This is an interesting video and should be shown at schools ect. as someone else stated in a review. I watched it in hopes of picking up a tip or two for my home garden. Digging in the soil is enjoyable to me, although I feel the need to wash right away. There must be a better way, can you say hydroponics. Not sure of proper spelling but plants will grow just fine in water, so long as supplied with nutrients. Guess that is off topic of this film. Not everytihing stated in this film is true, but still a decent watch. For some reason I kept thinking birth control throughout.
