Tropical forests are present in several regions of the planet, concentrated in areas near the equator. In addition to being extremely rich in biodiversity, these forests also function as large carbon warehouses stored in plant tissues. The Amazon is the most extensive tropical rainforest, representing about a third of them. The Congo basin in Africa is second, and the forest of Southeast Asia is third. These three exert a significant influence on the rainfall regime observed on continents, as they help regulate the global climate at different scales.

For example, in the case of the Amazon, the rainforest releases freshness and moisture into the atmosphere through evapotranspiration, affecting the Prata basin, which includes Argentina and Uruguay.

There is a delicate and complex connecting network that unites various regions of the planet; it is worthwhile to highlight the relationship of the Amazon to the Sahara desert: a cloud of dust comes from there, crosses the Atlantic Ocean and lands in the forest, fertilizing the soil – thanks to the presence of nutrients such as phosphorus – and helping the formation of clouds.
