The rainforest in Costa Rica provides not only beauty, biodiversity and happiness, but also food.
There are certain types of plants you may use to survive is you are ever lost in the rainforest (hope this never happens) but is nice to learn this kind of knowledge simply because it´s a legacy that indigenous cultures in Costa Rica give to the rest of us; the world.
We have this wrong idea that in the tropical rainforest you will find coconuts, bananas and pineapples here and there, this is absolutely false, such plants are domesticated plants, this means they are no longer able to survive in wilderness, because they have been modified by humans since millennia and by now they completely depend on the presence of humans, so if you find such plants that means there is a house close by.
