Save the Trees
The Problem
Key Concepts Addressed
The trees on our planet are being depleted
at an alarming rate. Some experts
estimate that more than fifty percent of
Earth’s trees have disappeared due to
human activity. Trees are a vital part of
our planet’s survival. A mature, leafy tree
produces a substantial amount of oxygen
for humans and animals to breathe.
Trees, in essence, act as filters that clean
the air we breath. As it produces its food,
a tree absorbs carbon dioxide and uses it
during the process of photosynthesis.
Oxygen, one of the products of this
process, is released into the atmosphere.
According to the British Columbia Forest
Association, 100 trees absorb
approximately five tons of carbon dioxide
and one thousand pounds of other
dangerous pollutants during their lifetime.
Carbon dioxide is toxic to the human body,
so it is very important that trees exist to
remove it from our atmosphere.
Photosynthesis is a chemical reaction that
occurs in plants. During this reaction,
radiant energy from the Sun, carbon
dioxide absorbed from the atmosphere
and water absorbed from soil are
transformed into chemical energy in the
form of a sugar called glucose. Oxygen is
also produced and is released into the
atmosphere.
