Migration, population and climate justice are highly emotional topics already the subject of much detailed writing, with many good texts. However, less is written using a particularly anarchist analysis of how they link-up. Thus, we do not go into exhaustive detail on these issues but to demonstrate a) how they are all inter-connected; and b) how an anti-authoritarian critique of the underlying issues and prevailing attitudes can help build communities of resistance and solidarity. We hope that as well as filling this gap, this pamphlet will be a starting point for various debates that still need to be had. We hope that the range of topic and treatment of issues will provide materials to satisfy every reader, whether those new to anarchism or those well versed in the standard texts. Half the articles appear for their first time in this publication; the rest are a selection of texts which we felt were valuable contributions to the debate or demonstrated the solidarity and awareness we are calling for in action.
