There's one estimate which suggests that in the United States, two thirds of the land which was once forested and then cleared has become reforested as loggers and farmers have retreated, particularly from the eastern half of the country.
Há uma estimativa que sugere  que nos Estados Unidos, dois terços das terras que um dia  era florestada e foi desmatada se reflorestou quando lenhadores  e fazendeiros recuaram, em particular da metade oriental do país.
