
My wife and I are currently
planting one new tree and moving
some small trees at our Seattle
home. As I type, I can hear the
aerial tree man's buzz saw thinning
an existing pine tree, soon to move
on to pruning five more trees. Our
trees are becoming healthier and
more beautiful, while making us
healthier.
