Forests of Brasil Declining or not?

I 'm an old guy and have been extremely worried hearing about the decline of the rain forest! last year I was in Brasil. In 2 weeks I flew from Sou Paulo To Tocantins then to, Matto Grosso, the Amazon!Then back to SP. Drove from Campinas to Sorrocaba and then to Bella Horizonte! The whole country is a huge Forest! Every village and town had herbal remedies from local trees, there was just an overwhelming abundance of forest and useful trees everywhere! So why the Hype when 9/10th of Brasil are forests!
