Globalization has helped society optimize consumption of food products. A huge and complex system of food trading has grown with time and its replacement seems unrealistic. However, km-0 or local consumption has arisen as a counterpart, to protect both local products and producers, but also, as a form of climate change mitigation. This concept consists of consumption of locally produced and seasonal products.
It is possibly a more responsible and respectful system with the environment. But, is it efficient in climate change mitigation? Is it economically sustainable? Are we willing to stop consuming certain products that cannot be grown locally?
Some side problems would also arise from switching to a km-0 system of consumption: how can societies that inhabit in rougher climates –which cannot produce much– have a quality diet in this system?
