Real time wildfire mapping in the United States



Although we are all watching the current wildfires in California, a more serious situation is occurring in Alaska with thousands of hectares currently affected. 

The Geospatial Multi-Agency Co-ordination Group provides real time mapping of current wildfires throughout the United States.  Zoom onto the flame showing a wildfire for its perimeter and then click for full details of the size of the fire, exact location and the extent to which it has grown or shrunk over the past 24 hours and also details of how much has been contained.  With high temperatures and less rainfall this is the worst season for wildfires to date.

U.S. Ecological Deficit Day

Today is US Ecological Deficit Day...for those of you who know all about ecological footprints then you know that we in the developed world are all guilty of exceeding our personal one planet allowance.  Today is the day  when the US exceeds its national biocapacity and goes into the red (i.e. deficit). Each year it gets earlier and today is that point in the Nation's ecological footprint balance.  More information.  Should every country adopt an Ecological Deficit Day...you bet they should!

Trash is for Tossers: say NO to trash

‘Trash is for Tossers (say NO to trash)’ is the blog of  Lauren Singer who is trying to live a zero waste life in the heart of New York City.  She is sharing her journey towards this excellent goal, although I suspect it is going to be a tough one. She has one great quote ‘I really decided that I not only needed to claim to love the environment, but actually live like I love the environment’.  She also gives two really interesting and helpful definitions:

Waste …’a  point source, meaning it is discarded by its holder with intent of it going to landfill. Trash is anything a person plans to throw away or anything a person deems obsolete that is then discarded in a manner where it will not be intended for re-purposing or reuse even if it unknowingly will be at some point in the future. ‘

Zero Waste means that I do not produce any garbage. No sending anything to landfill, no throwing anything in a trash can, nothing. However, I do recycle and I do compost. 

Lauren is really on the right path here and I for one will be following her journey and learn from her experiences.

World Population Day


On the 11th July 1987 the global population reached 5 billion and to mark this important milestone the United Nations decided to designate this day each year as World Population Day.  On this day organizations around the world raise awareness of our growing population and the issues that surround a rapidly growing population.  But is also about celebrating our achievements as well as bringing to our attention the plight of groups of people around the world.  The theme this year is raising the awareness of vulnerable woman and children in emergencies.
