I'm from Peru, not the Amazon, but the coast. Recently I made a presentation about Loreto. Loreto is a department from the Peruvian rainforest.
I'll provide you with some information in Spanish/English that I hope you'll find useful to start writing your essay.
Weather conditions:
In Loreto the climate is warm and rainy, with an average annual minimum temperature of 20°C and a maximum of 32°C.
Ubication:
Loreto limits to the north with Ecuador and Colombia, to the east with Brazil, to the south with the department of Ucayali and to the west with the departments of San Martín and Amazonas. The department of Loreto, whose capital is the city of Iquitos, is made up of 8 provinces and 53 districts.
The Loreto department can be reached by moving by plane, small plane and/or by boat. Loreto cannot be reached by land, because to date there is no route where a car, bus and/or motorcycle can travel. And the only way to get there is by air and river.
