Some idea about our planet earth... --------------------
The basic idea is good the book bad...
The auther is right. Its the right way to respect nature and live in concord with her.
But in the book there are some wrong comparisons and the aver that the nature is more intelligent then the men is wrong, too.
Because, that would mean that nature needs intelligence to be so perfect how she is. But its not intelligence what the nature(on earth) makes so perfect...its the best possible adaptation to the circumstances on earth, with the for nature available tools. That is what the nature makes just perfect, not intelligence.
