In a world of increasing globalization, environmental concerns must contend with a variety of geopolitical borders for policy solutions. More than ever, environmental practitioners and students work in a global community, where the challenges of one nation impact worldwide issues that interconnect to other issues like poverty, human rights, and quality of life. During my trip two years ago to China, where I was invited to speak on international environmental treaties, particularly the Kyoto Protocol, I was struck by the global impacts from local practices in our megacities across the planet. The phrase by the United States (US) Environmental Protection Agency of “act locally and think globally” does not capture the magnitude of impacts from our large, dense megacities that collectively as urban dwellings are changing the quality of life of places on the globe much farther away. This poses new challenges for environmental professionals implementing projects and for academics teaching environmental public policy and sciences. The challenge is to expand both the professionals' and the students' understanding of not just of the environmental impacts to a region or state, or even nation, but also the sociocultural and economic ramifications of environmental impacts globally. In that spirit, Environmental Practice has focused our issues of 2013 on international environmental issues, beginning with our March issue on the European Union (EU). Continuing in the international theme, this issue of Environmental Practice is devoted entirely to the environmental challenges faced by China—with regard to the US, as well—for environmental issues today.
