This chapter addresses the interactions of individuals with government, business, and other institutions to build upon and support individual efforts. It emphasizes sustainable outcomes at regionally and globally significant scales. Global changes that threaten Earth’s ecosystems and society could be reversed through progress toward four key stewardship goals: reducing atmospheric concentrations of greenhouse gases, increasing the extent of forests and wetlands, sustaining ecosystem services, and reducing human population growth and unnecessary consumption. The US Declaration of Independence radically included “pursuit of happiness” as an inalienable right of all people. Since happiness is generally unrelated to consumption or wealth, society’s happiness and well-being can often be enhanced without increasing consumption. The chapter outlines five potential strategies by which government can complement the efforts of individuals to foster happiness. If people decide, individually and collectively, that the planet’s future habitability is important, they will know how to ensure a better life for their grandchildren.

Abstract In light of recent alarming trends in human population growth, climate change, and other environmental modifications, a “Warning to humanity” manifesto was published in BioScience in 2017. This call reiterated most of the ideas originally expressed by the Union of Concerned Scientists in 1992, including the fear that we are “pushing Earth's ecosystems beyond their capacities to support the web of life.” As subterranean biologists, we take this opportunity to emphasize the global importance and the conservation challenges associated with subterranean ecosystems. They likely represent the most widespread nonmarine environments on Earth, but specialized subterranean organisms remain among the least documented and studied. Largely overlooked in conservation policies, subterranean habitats play a critical role in the function of the web of life and provide important ecosystem services. We highlight the main threats to subterranean ecosystems and propose a set of effective actions to protect this globally important natural heritage.

As freshwater resource decreasing rapidly due to high rate of human population growth, many researchers have done studies to develop methods for producing freshwater supply. Seawater desalination is one of the method that has the credibility to be implemented. However, conventional seawater desalination processes suffer from a number of problems related to energy efficiency and cost. In spite of this, nanotechnology has been applied to the process. In this paper, we give an overview and explanations concerning the roles of nanotechnology in seawater desalination processes which consist of pretreatment, reverse osmosis (RO), and disinfection. In addition, the comparisons between conventional and nanotechnology-applied processes as related to its efficiency and effectiveness are also provided.
