R Shanthini 20 Aug 2010

But we replace our forests with cities highways amp golf courses

Emissions Reduction Option 1 Increase the use of carbon sinks (such as forests where 70 of all photosynthesis occurs)

Stop destroying forests and grow more trees


The forest cover is already too small to help reducing global warming

How long does it take to grow a tree like this


Emissions Reduction Option 2 Change to non-CO2 emitting energy sources

What are theyNuclear HydroRenewables (Geothermal Solar

Wave Tidal Wind Biomass and Biogas) Muscle Power


Energy from sustainably managed renewable sources

Ulf Bossel ndash October 2005

Emissions Reduction Option 3 Reduce Population


If you are in USA you will be lighting 185 bulbs each with 200 W power

If you are in China you will be lighting 3 bulbs each with 200 W power

CO2 emissions per capita has stronger links with GDP per capita than with population


Emissions Reduction Option 4 Carbon Capture amp Storage (CCS)

Controversial since permanent storage of CO2 underground is not guaranteed


Controversial since the impacts on marine ecosystem (very fragile) are not known


Discussion Point 7
