Answer:
Fahrenheit 451 demonstrates the dangers of a society focused only on the immediate gratification of the present. This society has all but erased history. Its members derive meaningless pleasure from watching their "families" on futuristic televisions and don't engage in any meaningful conversations.
They aerate the soil, pollinate blossoms, and control insect and plant pests. Many insects, especially beetles, are scavengers, feeding on dead animals and fallen trees, thereby recycling nutrients back into the soil. As decomposers, insects help create top soil, the nutrient-rich layer of soil that helps plants grow.
