siniylev [52]

Deforestation is the progressive decrease of the forest as a consequence of human activities. This practice (deforestation) irreversibly alters the ecosystem and has adverse effects on human health.

Deforestation is the progressive decrease of the forest regions in order to use deforested lands with diverse purposes (e.g., agriculture, urbanization, etc).

In the short-medium term, deforestation may lead to many negative outcomes associated with the loss of biodiversity.

Moreover, it is well known that trees release oxygen and consume carbon dioxide during photosynthesis.

In consequence, in the long term, deforestation may cause climate change (e.g., desertification, soil erosion, flooding, etc.), which is associated with an increased amount of greenhouse gases in the atmosphere.
