Macro-engineering
（重定向自Macroengineering）
In engineering, macro-engineering (alternatively known as macroengineering or macro engineering and as mega engineering) is the implementation of extremely large-scale design projects. It can be seen as a branch of civil engineering or structural engineering but just on a very large land area. In particular, macro-engineering is the process of marshaling and managing of resources, technology and public opinion on a large scale to carry out complex tasks that last over a long period.
