"In the year to August 2004, more than 26,000 square kilometres (10,000 square miles) of forest were chopped down, an area larger than the American state of New Jersey.
The area deforested in the past year was up 6% on 2003, far worse than the Brazilian government’s predictions that it would rise by no more than about 2%. It was the second worst year for the destruction of the rainforest since satellite surveys began (see chart). It is reckoned that almost a fifth of the Brazilian part of the forest has now been wiped out; if it were to continue at this rate, it would all be flattened within the next two centuries."
"The world’s greatest stores of biodiversity—and some of its main suppliers of the oxygen we breathe—are still being chewed up at an alarming rate, despite decades of talk among world leaders and environmentalists about the need to preserve them." http://www.economist.com/agenda/displayStory.cfm?story_id=3996152
