What are Ecological Footprints?
(Eco – of the earth; logical our understanding of it.)
An ecological footprint analyses and measures our impact on our earth. How our footprint affects our earth.
It measures the resources we use and the waste we create in order to do a certain things.
> What is a resource?
>What is a waste?
The big question is : Are they in balance? Do we use more trees than we plant?
How much nature do we use? How much nature do we have?
-> Do we cut down and use more trees than we grow?
At the Earth Summit at Rio in 1992:
‘Humanity uses over one third more resources and than what nature can regenerate.’
At the Earth Summit at Rio in 1992, the final message to the people of the world was: we the people of the world must to lessen our impact on the Earth. Five years later, we live in a world with more people, more consumption, more waste and more poverty, but with less biodiversity, less forest area, less available fresh water, less soil, and less ozone layer.
We all know we must reduce our impact. But first we must know our impact.
NASA's map of our human footprint
The Human Footprint is an analysis of our human influence across the globe. In this map, human impact is rated on a scale of 0 (minimum) to 100 (maximum).
A score of 1 indicates the least human influence. These maps were made by Columbia University and NASA scientists using geographic information systems to combine global land use and land cover maps with population data. Using these technologies, the collaborators chose four types of data to measure human influence: population density, land transformation, human access, and power infrastructure.
Footprints of my pencil
What is it made of? Where does that material come from? Which place on the earth? Which country? How does it come to me? Where did I buy it from?
I DO NOT KNOW is good!
Have a guess. Use Probably or Maybe.
Maybe made in India, may be from Gujarat etc
What Where on earth / Which country? / How is it made? / How is it transported?
What do I know and what don’t I know. How can I find out.
