The consequence of deforestation has effects in biodiversity, when a forest has been deforestated the ground lose nutrients, water and propriety’s, so we interrupt the cycle of life of a lot of different species of plants and animals, in fact we destroy the biodiversity of the ecosystem.
Then if we have less trees we’ll have more carbone dioxide (CO2) in our atmosphere. So we start a vicious cycle of destruction including the climatic changes.
The best option for help the planet to avoid the consequence is the reforestation and help the ground with manage programs of ground to give it nutrients again.
