Solution

Burning the dry leaves destroys the essential nutrients which can be restored to the soil and also causes air pollution by the release of smoke.
Composting the dry leaves along with the other biodegradable substances, recycles the nutrients present in the leaves and restore them in the soil.
In this way, the soil becomes more fertile. Hence, it would be a wise option to dispose off the dry leaves by composting them.
