[解题导语] “环境一直在变坏，我们的星球末日将要来临”，这是环保主义者们发出的警告，然而Lomborg的新书却提出了完全相反的观点，他批驳了环保主义者们耸人听闻的言论。

A．Our planet is in bad shape.
B．The world's environment is improving.
C．The total amount of forests in the world is not declining.
D．Conservation efforts have been successful.
解析：考查细节理解。根据文章第一段与第三段可知Lomborg在The Skeptical Environmentalist中的观点(argument)是环境状况正在改善，因此选项B正确，C项只是他观点的一部分，不全面，故排除。
答案：B
