Sustainability is
the process of maintaining resources so they are not depleted or permanently damaged
the ability to use resources faster than they are renewed
they ability to save resources for years and years
the process of using resources for one's own benefit without regard for others

What does ecological footprint measure?
How quantity of natural resources humans need compared to the earth's capacity to provide those resources

How is ecological footprint measured?
In terms hectares of land required by each person in a selected area for food, water, transport, housing and waste management
In terms of number of years it would take before resources ran out
In terms of the average life expectancy of a nation

greenhouse gases
climate change
Which 2 greenhouse gases contribute the MOST to global warming of Earth?

The graph below shows CO2 emissions and temperatures from 1909 to 1949. What conclusion is best supported by the graph?
There is no relationship between carbon dioxide concentrations and temperatures
As carbon dioxide concentrations increase, temperatures increase
As carbon dioxide concentrations increase, temperatures decrease
As carbon dioxide concentrations decrease, temperatures increase
How is the greenhouse effect produced?
When solar energy trespasses the atmosphere.
When some energy is reflected back to earth.
