International relations affects everyone's lives: their security, economic well-being, rights and freedoms, and the environment they share. Recently we have seen the transformation from a world of empires to today's world of sovereign states, which are enmeshed in a complex array of international institutions, all exercising degrees of political authority. The new global organization of political authority has far-reaching consequences. This audiobook untangles this complex world, providing an accessible framework for understanding the contours of global political change.

But many scholars believe that political leaders rarely act rationally. The issue is crucial for both the study and practice of international politics. John J.

Conservationist Rachel Carson spent over six years documenting the effects on DDT, a synthetic organic compound used as an insecticide, on numerous communities. Her analysis revealed that such powerful, persistent chemical pesticides have been used without a full understanding of the extent of their potential harm to the whole biota, including the damage they've caused to wildlife, birds, bees, agricultural animals, domestic pets, and even humans.
