Define the ecological footprint
The theoretical measurement of the amount of land and water a population requires to produce the resources it consumes and to absorb its waste under prevailing technology.
Define the difference between an ecological creditor and debtor
Both calculated by the ratio of biocapacity to ecological footprint of consumption for that country.
Ecological Creditor- A country with a biocapacity that exceeds their ecological footprint of consumption.
Ecological Debtor- A country with an ecological footprint that exceeds their biocapacity.
What is a global trend for countries in ecological debt?
Most high income countries- as most people tend to be wealthier, they would have a higher quality of life and therefor use more resources.
Describe the global trends of biocapacity
The areas with a higher bio capacity includes South America, Russia and the US. This could be due to the resources they are able to provide as well as the size of the areas tend to be dependent on the biocapcity.
Define a carbon footprint
The amount of carbon dioxide released into the atmosphere as a result of the activities of a particular individual, organization, or community. Mainly produced by the burning of fossil fuels and is expressed as a weight of CO2 emissions produced in tonnes.
Define a global hectare
