There are massive free planting programs in the east. Over a billion planted in Pakistan and huge military type operations in China. I don't know if it will make up for tropical deforestation but we have to try. We also need to reforest parts of the UK and Europe to help to prevent flooding and make a start on offsetting CO2 emmisions. Algae and lichen are also massive CO2 absorbers which need to be explored. Of course all this time we need to start reducing the use of fossil fuels and, as I see it, getting rid of private transport would be a huge help.

As a tecnophile I am hopeful of a technical solution being found. Whether that is safe nuclear power, hydrogen based or something entirely different is beyond my ken! All in all though, I am optimistic. Maybe falsely but at least it stops me getting depressed :-)
