A huge movie buff I am. I can see any good movie from any land, preferably with subtitles rather dubbing (which kills the original art phonetically I think). From the various videos and documentaries I have seen, I pick 13 of the best movies falling in the nature/environment genre, I can remember.

The Cove: Depicting the stress suffered by the animals in captivity?how a dolphin committed suicide!

Baraka: A visually stunning photographic documentary on the most beautiful things to be seen on earth. I couldn't see the whole thing in one sitting due to amazement depicted.

Earthlings: Hidden cameras show some of the inside secret practices of the industrial world.

Home: Aerial footage from 54 nations and the interlink-age of all the planet?s problems.

Winged Migration: Migratory birds behavior shot over three years span on the seven continents.

Who killed the Electric Car? : A classic documentary telling the life and death story of the electric car.

Food, Inc. : Perhaps the most popular movie on the inside food industry activities.

Sharkwater: One of the best movies on the amazing ocean world.

Encounters at the End of the World: A perfect movie on Antarctica.

Earth: The migratory world of four animal families.

The 11^th Hour: A documentary focusing on restoring the ecosystems.

GasLand: Rural American story of how the landowners are lured by energy corporate.

An Inconvenient Truth: The most popular and widely known film on global warming and Al Gore's campaign.

PS: No Ranking is done with the order of movies in the above list. I may not be remembering other good films seen in the genre. Please share in case anyone loves movies of this genre. :)
