Title: ECOLOGICAL FOOTPRINT
1ECOLOGICAL FOOTPRINT
2What is an Ecological Footprint?
- If you had to provide everything you use from
your own land how much land area would you
need? This land would have to provide you with
all of your food, water, energy and everything
else that you use. The amount of land you would
need to support your lifestyle is called your
Ecological Footprint. The ecological footprint is
one way of measuring the impact a person has on
the environment.
3Is the World Big Enough for All of Our BIG feet?
- The size of a persons Ecological Footprint will
depend on many factors. Do you grow your own
food? Do you walk or drive? Do you use renewable
or non-renewable energy sources? Everyone has an
ecological footprint because we all need to use
the earths resources to survive. But we must
make sure we dont take more resources than the
earth can provide.
4Different people in the same country will have
different sized ecological footprints. Different
countries also have different ecological
footprints.

5How would factors such as population density,
electricity use, and oil consumption affect the
size of a persons ecological footprint?
