While you might assume that buying food from a local grower has a smaller carbon footprint than flying across the world on a plane, you're wrong.
Yes, a cargo plane produces greenhouses gases, but often a worse culprit is a small heated greenhouse, like the kind used to grow food on smaller farms found locally.
Nor are organic and "locally" grown food shops always as local as you might think.
A 2009 study of one of the UK's largest organic food distributors was carried out by scientists from the University of Exeter.
It found that a round trip in a car journey of more than 6.7 km will emit more carbon than the usual system of cold storage, packing, transport to a regional hub and final transport to a customer’s doorstep used by large-scale vegetable box suppliers.
'Organic farms are better for biodiversity'
People take "organic" to mean "pesticide free", and therefore synonymous with being critter-friendly.
Due to their lack of chemical engineering and pesticides to repel crop destroyers, organic farms need larger tracks of land to keep the yields up.
Proponents of organic food say this creates more biodiversity due to the larger farms.
However in places such as the tropics, the oversized farms can encroach upon rainforests, and even lead to their chopping down in order to make more room.
While there is a potential for this problem, the real extent of it should not be overplayed.
