As the UN Climate Change talks began today in Poznan, Poland, the Brazilian government unveiled a bold plan to cut deforestation in the Amazon 70% over the next 10 years.  Deforestation is frequently quoted as contributing 20% to global warming emissions worldwide - and the Amazon, often referred to as "the lungs of the world" represents a very important reserve of forest carbon.  This commitment is a positive sign, especially after environment minister and champion of the Amazon Maria da Silva resigned earlier this year after her efforts to stop deforestation through the government were repeatedly thwarted.  The proof is in the follow-through of course - which Tasso Azevedo of the Brazilian forestry service says is now possible due to a major new fund from foreign nations to help conserve the Amazon.  Go straight to the source at BBC News.
