ich muss ein Kurzreferat über Waldsterben halten und habe mir dafür ein paar Notizen aufgeschrieben.Allerdings bin ich in Englisch leider sehr schlecht
Dying of forests
Introduction
-30 % of the german area are woods
-was in the 80s a current topic:in 20 years woods will died
-20 years later: almost no one is interested on the topic of the dying forests
-but:necessary for our life ,because they proctudes oxygen( Sauerstoff)
A pair of causes:
- air pollution: -cars and factories produce polltutans :e.x.:sulfor dioxide
-polltutans comes with the rain as “acid rain” on the land
2.to much nitrogen (stickstoff):
-come from farmers :-trough factory farming(means –to much animals one one place)
-put on their fields to much nutrients (Nährstoffe)
-trees grows up to quickley-but roots (Wurzeln) are not ready: storms kill the trees easier
3..insect:
-ill trees can not resist against the insect
-e.x:bark beetle (Borkenkäfer)-can kill whole forests
What can we do against?
-put calcium over the trees against acid rain
-do not have factory farming
-reduce the pollution from cars and factorys
-do not fly if it is not necessary and use more often our bike
