\nIn this presentation I aim to sketch the general trajectory of environmental change in the last century and to explain why that trajectory followed the course that it did. First I will try to provide a quantitative sense of the dimensions of several kinds of environmental changes, all on a global basis. This includes changes in land use and land cover, air and water pollution, water use, biodiversity among other categories. What follows is an effort to explain what social, economic, and political trends have been most consequential for environmental change, which involves discussion of energy systems, population, politics, and technology, among others. Several regional and local examples, ranging from Soviet industrialization efforts to the implications of chains saws, relieve the otherwise relentless attention to global-level analysis. \n
