Explanation:

Slash - and - burn deforestation is often used to clear land for agricultural purposes. Farmers cut down trees (slash) and then burn the debris (burn) to create fertile soil for crops. Canals like the Panama Canal, office buildings, and National Parks are not the most common causes of slash - and - burn deforestation. Canals are for waterway construction, office buildings for urban development, and National Parks are meant to protect natural areas rather than cause deforestation.

agriculture
