In many localities it is customary to heap and burn fallen leaves on the spot. Give an environmental assessment of these actions.

When vegetation is burned, smoke is emitted into the air, which includes dust, carbon monoxide, nitrogen oxides and a number of carcinogenic compounds, as well as dioxins – one of the most toxic substances for humans. To prevent the fallen leaves from acidifying the soil, it is better to dispose of the fallen leaves for the benefit of the environment, namely, compost.
