all over the world, and the president's vision for boosting exports has delighted farmers like vanderley wegnerng ago. during our time in the amazon, we keep hearing that only brazil can decide what to do with the forest. but the trees store so much carbon that the more of them are cut down, the more we lose one of the very few things holding back to rise in global temperatures. so what happens here matters far beyond brazil. so my name is erika berenguer. i am a scientist, even though i don't wear a white coat. so i work in the amazon, this beautiful forest, and i am from brazil. erika is a researcher based at the university of oxford. she has studied the trees of the amazon for the past ten years and she has always loved them. for me, it is really important because the amazon cannot speak up, the trees can't speak up, they cannot say that they are worth it, and they have a value, they are really important. so i have made it as my life, i have made it to study them, understand them, understand the forest and be able to speak up about its importance. erika has got to know the forest very well.
