very clearly, this is down to deforestation. this is because so much land has been cleared, so much license has been given to forests to create agricultural land that, in fact, that's dried the ground out, kept less moisture in it, and made it more susceptible to fires if they occur. and others say, too, fires are the first step in deforestation, burn the land, clear it, put cattle on it, make your money and your sell your beef. there's a process happening that could permanently damage the ecosystem of the amazon. we all depend on it for our oxygen. is it reaching a tipping point where the damage caused becomes irrevocable and causes a self-fulfilling cycle of fires every year. >> thank you so much for being there and showing us what's going on. the news continues now so i'll hand it over to chris for
