TREES IN DANGER
Millions of year before animals lived on land; there were trees on
the Earth. But today trees are in serious danger.
In the 1970´s many of the el trees in Europe were killed by Dutch
elm disease. Now an even greater danger is threatening the
forest and woods of Europe from northern Sweden to southern
Italy. This new danger attacks all trees: deciduous trees like oak,
beech and birch as well as coniferous trees like fir and pine.
First, the branches turn yellow and brown.
Then, the trees ´needles or leaves fall. The roots and the trunk
shrink, finally the trees die.
But, what is killing the trees? Nobody knows exactly, but it is
probably air pollution or acid rain. Factories, power stations and
cars emit tons of smoke into the air. This smoke contains
sulphure dioxide and nitrogen oxide. These substances mix water
vapor in the atmosphere and form sulphure acid and nitric acid.
Sunlight turns these acids into poisonous oxidants which fall in
rain or snow onto the trees.
Trees are important because they provide a home for other
plants, and animals too. They produce protect the flowers which
grow on the forest floor. They provide food for insects, reptiles,
birds and mammals. They protect the soil from the wind and the
rain. Most important of all, the forest are the lungs of the planet.
Trees produce the oxygen which we breathe. If the trees die, we
will too.
