In recent years, vibrant social movements have emerged across the world to fight for environmental justice –- for more equitable access to natural resources and environmental quality, including clean air and water. In seeking to build community rights to natural assets, these initiatives seek to advance simultaneously the goals of environmental protection and poverty reduction. This paper sketches the contours of struggles for environmental justice within and among countries, and illustrates with examples primarily drawn from countries of the global South and the former Soviet bloc.
