GEO 105 – Environmental Science
Over-Population
Over-population occurs when human population increases faster than the available natural
resources. This leads to food shortage, housing problems, pollution, pressure on land, water and
forests, and destruction of ecosystems.
Types of Environment
1. Geographical / Natural Environment – Includes land, water, air, plants, animals and natural
features.
2. Man-made / Human / Cultural Environment – Includes buildings, roads, industries, farms and
dams.
Aims of Environmental Science
1. To give students general understanding of environmental science.
2. To promote environmental awareness.
3. To summarize the main principles of environmental science.
4. To educate people about environmental issues locally and globally.
Main Goals of Environmental Science
1. To understand science.
2. To learn how the natural world works.
3. To understand how humans interact with the environment.
4. To find sustainable solutions to environmental problems.
Multidisciplinary Nature of Environmental Science
1. Contains different branches of knowledge.
2. Studies human interaction with the environment.
3. Combines physical, economic and social sciences.
4. Addresses modern environmental problems.
5. Examines every part of an organism’s environment.
6. Builds knowledge of nature and human dependence.
7. Finds sustainable solutions within limited resources.
8. Integrates life, physical and health sciences.
9. Combines biology, chemistry, physics, geography and social sciences.
Scope of Environmental Science
1. Conservation of ecosystems.
2. Conservation of biodiversity.
