Waste materials of plants like oxygen, shedded leaves, gums, resins, natural rubber, etc. are useful for humans.

Oxygen:

• During the process of photosynthesis, plants use atmospheric carbon dioxide, sunlight and water and as a waste product, they release oxygen which is used by humans in respiration.

• Without oxygen, humans could never survive.

Shedded leaves:

• Time to time, when leaves fall off from the trees, these leaves are used in the formation of natural manures and used as organic manures.

• Though shedded leaves are waste products of plants, they are useful for humans.

Gums:

• Gums are the result of injury to the bark or stem of the plant or produced by the stem due to stress or heat.

• Gums are used as a thickening agent, emulsifying agent and stabilizer.

Resins:

• Resins are produced in special resin cells of the plants or are the result of injury to the plants.
