Some 25,707 signatures in a petition is urging Philippine Pres.
Rodrigo Duterte to save the Philippine pine tree (Pinus insularis) in
the city of Baguio, dubbed as the “city of pines”.
The petition,
penned by this writer bwho is also head of the environmental group
Cordillera Ecological Center, raises the alarm on the wanton and
unjustified killing of pine trees to accommodate hotels and business
establishments. The city is the country’s summer capital, visited by
millions of tourists yearly because of its cool climate brought about by
the pine trees.
“Four pine trees provide oxygen for one person as
much as 45 lbs of oxygen a year. One pine tree absorbs as much as 40 t0
45 lbs of dangerous CO2 annually and cleanse the air of smog. One
mature pine tree absorbs as much as 150 liters of water which it
releases to recharge groundwater, Pine trees prevent landslides and
erosion, regulate urban island heat phenomenon and lessen wind speed by
15 percent,” the petition stressed.
Pine trees are heritage trees of the country, without pine trees there will be no city mof pines, “ it added.
Pinus
insularis, ever proud and conquering, is symbol of the Cordillera
peoples. Whether blanketed in lush cloaks of vibrant green or stripped
naked with only their bare trunks remaining, they reveal their beauty
throughout the warmest, wettest or rainiest seasons. Their knowledge of
time, history and events is timeless and though science, technology and
capitalism seem to have combined to end their reign, they continue to
remain.
On the surface, what most people see is the economic side
of pine trees—lumber for housing, furniture and buildings. Very few are
aware of the ecological, social, medical and cultural contributions of
pine trees.
What Do the Pine Trees Do?
As
food, pine trees seem unimportant to humans except for birds, insects
and a few animals. While some pine tree species’ have seeds big enough
to eat, Pinus kesiya’s seeds are, although edible, too small to really
satisfy human hunger. Only the Lebanese pine, Korean and Pinon pine have
seeds big enough to be harvested for food.
But the trees are
more important for something else. There are four direct and uncontested
facts that the pine trees do for the Philippine environment. First, the
trees help directly contribute to oxygen supply to the environment for
humans to breathe, directly affecting local and regional air quality by
altering the urban atmospheric environment.
Humans breathe only
oxygen which comprises 21 percent of our atmosphere. But oxygen in many
parts of the world is being depleted due to pollution wherein dangerous
methane, sulphur and nitrous oxides and CO2 and smog are increasing in
the air. Trees supply about 70 percent of our oxygen supply.
Second,
they provide water, absorbing as much as 150 liters per mature tree
each year which they release slowly to recharge brooks, springs, rivers
and ponds. Three of the nation’s biggest mega-dams, San Roque, Ambuklao
and Binga generating a combined 1,200 megawatts of hydroelectric
power—get their water from pine forests of Benguet and Mountain
Province.
Third, the pine trees prevent soil erosion and
landslides in the region, serving as the main soil cover thereby
protecting soil loss. The Cordillera region losses some 100,000 tons of
topsoil every year, without the pine trees soil loss would be worse
affecting adversely agriculture, settlements, properties and lives.
Fourth, pine trees lower temperature. When Baguio had more pine trees,
the city was cooler; it deserved to be called the “City of Pines”.
Today, the city is not only warm, congested and dirty but also dubbed by
World Bank as having one of the cities in the world with the “dirtiest
air” as thousands of trees were allowed by the city government to be cut
to give way to commercial and residential buildings, roads, tourism and
hotels.(On the surface, what most people see is the economic side of
pine trees—lumber for housing, furniture and buildings. Very few are
aware of the ecological, social, medical and cultural contributions of
pine trees.
Oxygen Supply and CO2 Absorption
One mature
pine tree, ten years and above, releases 45 lbs of oxygen a year. At
least four trees can supply the oxygen requirement of one human each
year.
As pine trees release oxygen, they absorb CO2, a dangerous
greenhouse gas. Each mature pine tree absorbs 45 lbs of CO2, following
physics’ Boyle’s law of “what element is lost is equally replaced by
another element”.
The oxygen released by the millions of pine
trees affect air by reducing temperature, remove smog and air
pollutants, CO2, methane, sulphur and nitrous oxides thereby regulating
microclimatic effects like cooling.
Pine Trees Lower Temperature
Clumps
of pine trees and all trees for that matter reduce mid-day temperature
from a minimum of 0.2 degrees C to 1.3 degrees C some 1.5 meters to 2.4
meters above ground.
Below individual and small fragments of pine
trees over grass, mid-day air temperatures can be reduced to as low as
0.7C to 1.3C degrees cooler than in any open area.
When pine
trees respire, they emit oxygen which do not only reduce air
temperature, but also absorb radiation and store heat. They also reduce
relative humidity, turbulence, and surface albedo of concrete. These
changes in local meteorology alter pollution concentrations in urban
areas.
Removal of Air Pollutants
Even though pine trees
leaves are needle-type, they function as normally as a broadleaf. The
needles through their stomata, remove deadly gaseous air pollution
primarily by uptake.
Once inside the leaf, gases diffuse into
intercellular spaces and may be absorbed by water films to form acids or
react with inner-leaf surfaces. The trees also remove pollution by
intercepting airborne particles. Most particles like CO2 are absorbed
into the tree, and eventually stored in the soil by the roots.
Some particles that are intercepted are retained on the plant surface.
These are resuspended to the atmosphere, washed off by rain, or dropped
to the ground with leaf and twig falls. Consequently, vegetation is only
a temporary retention site for many atmospheric particles.
Reducing Urban Island Phenomenon and Temperature on Buildings
Urban Island phenomenon is the heat transferred from cities via highway
and roads to outlying communities. Pine tree reduce this, as well as
lessen building energy use by lowering temperatures and shading
buildings during the summer, and blocking winds during rainy season.
When building energy use is lowered, pollutant emissions from power
plants are also lowered.
The cumulative and interactive effects
of trees on meteorology, pollution removal, and power plant emissions
determine the overall impact of trees on air pollution.
Energy and Medical Relevance
Pine
trees are the most popular among all conifers in the world, the most
widespread, most varied and most valuable trees of their order. The
biggest family of conifers goes by their name, the Pinaceae.
Pine trees are called pine trees basically because it contains the rare
and highly expensive Alpha e-pinene chemical content that the tree
treasures. E-pinene contains an important hydro-carbon alkane, the
chemical used for lighting and cooking in high altitudes and also
ingredient for pharmaceuticals and chemical necessities.
The
chemical is contained in the resin of the pine tree which explains why
pine wood is highly flammable. The indigenous Cordillera tribes make use
of resin-rich pine wood as flint or for starting fires called locally
“saleng”.
Pine Trees and the Joy of Christmas
There was a
time when pine trees were favorite trees cut for Christmas trees. Today,
cutting a pine tree is a crime. But pine trees still exude mixed joy on
Christmas especially to children. Thousands travel every Christmas to
Baguio City and other places in the Cordillera region just to see pine
trees.
To any young child who sees a small young pine tree, if
anything, he/she is fascinated with joy to reach out and touch the
vigorous plant– fantastically rich in its detail, with its thick and
sappy shoots bristling, bright new needles, embossed with male and
female parts of splendidly original and suggestive design– inviting kids
to dapple them.
The trees’ genus Pinus is the pine proper,
limited to 100 or so species all over the world, with certain clear and
obvious characteristics, of which the easiest to see and remember is the
relatively long evergreen needles.
The pine needles and cones
are the ones that easily lure people on Christmas time. Pinus kesiya has
three needles for each fascicle. The yearly growth of each shoot of a
pine needle takes the form of a ‘candle’, which is a defiance of
gravity.
The needles are boiled as tea and drank to cure upper
respiratory tract ailments. Medical experts recommend to asthma victims
to walk under pine trees in the morning because the trees release
terpenes which help cleanse the lungs.
Thanking the Pine Trees
To
give thanks to the pine trees for their ecological, social, cultural,
economic and aesthetic benefits, the environmental group Cordillera
Ecological Center conducts yearly the Pine Tree Festival. Already on its
fourth year, educational, cultural, music and arts activities by
representatives from Baguio city, Benguet, Mountain Province, Abra,
Kalinga and Apayao. It attracts thousands of tourists.Most importantly,
it advocates and leads numerous tree planting activities.
Next
time you find yourself walking underneath pine stands, woods or forests,
look up. Not many people embrace this view high above our limited
ground floor. An awakening and soul-changing world is gifted by a simple
tilt of the head as you see the sky through a beautifully complicated
and tangled web of pine trees.
