Why it matters
A vibrant, diverse local economy is a healthy and resilient economy. Meeting local needs locally can mean less pollution and CO2 emissions from unnecessary transport, as well as providing economic opportunities. Some have tried to argue that this approach is anti-trade, whilst its supporters contend it is just anti dependence on trade.
"...the best hope for transition to a ‘post carbon’ — or, better, a sustainable society (a much broader goal) — lies in a process of radical societal reconstruction, focused on the building, in the here and now, of self-governing and self-reliant settlements, starting at the micro-local level. Jonathan Rutherford, summarising from Ted Trainer 
“Every increase in local capacity to grow food, generate energy, repair, build and finance will strengthen the capacity to withstand disturbances of all kinds. Distributed energy in the form of widely disbursed solar and wind technology, for example, buffers communities from supply interruptions, failure of the electrical grid, and price shocks. Similarly, a regionally based, solar-powered food system would restore small farms, preserve soil, create local employment, rebuilt stable economies, and provide better food while reducing carbon emissions and dependence on long-distance transport from distant suppliers. The primary goal in rethinking development and economic growth is to create resilience – capacity to withstand the disturbances that will become more frequent and severe in the decades ahead”. David Orr, ‘Down to the Wire’

Local Futures (formerly the International Society for Ecology and Culture) is a non-profit organization whose purpose is to raise awareness about what it identifies as the root causes of contemporary social, environmental and economic crises.
The group argues that focusing on single issues – saving whales, blocking nuclear power plants, feeding the hungry, etc. – only overwhelms people and ultimately fails as a strategy. Instead, Local Futures believes that the focus must be on changing the fundamental forces that create or exacerbate all of these problems. Among those forces are economic globalization, corporate power, and conventional notions of technological and economic "progress". As a solution, Local Futures promotes economic localization and other locally based alternatives to the global consumer culture, as a means to protect both biological and cultural diversity. W
