Globalization is often discussed as if it were a recent phenomenon relating primarily to the development of world financial markets and improvements in information and travel technologies. But globalization is an ancient process, beginning with mercantile and cultural exchanges and facilitated by advances in transportation. In the twentieth century, the results of globalization can be seen in the rise of global capitalism and in the construction of a global economy. Most recently, the process of globalization has moved beyond the world of finance, however, into areas still traditionally thought of as national concerns, such as culture and healthcare. It is no surprise, therefore, that increasingly the challenges the United States is confronting in healthcare, biotechnology, and the environment are simultaneously faced by the international community as a whole. In the wake of the HIV pandemic, growing environmental consciousness, and a series of sensational advances in biotechnology, there is a dawning realization that problems such as improving public health, regulating advances in biotechnology, and achieving sustainable environmental development transcend national borders. In other words, bioethics concerns are global in nature.
