Define Deforestation and Afforestation.

Hint: Afforestation is in a formerly sterile climate, the planting of trees. The loss of trees and habitats for human habitation and use is deforestation. Afforestation has a positive environmental effect. Industrialization, globalization and urbanization are a product of deforestation.

Complete answer:
Deforestation: Deforestation refers to the decline of protected areas globally that are lost to other applications, such as croplands, urbanization, or mining operations. Since 1960, deforestation has been adversely impacting natural habitats, wildlife, and the environment significantly exacerbated by human activities. Causes of deforestation are agricultural expansion, wood extraction (e.g., logging or wood harvest for domestic fuel or charcoal), and infrastructure expansion such as road building and urbanization. Very commonly, in order to induce deforestation, several mechanisms operate concurrently or sequentially.
Deforestation can be prevented by: planting a tree, Using less paper, Recycle paper and cardboard, Use recycled products, Buy only sustainable wood products, by not buying products containing palm oil, by reducing meat consumption, by not burning firewood excessively.

Afforestation: Afforestation is the formation of a woodland or tree stand (forestation) in an area where no prior tree cover was located. Special devices, such as a tree planting bar, are often used to make it faster and simpler to plant seeds.
Various advantages of Afforestation are: Constant availability of forest products, avoiding soil erosion, stabilizing the environment, reversing global warming and climate change, enhancing air quality, improving watersheds, protecting biodiversity, providing jobs and economic opportunities.

Note: 30 percent of the forests on earth is covered by trees. It is estimated that no rainforests would remain within 100 years. Every second, one and a half acres of woodland are chopped down.
