Newly published research shows that the Amazon rainforest is being destroyed at double the rate of all previous estimates. The research was published today in the journal Science. A new analysis of satellite images of the Brazilian part of the Amazon basin shows that on average 6,000 square miles of forest is being cut down by selective logging each year. This is in addition to a similar amount clear-cut annually for cattle grazing or farming. As a result, up to 25% more carbon dioxide is released into the atmosphere every year.
