TREES IN DANGERMillions 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.
