that pollution caused by transporting goods was a major externality in a global economy, and one that "localvores" could greatly diminish. Also, environmental issues can be addressed when decision-making power is held by those affected by the issues instead of power sources that do not understand the needs of local communities. Political philosophy Localism as a philosophy is related to the principle of subsidiarity. In the early 21st century, localists have frequently found themselves aligned with critics of globalisation. Variants of localism are prevalent within the Green movement. According to an article in International Socialism, localism of this sort seeks to "answer to the problems created by globalisation" with "calls to minimise international trade and to seek to establish economies based on ‘local’ self-sufficiency only."

He eventually wrote a book by that name: All Politics Is Local: And Other Rules of the Game. Localism and populism Wayne Yeung questions the assumption that localism is a sub-school of European-American populism. Yeung raised an example in which localism is a cultural or civic value rather than a value that supports ethnic understanding in Hong Kong identity politics. Jane Wills argued that an increasing numbers of populist politicians are endorsing localism as a framework for public policy. She defined populism as a form of politics that involves people speaking in a register that is authentic to the experiences and needs of those people. In other words, most likely Populist Party policies would contradict parties that support the elites. She also used the term "anti-politics" to describe localist politicians because they stand against
