The book is out of date since it was written in 1970, but much of the information is still valuable. It is sad to see that many of the ecological problems that were identified 40 years ago have not been solved and that many negative predictions have come to pass. The world population has increased from 3.5 billion to 6.8 billion since 1970 (almost doubling as predicted). Problems associated with oil spills, air polution due to car exhaust, use of pesticides, species extinction, polution due to a lack of recycling and continued overpopulation have not been solved. The ecological problems have been mounting for some time (i.e., killing of bison in 1800s in the US, doubling of world population from 1850-1950). Unfortunately, it seems as though we as a species will continue to use up our resources until we sicken ourselves to death, like bacteria that overgrown in a petri dish. ( )
