Where+it+is+at+its+worst

=__Where acid rain is at its worst:__ = =    Acid rain affects forests and trees the worst. Over the years, scientists, foresters, and others have watched some forests grow more slowly without knowing the reason why. The trees in these forests were not growing as quickly as usual. Leaves and needles turn brown and fall off when they should be green and healthy. Researchers suspect that acid rain may cause the slower growth of these forests. But acid rain is not the only cause of these conditions. Other air pollutants, insects, diseases and drought are some other causes that harm plants. Also, some areas that receive acid rain show a lot of damage, while other areas that receive about the same amount of acid rain do not appear to be harmed at all.  Acid rain is at its worst in Scandinavia with many lakes with acidic water containing no life and many trees dead, many parts of the United States like New York are also very badly affected as well as places like Sweden, Poland and Czech Republic have areas that are affected badly. China is also very badly affected because of its high pollution levels. =
