What is the average
Canadian Ecological Footprint?
The maximum population size that can be regularly
sustained by an environment
What is Carrying Capacity?
The area of land required to provide the resources
consumed by an individual, city or nation.
What is Ecological Footprint?
Society's demand on nature is in balance with nature's capacity to meet that demand.
What is Sustainability?
Transportation, shelter, food, waste and water use
What are the elements of Ecological Footprint?
CO2, CH4, O3 and N2O
What are Greenhouse Gases?
Source of radiation (heat).
What is the Sun?
It is caused by humans activities emitting too much
greenhouse gases
What is Enhanced Greenhouse
Effect?
The unit describing the concentration of CO2 in the
atmosphere.
What is Parts per Million per Volume
(ppmv)?
Long wave radiation that is reflected from Earth into the
atmosphere.
What is infrared radiation?
Green plants absorb CO2 from the atmosphere and use it to
manufacture plant fibres, starches and sugars
What is photosynthesis?
People, bacteria, plants and fungi.
What are sources of carbon dioxide?
The amount of carbon in the Earth’s atmosphere.
What is trace?
Many people incorrectly believe it is only caused by
humans.
What is Global Warming?
Most atmospheric pollution (e.g., CO2, CH4, hydrocarbons) stays within this layer of the
atmosphere
What is the troposphere?
A reservoir that absorbs or takes up released carbon
from other parts of the carbon cycle
What is a Carbon Sink?
A reservoir that absorbs or takes up released carbon
from other parts of the carbon cycle
What is Carbon Fixation?
Oil, coal and natural gas that originates from decayed
plants and animals.
What is a Fossil Fuel?
A resource that can be used continuously without being
completely depleted because it regenerates itself
What is a Renewable Resource?
A human intervention to reduce the sources or enhance the sinks of greenhouse gases
What is Mitigation?
The process of change tobetter conform with
environmental conditions or other external stimuli.
What is adaptation?
The average household water consumption by one
person in Canada each day?
What is 300 L?
A financial or economic incentive to get emission
to the lowest possible level to make money.
What is Carbon Trading?
The percentage of Canada’s population living in the Great Lakes Basin?
What is 25%?
The Earth’s temperature without the Greenhouse
Effect
What is -18OC
