Question

Define slash and burn cultivation. Do you think it is a major cause of

deforestation across the world?

Answer 1

Answer:

POLLUTION

Explanation:

YES, Although traditional practices generally contributed few greenhouse gases because of their scale, modern slash-and-burn techniques are a significant source of carbon dioxide emissions, especially when used to initiate permanent deforestation.

Answer 2

Answer:

Traditionally, the area was left fallow and reverted to a secondary forest of bush. Cultivation would then shift to a new plot. After about a decade the old site could be reused. By the early 21st century, however, cleared areas were typically maintained in a deforested state permanently, causing habitat fragmentation and biodiversity loss. Although traditional practices generally contributed few greenhouse gases because of their scale, modern slash-and-burn techniques are a significant source of carbon dioxide emissions, especially when used to initiate permanent deforestation. In Southeast Asia, slash-and-burn agriculture for oil palm cultivation has been a major source of annual air pollution from smoke. (See also shifting agriculture.)

Slash-and-burn may be defined as the large-scale deforestation of forests for agricultural use. Ashes from the trees help farmers by providing nutrients for the soil. In industrialized regions, including Europe and North America, the practice was abandoned with the introduction of market agriculture and land ownership.
