Which of the following practices does not contribute to intensive depletion of forest resources in West Africa?

Regrowing of forest trees does not contribute to intensive depletion of forest resources in West Africa. In fact, it is one of the ways to ensure the sustainability of forest resources. When forests are cleared for timber or other purposes, it is important to engage in reforestation efforts by planting new trees to replace the ones that were harvested. This ensures that there is a continuous supply of forest resources without depleting the existing ones. The other options listed such as the use of powerful tools for felling trees, clearance of forests for cash crops, and the use of fire or hunting in forests can all lead to the depletion of forest resources.
