This chapter introduces the politics of the Earth, which has featured a large and ever-growing range of concerns, such as pollution, wilderness preservation, population growth, depletion of natural resources, climate change, biodiversity loss, and destabilization of the Earth system. It explains how the issues of Earth’s politics are interlaced with a range of questions about human livelihood, social justice, public attitudes, and proper relation to one other and other entities on the planet. It also discusses the consequences of discourses for politics and policies. The chapter clarifies how environmental issues like ecological limits, nature preservation, climate change, biodiversity, rainforest protection, environmental justice, and pollution are interconnected in all kinds of ways. It develops an environmental discourse analysis approach and shows how this approach will be applied in subsequent chapters, beginning with the positioning of environmental discourses in relation to the long dominant of discourse of industrialism.
