Question

Identify the examples of sustainable development.

• A. Planting several dissimilar and different types of plants on the same land over successive seasons using the crop rotation method
• B. Using chemical pesticides to prevent crop destruction
• C. Composting food waste to grow plants and enrich soil
• D. Planting ten saplings for every tree that is cut for developmental projects

Answer 1

Answer: (A), (C), (D)

Planting ten saplings for every tree that is cut for developmental projects

1. Crop rotation ensures that there is an increase in production of the agricultural sector while maintaing a nutrient-rich soil. When the same crop is planted, only a particular nutrient required for that plant is used. However, when different plants are planted, the nutrients required for each plant is used equally. The fertility of the soil remains intact. This is a sustainable development.

2. Using chemical pesticides for plants might appear to protect the crops from pests. However, they are poisonous for birds and animals. This cannot be considered a sustainable development.

3. Composting our food waste has a two-way benefit. It not only reduces the waste accumulation, but the compost that is created is also used for fertilising the soil. This contributes to a sustainable development.

4. Sometimes development projects require felling of trees. However, when ten saplings are planted for every plant that is cut, it leads to a sustainable development.
