There are 6 billion, 800 thousand
people in the world.
How many trees do you think there are
in the world?
You might say – “that’s a really
tough question – how in the world can anyone count how many trees there are in
the world?”
Well, thanks to NASA, we can actually
have a pretty good idea of how many trees we have here on planet Earth.
Trees reflect sunshine in very
particular patterns. This makes it
possible for NASA’s satellites to map and count strips of land where trees are growing. Biologists can then sample those places —
forests, suburbs, city parks, even city streets — assume a tree density,
multiply by acre or hectare, and calculate the number of trees.
In 2005 the scientists estimated that
there are over 400 billion trees in the world.
Ecology professor Nalini Nadkarni of
The Evergreen State College in Washington ran the numbers and calculated that
in 2005 that worked out to be about 61 trees per person.
Today, assuming about the same number
of trees, the number works out to be just over 58 trees per person.
Fifty-eight trees. Sounds like a lot of trees doesn’t it!
But, think about how we use trees, or
the products that trees produce for us, and we have to wonder, is it really a
lot of trees per person?
Well, there is the obvious use of burning logs in a woodstove
to heat a home in winter, or making the paper we use in our homes and offices
every day, but when Professor Nadkami had her graduate students write down a
list of things made from trees she got a list that almost never stops:
China uses over 45 billion – or about
45 per person. The whole world uses over
100 billion pairs per year.
So Japan, with roughly 1.7% of the
world’s population is using about 25% of the disposable chopsticks in the
world.
Actually, other than calculating the
wood used in chopsticks, it is pretty much impossible to figure out just how
much in total of the woody stuff is used every year by we Homo Sapiens.
It all sounds like a pretty sad story, doesn’t it? All of us humans cutting down all of those
trees for our own selfish needs?
The Indian poet, Rabindranath Tagore
said:
Trees are the earth's endless effort
To speak to the listening heaven.
So now, back
to my earlier question; are we humans
truly “wise and knowing men and women”?
Or, should
we best listen to the words of John Muir, the Scottish born American
naturalist who is well known for advocating preservation of the wilderness in
the United States when he said, “God has cared for these trees, saved them from
drought, disease, avalanches, and a thousand tempests and floods. But he
cannot save them from fools.”
