We live today in an interconnected world in which ordinary people can became instant online celebrities to fans thousands of miles away, in which religious leaders can influence millions globally, in which humans are altering the climate and environment, and in which complex social forces intersect across continents. This is globalization. In the fifth edition of his bestselling Very Short Introduction Manfred B. Steger considers the major dimensions of globalization: economic, political, cultural, ideological, and ecological. He looks at its causes and effects, and engages with the hotly contested question of whether globalization is, ultimately, a good or a bad thing. From climate change to the Ebola virus, Donald Trump to Twitter, trade wars to China's growing global profile, Steger explores today's unprecedented levels of planetary integration as well as the recent challenges posed by resurgent national populism.
