Whilst browsing the internet, I came across two very nice websites that I really liked and I hope you like them too:
The first is the Breathing Earth Website : this is a real time simulation of the world's CO2 emissions and birth and death rates. Whilst it is only a simulation, it did make me think.
1 ha of trees removes approximately 3.5 tonnes of CO2 from the atmosphere per annum and you can measure your own Carbon Count Number here. CO2 is one of the main contributers to Global Warming and reducing its emmission will help to stem the damage caused by global warming.
The other nice and totally unrelated website which I came across was Wonderclub listing the "Wonders of the World" , with the wonders of the world listed under:
The Seven Wonders of the Ancient World
The Seven Wonders of the Medeival Mind
The Seven Natural Wonders of the World
The Seven Underwater Wonders of the World
The Seven Wonders of the Modern World
The Seven Forgotton Natural Wonders of the World
The Seven Forgotten Modern Wonders of the World
The Seven Forgotten Medeival Wonders of the Mind
The Forgotten Wonders of the World
This site brought home to me the number of places I need to travel to and see and how did we forget about all those other wonders?

Synthetic Trees
We know that carbon dioxide is one of the main contributers to global warming and that trees effeciently remove carbon dioxide from the atmosphere.
Dr. Klaus Lackner from Columbia University first announced an idea to build "synthetic trees" back in 2003. His original idea emenated from his Daughter's high school project and his proposal was to build synthetic trees which would remove carbon dioxide from the atmosphere.
At the time many scientists believed that the proposal was not practical and thought Dr Lackner's design wouold not hold together on the scale he proposed. They felt that you would expend more energy in capturing the CO2 - in keeping the slats coated in absorbent and disposing of it - than you would save.
Still working on the idea Dr. Lackner has now progressed his idea to large scale air capture technology and has successfully demonstrated a prototype which he expects to be commercialised in 2 to 4 years.

In the meanwhile trees are the best we've got for removing carbon from the atmosphere with 1 ha of trees removing approximately 3 tonnes of carbon from the atmosphere yearly.
