i like watching a films. and my favourite film is " avatar", directed by james cameron.

to tell the truth, i have not seen anything more interesting and exciting in my life.the   film descibes the events of the year 2154.the story it advances the idea of care   for living beings and the nature as the only way to survive for the whole planet. it shows how cruel people may be. so everyone can make parallels to the ecological situation on the earth and the way people treat it.

to my point of view? this film is great!  

wild elephants have strong family ties. the females and young are social, living in groups under the leadership of an older female or matriarch. adult males are solitary, although they stay in contact with the females over great distances, using sounds well below the range of human hearing. family groups communicate with each other using these low-frequency vibrations. it is an eerie sight to see several groups converging on a waterhole from miles apart, apparently by some prearranged signal, when human observers have heard nothing.  the natural lifespan of an elephant, about 70 years, is comparable to a human's. elephants reach breeding age at about 15 years of age. females generally give birth to one 200-pound baby after a 22-month pregnancy.
