Chapter 1: Natural Resources and Their Use

A renewable resource can become non-renewable when humans use it faster than Nature can restore or regenerate it. For example, if forests are cut down faster than they can grow back, or if groundwater is extracted faster than rainfall can replenish it, these resources effectively become non-renewable. Actions to prevent this include:

• (i) harvesting timber only up to the rate at which forests can regenerate;
• (ii) practising water conservation and traditional water harvesting to maintain groundwater levels;
• (iii) avoiding over-fishing by respecting spawning seasons; and
• (iv) reducing pollution in rivers and water bodies so that Nature's cycles of restoration are not disturbed.

Five ecosystem functions that serve humans (also called ecosystem services) are:

• (i) Oxygen production – trees and plants naturally release oxygen that all living beings need to breathe;
• (ii) Water filtration – forests and wetlands naturally filter and purify water, providing us with cleaner water;
• (iii) Soil formation and fertility – decomposition of organic matter by bacteria, fungi, and insects enriches the soil, making agriculture possible;
• (iv) Pollination – bees, butterflies, and other insects pollinate crops, enabling food production; and
• (v) Prevention of soil erosion – the root systems of trees and plants hold soil together, protecting farmland and preventing floods.

Renewable resources are natural resources that can be replenished or regenerated naturally over time if used sustainably. Examples include sunlight, wind, water, forests, and soil. Non-renewable resources, on the other hand, are formed over millions of years and cannot be replenished at the rate at which we use them — examples include coal, petroleum, and metal ores.

Key differences:

• Renewable resources restore themselves naturally; non-renewable ones do not.
• Non-renewable resources will eventually run out if consumed continuously; renewable ones will last indefinitely if managed responsibly.

What people can do to protect renewable resources:

1. For forests: Harvest timber only at the rate forests can regenerate; plant native trees to restore cleared areas; avoid forest fires caused by negligence.
2. For water: Practise traditional water harvesting methods, reduce wasteful consumption, process and reuse wastewater, and rejuvenate ponds and tanks to maintain groundwater levels.

By respecting Nature's rhythm of restoration and regeneration, we ensure these resources remain available for future generations.

Many traditional cultural practices reflect a deep respect for Nature and mindful use of resources. At home, practices like offering water (arghyam) to the sun, performing Tulasī pūjā, and treating rivers as sacred discourage wasteful or disrespectful use of natural resources. In agriculture, communities traditionally refrained from fishing during spawning seasons, used cow dung as natural fertiliser, and practised multi-cropping — all of which support Nature's regenerative cycles. Sacred groves in many regions were protected from any cutting, preserving biodiversity and water sources. These practices reflect the understanding that humans are stewards of Nature, not just its consumers.

When producing goods for current use, several important considerations must be kept in mind. First, pollution control is essential — industries should minimise waste discharge into rivers and air, as seen in guidelines for cement factories by the Central Pollution Control Board. Second, production should aim to use sustainable or alternative materials — for example, replacing cement with traditional mud, stone, or recycled waste materials where possible. Third, the fair distribution of resources and benefits must be ensured, so that vulnerable communities are not deprived of clean air or water due to industrial activity. Finally, production processes should be designed to support local employment and be sensitive to the climate and geography of the region, combining traditional knowledge with modern technology.
