The document discusses ecological footprints and sustainability. It defines ecological footprint as measuring the resources and land needed to support an individual or group. There is currently only 1.7 hectares of biologically productive land available per person globally to sustain human needs and protect other species. However, industrialized countries like the US and UK have footprints of 4-6 hectares per person. The document suggests ways to reduce footprints like using less energy and transport, changing diets, and protecting natural resources.

4. 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.

5. 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 .

6. 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 !)

8. 1.7

9. 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.

20. Now its up to you !

22. Reducing waste of energy

23. Reducing the amount of water we use.

24. Changing our diet so we use less land

26. Take only Photographs Leave only Footprints Only keep memories

27. What will you do ?
