Unit 1- Intro Flashcards
Environmental Science:
Pursuit of knowledge about workings of the environment and our interactions with it
Environmentalism:
Social movement dedicated to protecting the natural world from undesirable changes brought by human choices
Environment:
Sum total of our surroundings, including all biotic and abiotic components
Environmental Geography:
Study of interrelationships between human and biophysical systems across a variety of spatial and temporal scales
Ecological Footprint:
• Tool used to express environmental impact of an individual or population
• Calculated in terms of area of land and water required to provide materials that a person or population consumes, and to absorb or recycle the wastes produced
Inverse of carrying capacity- measure of land and water required to sustain an individual, rather than the number of individuals that can be sustained by an area of land or water
Biocapacity:
• Capacity of a terrestrial or aquatic system to be biologically productive and to absorb waste
When a population exceeds or overshoots the carrying capacity or biocapacity of a system, the system will be at risk of permanent damage
Manipulative Experiment:
Researcher manipulates the independent variable
Natural Experiments:
• Can’t directly manipulate behaviour, but nature has already done that for us
• Interpret results from nature
i.e. compare closely related species to study evolution
Paradigm Shifts:
Abandoning a dominant theory due to new evidence in favour of a new one
Globalization:
Increasing global interconnectedness in train, politics, and movement of people
Cornucopian View:
Belief that people will find ways to make Earth’s natural resources meet all our need indefinitely
Cassandras View:
Belief that the world will be subjected to doom and disaster due to human impact on the environment
Cycles:
Shapes landscapes around us and guide flow of key chemical elements and compounds that support life and regulate climate
Resource Management:
Strategic decision making and planning aimed at balancing use of a resource with its protection and preservation
Stock:
• Harvestable portion of the resource
If stock is being harvested or withdrawn at a faster rate than it can be replenished then the stock will eventually be depleted
