(a) Leftover food can be collected and used to make compost. Compost provides nutrients essential for the growth and development of plants.
(b) We would prefer to eat food on a banana leaf plate. This is because a leaf plate is a harmless substance that can be used to make manure by the process of composting, whereas plastic plates cannot be converted into harmless substances by composting. They are not degradable so remain in the environment and create many problems.
Benefits of composting
- When compost is placed on top of existing soil, it adds nutrients, such as carbon and nitrogen. These nutrients are used by plants for growth and photosynthesis.
- Microorganisms, such as bacteria, fungi, and protozoa, decompose organic material. The presence of microorganisms is vital because they aerate the soil, which speeds up the composting process
- Composting keeps as much as 30% of waste from going to the trash can.
- Composting is free and a lot healthier for the environment.
