This introduction provides a broad critique of, and gaps in, the mainstream literature on environmental law from a global South perspective. It navigates through the development of environmental law at the international level and at the domestic level, and provides a critique from the point of view of countries and peoples in the global South. It argues that the domination of the global North is a continuing phenomenon although the strategies and tools may have changed over the decades. Indeed, (environmental) law is one of the tools through which domination and exploitation are exercised and legitimised. This introduction also introduces new approaches and bases on which environmental law needs to be rebuilt to serve the interest of the poor and the marginalised of present and future generations in both global South and North.
