Although Time to Change was originally published in 1994, the topics of environmental problems still remain current. Over time, people have become more aware of the problems caused by overpopulation, industrialization, the depletion or corruption of natural resources and the impact on flora and fauna, however the problems have not been solved.
While some of the experiments mentioned by Suzuki were completed with mixed results, the cause and effects of man's impact on nature and the poor response for funding and political support by government and businesses still remain a problem.
Suzuki's inclusion of stories of his past, and trips with his family, makes this a lighter book to read, getting the issues across to the reader, without bogging down the topics with overwhelming statistics and graphs.
