Question

A lot of dry leaves are collected in a school garden and are burnt every day. Do you think that it is right to do so? If not, what should be done to dispose off the dry leaves?

Answer 1

Biodegradable substances

• Biodegradable substances are substances that can be decomposed by the action of microorganisms after some time.
• These substances are generally natural substances or products made from natural substances.
• These substances do not harm the environment.

Composting

• Compost is a mixture of ingredients used to fertilize and improve the soil.
• Composting is the natural process of recycling organic matter, such as leaves and food scraps, into a valuable fertilizer that can enrich soil and plants.

Disposal of dry leaves

• Dry leaves are biodegradable as they can be easily decomposed by microorganisms.
• The burning of dry leaves causes air pollution as it releases carbon dioxide.
• The dry leaves should be composted so that they can act as manure.

Hence, the dry leaves should not be burnt instead they should be composted as that would not cause any pollution.
