In the 1970s, the highway revolts in some Western nations saw urban activists opposing government plans to demolish buildings for freeway route construction, on the basis that such demolitions would unfairly disadvantage the urban working class and benefit commuters. Anti-nuclear protests against proposed nuclear power plants in the United States and Germany prevented developments due to environmental and social concerns.
Megaprojects have been criticised for their top-down planning processes and their ill effects on certain communities. Large scale projects often advantage one group of people while disadvantaging another, for instance, the Three Gorges Dam in China, the largest hydroelectric project in the world, required the displacement of 1.2 million farmers.
