Even young rainforests can help save the climate
Original deforestation in tropical areas is usually to create pasture, which the climate is a heavy blow. Deforestation releases large amounts of carbon dioxide into the atmosphere, of course, these trees will not absorb it. But this is not the end. When the ranch was abandoned (usually in a few years), the trees began to grow again, the formation of secondary forest. These forests may not have a lot of trees and forests as rich in biodiversity, but they are still trying to adjust the climate plays an important role.
From the University of Connecticut Storrs located ecologist Robin Chazdon bring along Rio de Janeiro's International Institute for Sustainable Development ( "Science refrigerator" magazine has been introduced in August last year over the issue) as well as a 60-person research team for the first time in Latin America secondary forest area of 43 districts were estimated, and then create a model to estimate the carbon storage capacity. They found that secondary forests accounted for a large proportion: in 2008, 17% of the forests in the history of 20 years, and another 11% between 20 years and 60 years (Figure). The team today in the "scientific progress" magazine reported that their model shows that if all these forests continue to grow in the next 40 years, they can store 8.5 billion tons of carbon, Brazil alone accounted for 71%, which equivalent to the carbon emissions of all fossil fuels throughout Latin America and the Caribbean from 1993 to 2014. The results show that under the circumstances to stop cutting, secondary forests can be a huge help to achieve climate goals.
