The Biggest Myth About Buying Local Food
Wrong. Let's delve a little deeper.
Proponents of local food are absolutely correct in saying that closer production reduces the carbon impact of transportation, but transportation is not the only facet of food production that releases greenhouse gases, which contribute to climate change. In fact, it's actually a pretty paltry one. Production accounts for the vast majority of agriculture's carbon footprint, while transport to the grocery store, and finally your table, accounts for less than a tenth! This value varies depending upon the foodstuff, ranging from a low of 1% for red meat to a high of 11% for fruits and vegetables.
This means that buying local really doesn't have much of an impact on climate change. In fact, in a 2008 paper, Carnegie Melon University's Christopher Weber and H. Scott Mattthews calculated that if a family reduced all of their "food miles" to zero -- basically meaning they grew all of their own food in their kitchen (good luck with that mess) -- the reduction in carbon impact would be equal to driving a 25 mile per gallon car 1,000 miles less per year. The frugal SUV driver would be making a more eco-conscious sacrifice.
Considering that production accounts for such a significant chunk of the energy that goes into food, there are actually many circumstances where buying local can actually be worse for the climate.
"For example, an acre of land in Idaho can produce about 50% more potatoes than an acre of land in Kansas," Steven Novella, president of the New England Skeptic Society, pointed out on a recent episode of The Skeptics' Guide to the Universe. Buying a local potato in this circumstance would be quite inefficient.
Moreover, for eco-conscious lamb consumers in the United Kingdom, it actually makes more sense to purchase lamb raised 11,000 miles away in New Zealand than lamb raised down the street. Why?
"New Zealand sheep are generally pastured and raised on farms using hydroelectric power," wrote Gary Adamkiewicz, an environmental scientist at Harvard."

Advice when shooting a time-lapse
essential to use long shutter speeds of between 1/3 and 3s
moving plants, especially when they are in the foreground, look horrible in time-lapse.
care about framing, composition, light, and the subject
over-retouching with aggressive process with surreal textures on buildings and dramatic skies
Not all the videos made with time-lapse must have a epic track, or use the music of the famous Icelandic band Sigur Rosnever upload your video to Youtube. The image quality...is terrible and the compression applied to the videos is very high...upload it to Vimeo, where the quality is pretty good and you will get in contact with a community of filmmakers
