Learning Outcomes

On successful completion of this module students should be able to:

1. Discuss the factors influencing human population growth and control and the implications for food production, agricultural systems, energy consumption and production

2. Evaluate the global impact of human activity on ecosystems and on global biodiversity

3. Assess the impact of human activity on major natural systems; on soils, fresh-water and marine systems, atmosphere and climate

4. Discuss the nature of the interrelationships between the major environmental systems and the implications that this has for controlling the scale of human impacts upon them as population increases in size

Brief description

This module identifies and examines the major impacts of the human population on the environment. Emphasis will be placed on the impact that population growth has had, and in particular will potentially exert on the biota, water, soils and atmosphere and the interrelationships between these systems. The development of our understanding of the complex nature of environmental systems is examined with appraisal of how our increasing knowledge may influence human attitudes to, and future use of, environmental resources.


Global population: factors influencing population growth, predictions for population size and distribution during this century.
Food supply: factors influencing and limiting global food production (agricultural and fisheries), predictions for future production.
Energy: supply and demand, environmental impacts of fossil fuel use, predictions for fossil fuel availability. Alternative energy sources and the environmental implications of their use.
Landforms and soils: quarrying, open cast mining, construction and their impact on landforms. Soil degradation, causes and implications.
Water supply: impacts on the freshwater resource of a growing human population.
Biodiversity: species loss, contributing factors, methods for assessment. Deforestation, impacts on wetlands. Impacts on marine systems.
Atmosphere: Local, regional and global impacts on the atmosphere. Local air pollution; acid deposition; ozone depletion; climate change, interrelationships with other environmental issues and predictions for the future scale of these impacts.
