deflorestação diminuiu 50% na amazónia

Deforestation of Amazon 'halved'
Brazil's government has announced estimates suggesting that deforestation of the Amazon rainforest has fallen by 50% this year.
The government says it believes this is the result of new protection policies.
But environmental groups warn it is too soon to be sure there has been a long-term reversal in the destruction of the world's largest rainforest.
Environment Minister Marina da Silva said some 9,000 sq km (3,475 sq miles) of forest was felled in the last year.
This compares with more than 18,000 sq km (6,950 sq miles) in 2003 to 2004.
Ms Silva said she believed this fall was the result of not only greater government control but also because of more emphasis on sustainable development projects.
