  present without compromising the ability of
  future generations to meet their needs.

What is an Ecological footprint
The Ecological Footprint measures the amount of
nature's resources an individual, a community, or
a country consumes in a given year.

What is an Ecological footprint
It takes into account the land required to supply
the resources we consume such as food timber and
energy, the land we live on and the land taken to
absorb our impacts such as pollution and waste.

How much is there for each Global Citizen
? There are 12.4 billion hectares of
bio-productive land on Earth. The world
population is approximately 6,000,000,000. For
each person there is 0.25 hectares of arable
land, 0.6 hectares of pasture, 0.6 hectares of
Forest and 0.03 hectares of built up land 1.5
hectares per capita. If we include seas there
exists 2 hectares per capita for human use. (EACH
!)

• HOWEVER some of this space is used by 30,000,000
  other species that share this planet. In order to
  protect these species it is estimated that 12 of
  the earths ecological capacity needs to be
  reserved for them if they are to survive.
• If we allow land to protect these species it
  means that only 1.7 hectares per capita are
  available for human use.

1.7 hectares the ECOLOGICAL BENCHMARK for
comparing peoples ecological footprints. Assuming
NO further environmental damage the amount of
available biologically productive space will drop
to 1 hectare per capita when the worlds
population reaches 10,000,000,000.

• The 'ecological footprint' of industrialized
  countries (resources consumed per person) is
  huge 4-6 hectares of land are needed to maintain
  the average consumer lifestyle in the North. Yet
  in 1990 the total available productive land
  globally was only 1.7 hectares per person.

How to Reduce an Ecological Footprint ?

• Reducing waste of energy
• Reducing the amount of water we use.
• Changing our diet so we use less land
• Making our houses more eco-friendly
• Reducing our reliance on transport
• Reducing pollution we create
• Reducing waste we generate
• Encourage people to recycle
• Protecting plants and animals
