Insect and disease issues are often specific to the Mediterranean forest systems rather than shared with the temperate forests. In addition to the specific native insects and diseases, the forests are subject to the invasion of exotic species. The forests are also at risk from high degrees of human activity, including changing patterns of forest fires, land management activities, intensive plantation forestry using introduced timber species from other Mediterranean climate zones, and atmospheric deposition. Combined with elements of global climate change that may disproportionately affect Mediterranean climate systems, this creates a number of significant management issues that are unique to the Mediterranean forests. It is our goal that the information contained in this volume will contribute to understanding the unique aspects of Mediterranean forest systems and to protecting these critical resources.
The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

The powerful, untold story of the 1950 revolution in Puerto Rico and the long history of U.S. intervention on the island, that the New York Times says "could not be more timely." In 1950, after over fifty years of military occupation and colonial rule, the Nationalist Party of Puerto Rico staged an unsuccessful armed insurrection against the United States. Violence swept through the island: assassins were sent to kill President Harry Truman, gunfights roared in eight towns, police stations and post offices were burned down. In order to suppress this uprising, the US Army deployed thousands of troops and bombarded two towns, marking the first time in history that the US government bombed its own citizens. Nelson A. Denis tells this powerful story through the controversial life of Pedro Albizu Campos, who served as the president of the Nationalist Party. A lawyer, chemical engineer, and the first Puerto Rican to graduate from Harvard Law School, Albizu Campos was imprisoned for twenty-five years and died under mysterious circumstances. By tracing his life and death, Denis shows how the journey of Albizu Campos is part of a larger story of Puerto Rico and US colonialism. Through oral histories, personal interviews, eyewitness accounts, congressional testimony, and recently declassified FBI files, War Against All Puerto Ricans tells the story of a forgotten revolution and its context in Puerto Rico's history, from the US invasion in 1898 to the modern-day struggle for self-determination. Denis provides an unflinching account of the gunfights, prison riots, political intrigue, FBI and CIA covert activity, and mass hysteria that accompanied this tumultuous period in Puerto Rican history.
