This is another fascinating TED I love, which inspires us to plant our own food. Moreover, you can find out "The history of Gastronomy in 15 seconds". Isues e.g. food crisis, population, obesity, hunger also are discussed by speaker in this video holistically.
Last but not least, more information about planting can be found out from "Kitchen Gardeners International - You can grow your own food. We can help" @ http://kgi.org/
