Indian activist and scientist, Vandana Shiva, for example, shows in her book Stolen Harvests (South End Press, 2000) that those who are often beneficial to the environment have been forced into poverty due to politics and economics such as concentrating land rights, pressure from industry to use the environment for other purposes or in other ways, etc. Industrialization is often to blame for losses in diversity. Excessive debt burden means that it becomes harder to sustain the environment.
