So what's this carbon footprint thing all about...

So what's this carbon footprint thing all about?

Is it about carbon emmissions? Is there anything more profoundly simple to say on the subject?

So lets plant a few trees - will that help? Come on world!

In the developed world the average[1] persons carbon dioxide emissions are almost 10 metric tonnes per year. This is called their carbon footprint and comes mainly from their household energy usage and transport requirements car travel, flights and commuter transport. Carbon dioxide is a greenhouse gas which, when released into the atmosphere, acts like a thickening blanket, trapping the sun's heat. Too much carbon dioxide in the atmosphere is causing the planet to warm up. To help prevent global warming, we all need to reduce our emissions and look at ways we can mitigate the emissions left over that we are responsible for. Trees are a natural green machine which absorb carbon from the atmosphere and release it as oxygen. To this end, trees are an effective way of absorbing the carbon you release into the atmosphere.

So lets get planting now!

A New Zealand -led group of scientists seeking to find the cause of earthquakes by investigating South Island faultline...

Read below:

A New Zealand-led group of scientists wants to find out more about the South Island's most dangerous fault line and gain more of an insight into what causes earthquakes.

The alpine fault, which runs 650km along the spine of the South Island between Milford Sound and Marlborough, ruptures every 200 to 400 years producing an earthquake of about magnitude eight. Its last episode was 291 years ago.

Project leader Dr John Townend says the scientists will drill several kilometres into the fault in the Mt Cook National Park region. They will examine physical and chemical changes taking place inside the fault to find out whether pressure is building towards another rupture.

Dr Townend says it is an ambitious and technically challenging mission and will be the first time that anything on such a scale has been attempted in New Zealand.

Scientists have been awarded $US44,500 to hold a five day workshop in the South Island early next year to plan the project. Up to 50 researchers will attend the event, many coming from overseas.
