i saw this movie with my family and it be great . this film be more than just a documentary ( that offer not more than cold fact ) with long mono or duologue and lot of chart . the complete power of this movie come from the impressive picture be film under water and in the air or the arctic . with watch this movie you can learn more about our planet than with just read a book and it show that we be embed in the circular flow of life . this movie be not only for environmental fanatic although people that want to look a good movie with a message should watch it . this movie teach me that we be not only live on the earth . we live with and through the earth and all plant and animal grow and die with u .
