The amount of mysteries all around the world is numerous, but when we are talking about amazon then it must be special, a huge forest where anything can be hidden there and exploration will never be as easy an option for anyone no matter the technology they have since nature will always have the upper hand.
Knowing that there is a high possibility that they are hiding something there and not allowing any information to be distributed makes the situation kinda strange especially that you have mentioned that there are lands full of gold which would make a goal for every powerful government to put its hand on, but I wonder if they find it, or yet still exploring the huge lands and maybe fighting and killing creatures there in order to achieve their greedy purposes.
Nice read, so informative!
I think that a massive exploitation could generate a war, because there are mutual interests, not only of local governments, but also other nations and especially the world elite, which are behind many mysteries around the globe. Furthermore, we cannot fight the elite, they are powerful.
