The Need for Sustainable Management
Natural resources such as forests, wildlife, water, coal, and petroleum are finite. As the human population grows exponentially, the demand for these resources is increasing at an alarming rate. Sustainable management ensures that we use resources judiciously to meet current basic human needs while preserving them for future generations. It also ensures equitable distribution of resources and minimizes environmental damage during extraction and use.
The 5 R's to Save the Environment
- Refuse: Say no to things people offer that you don't need (e.g., single-use plastic bags).
- Reduce: Consume less. Switch off unnecessary lights and fans, repair leaky taps, and do not waste food.
- Reuse: Use things again and again. Instead of throwing away plastic bottles or jam jars, use them for storing items. This is actually better than recycling, as recycling requires energy.
- Repurpose: When a product can no longer be used for its original purpose, use it for something else (e.g., a broken cup as a small plant pot).
- Recycle: Collect plastic, paper, glass, and metal items to manufacture new things instead of extracting fresh raw materials.
Forests and Wildlife
Forests are "biodiversity hotspots." The primary aim of conservation is to try and preserve the biodiversity we have inherited, as loss of diversity may lead to a loss of ecological stability. The stakeholders in forest management include:
- The local people who live in or around forests and depend on forest produce for various aspects of their life.
- The Forest Department of the Government, which owns the land and controls resources.
- Industrialists who use forest produce (like timber, paper) but are not dependent on the forests in any one area.
- Wildlife and nature enthusiasts who want to conserve nature in its pristine form.
Movements like the Chipko Andolan in the Himalayas successfully demonstrated how local community participation is essential for forest conservation.
Water For All
Water is a basic necessity for all terrestrial forms of life. Despite large dams and canals being built to meet water needs, poor management and unequal distribution mean many regions still face scarcity. Large dams face criticism due to three main problems: social problems (they displace large numbers of peasants and tribals without adequate compensation), economic problems (they swallow huge amounts of public money without generating proportionate benefits), and environmental problems (they contribute to deforestation and the loss of biological diversity). Water harvesting (like traditional systems of khadins, tanks, and nadis) is a localized, eco-friendly alternative to recharge groundwater without disrupting the ecosystem.
Coal and Petroleum
Coal and petroleum are fossil fuels formed from the degradation of biomass millions of years ago. They are non-renewable and will eventually be exhausted (estimates suggest known petroleum reserves may last around 40 years, and coal around 200 years). When burnt, they produce carbon dioxide, water, oxides of nitrogen, and oxides of sulphur. Inadequate oxygen during burning produces deadly carbon monoxide. The massive release of carbon dioxide heavily contributes to global warming. Therefore, these resources need to be used extremely judiciously, pivoting towards public transport, energy-efficient appliances, and alternative energy sources.
