Ecological Footprint - what's that?

The Footprint is a measure of people's natural resource consumption compared with nature's ability to renew these resources. Both the Footprint and renewable resources (or bio capacity) are expressed in a common unit called a global hectare, where 1 gHa represents a biologically productive hectare with works average productivity.

In 2008, the Earth's total bio-capacity was 12.0 billion gHa, or 1.8 gHa per person, while humanity's Footprint was 18.2 billion gHa, or 2.7 gHa per person. This discrepancy means it would take 1.5 years for the Earth to fully regenerate the renewable resources that people use in one year (Living Planet Report, 2012). In essence, we are now utilizing and depleting our valuable capital resources.

Carbon footing is one of the components. 

A carbon footprint is the measure of the environmental impact of a particular individual or organization's lifestyle or operation, measured in units of carbon dioxide.

A carbon footprint is composed of two parts, a primary and secondary footprint. 

• The primary footprint is the sum of the direct carbon dioxide emissions of burning of fossil fuels, like domestic energy consumption by furnaces and waters heaters, and transportation, like automobiles and airplane travel. 
• The secondary footprint is the sum of indirect emissions associated with the manufacture and breakdown of all products, services and food an individual or business consumes.

So, it seams that everything we do, do have an environmental impact, our carbon footing.  But What WE CAN DO is to CHANGE those areas of our lifestyle

• minimise (reduce) as much as we can those that have an extreme footing (like driving), 
• be mindful (think, assess, learn) before action
• get educated about eco issues - it's not just a fad
• but dont preach, bore others or get people on the defensive about their own footing. Compliance needs patience. People wont wanna change unless they will benefit from it. Selfish, but that's self-preservation (ego/face) kicking in. Most of us are hard-wire through our genes, others are learned from parents, environment, society - esp people we observe when young. 
• grow a thicker skin. Never mind people telling you - that's not the way we do things here and snigger at your efforts. Change is never easy. Lead by example. No need to justify your actions. START A QUIET REVOLUTION.
