In my world, I would like to have a certain configuration and I wonder if it's plausible or not.
There is a continent with a climate similar to the Amazonian basin, covered by a very dense forest. This climate covers much of the continent. It is inhabited by natives tribal societies scattered around. The rest is made of different type of tropical and subtropical forests. I would like the continent to stay relatively unsettled.
The problem is that it's part of a bigger world. His close neighbour is a large continent with many civilizations. The most advanced of these countries have a level of advancement similar to 15th century Europe. These civilizations trade with other continents by the sea and some of the trading routes goes along the coast of the jungle continent. However, these people live in temperate climates and are not accustomed to the hot/humid weather. I guess they might establish some trading ports like the Europeans did when they began expansion in Africa, India and Asia but not much more.
- Considering that some areas on the east coast are drier. They could be easier to settle.
The area is somewhere between 1,5 to 2 million sq km.
The continent has many unique species not found anywhere else because it was separated form the other landmasses long ago. It's different but there is nothing that is considered more dangerous than our own Amazon.
Is it plausible that this continent is still mostly unsettled and still populated by hunter-gatherers?
