Global Eye is a (now defunct) magazine aiming to bring global issues to primary and secondary schools. Thus, the language is pretty accessible and a lot of it could be used with English language learners. As a magazine, the materials are primarily readings and pictures / graphics, but there are some writing activities in there, too. I found the website a little tricky to navigate, but the index of past articles (broken up into countries and themes) is a good place to start. Another good place is the collection of pdf copies of the old magazine. Even though this website is no longer being updated, it’s a good source of introductory readings on a number of countries and issues.
