Between 1960 and 1999, Earth's population doubled from three billion to six billion people. In many ways, this reflected good news for humanity: child mortality rates plummeted, life expectancy increased, and people were on average healthier and better nourished than at any time in history. However, during the same period, changes in the global environment began to accelerate: pollution heightened, resource depletion continued, and the threat of rising sea levels increased. Does the simultaneous occurrence of population growth and environmental decline over the past century indicate that more people translate into greater environmental degradation?
In The Environmental Implications of Population Dynamics, Lori Hunter synthesizes current knowledge about the influence of population dynamics on the environment. Specifically, her report examines the following:
The relationship between demographic factors — population size, distribution, and composition — and environmental change.
The mediating factors that influence this relationship: technological, institutional, policy, and cultural forces.
Two specific aspects of environmental change affected by population dynamics: climate change and land-use change.
Implications for policy and further research.
Hunter concludes that population dynamics have important environmental implications but that the sheer size of population represents only one important variable in this complex relationship. Other demographic dynamics, including changes in population flows and densities, can also pose challenging environmental problems.
