Reforestation could cut carbon levels by two-thirds, study says

Scientists say massive reforestation could capture two-thirds of manmade carbon emissions and reduce overall levels in the atmosphere to their lowest in almost a century. [AFP]

Good news: we can help halt climate change through a massive campaign of reforestation, according to a new study published Thursday.

Bad news: it would require covering an area the size of the United States in new trees, and even then some scientists are skeptical about the paper's conclusions.
