- 4. 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. (Produced by Trees in Danger, 45 Jacob Street, Birmingham 9) .
