Management of Natural Resources

Textual Questions and Answers

1. What changes can you make in your habits to become more environment friendly?

Answer: We can make the following changes in our habits to become more environment friendly:

(i) Avoid wastage of water and use water carefully.

(ii) Switch off unnecessary lights and fans when not in use.

(iii) Do not waste food and take only as much as required.

(iv) Walk or use a bicycle for going to nearby places instead of using vehicles.

(v) Separate wastes into recyclable and non-recyclable categories.

(vi) Reuse carry bags, packing materials, plastic containers and other reusable materials.

2. What would be the advantage of exploiting resources with short term – aims?

Answer: The exploitation of resources with short-term aims means the consumption of resources in such a way that they can help in achieving the short term goals without the concern for future generations.

The advantages of exploiting resources with short term aims will be:

(a) Industrial growth will be fast.

(b) The percentage of gains will be much higher in comparison to long term aims.

(c) Capital rotation will be faster.

(d) It will lead to rapid agricultural development.

3. How would these advantages differ from the advantages of using a long-term perspective in managing our resources?

Answer: If the resources are used with long term perspective:

(i) The demand of present as well as the future generations will be met.

(ii) There will be a lower level of pollution.

(iii) If the resources are used in the long run, there might be enough time for the resources to get replenished. In such a situation, no generation would be deprived of resources.

4. Why do you think there should be equitable distribution of resources? What forces would be working against an equitable distribution of our resources?

Answer: Equitable distribution of resources is when every individual gets an equal right to access all the available resources and is benefited, directly or indirectly. Equitable distribution of resources is necessary as we all human beings, whether rich or poor have got equal rights on the usage of the resources. It also avoids the division of society to an extent.

The main forces which work against equitable distribution of resources include:

(i) Lack of natural resources.

(ii) Excessive consumption by the rich.

(iii) Profit motto by people exploiting resources.

(iv) Corruption, etc.

5. Why should be conserve forests and wild life?

Answer: It sustains life on the planet, provides clean air and shelter. Also, forests help conserve biodiversity. Forests provide many resources such as food, medicine, fabric, and raw materials.

The conservation of wildlife is necessary for prevention of drought, new deserts, fires as well as flood. Also, this conservation ensures that the upcoming generations of human and wildlife will be surrounded by nature thereby loving it and understanding the significance of wildlife.

6. Suggest some approaches towards the conservation of forests.

Answer: Some approaches towards the conservation of forests are as follows:

(a) People should show their participation in saving the forest by protesting against the cutting of trees. For example, Chipko Andolan

(b) Planting of trees should be increased. Rate of afforestation must be more than that of deforestation.

(c) Some people cut precious trees such as Chandan to earn money. Government should take legal steps to catch these wood smugglers.

(d) Habitants of forests must not be bothered by the forest officials. Otherwise, this would result in the clash between tribal people and the government officials, thereby enhancing the naxal activities in forests.

7. Find out about the traditional systems of water harvesting / management in your region.

Answer. The traditional system of water harvesting in our region is the rooftop water harvesting using tanks. Tanks are kept at the roofs during rains. The rainwater gets collected in these tanks, and this rainwater can be used later for various household chores.

8. Compare the above systems with the probable systems in hilly/mountainous areas or plains mor plateau regions.

Answer: Dams are built over rivers in hilly/mountainous areas. They are more advantageous because to store running river water which can be used to generate electricity. Moreover, since the water stored in dam keeps flowing to turn the turbines, it does not act as a breeding ground for mosquitoes which spread malaria. The stagnant water in ponds and cakes, however, becomes a breeding ground for mosquitoes.

9. Find out the source of water in your region/locality is water from this source available to all people living in that area?

Answer: The source of water in our region is ground water. Water from the source is available to all the people living in that area.

Answer: There are the two non-renewable resources that are used by every individual in form of fuel either for cooking or an automobile, in factories, in railways and so on.

5. What can you as an individual do to reduce your consumption of the various natural resources?

Answer: Water, forests, coal, and petroleum, among other natural resources, are critical for human survival.

The following are some of the ways we can limit our use of various natural resources:

1. Deforestation should be avoided.

2. To limit the amount of trees cut down, we should utilise recycled paper.

3. We should not dispose of wastewater.

4. Rainwater harvesting should be practised.

5. To reduce the amount of petroleum we consume, we should carpool.

Alternative energy sources, such as hydropower and solar power, should be used.

6. List five things you have done over the last one week to:

(a) Conserve our natural resources.

Answer: The five things done by me over the last one week conserve our natural resources were:

(i) Travel by a CNG bus for long distances and walk for short distances.

(ii) Use recycled paper.

(iii) Throw biodegradable and non-biodegradable waste into separate bins.

(iv) Plant trees.

(v) Harvest rainwater.

(b) Increase the pressure on our natural resources.

Answer: To increase the pressure on our natural resources:

(i) Use non-renewable resources of energy.

(ii) Waste water.

(iii) Waste electricity.

(iv) Use plastics and polythene bags for carrying goods.

(v) Use escalators.

7. On the basis of the issues raised in this chapter, what changes would you incorporate in your life-style in a move towards a sustainable use of our resources?

Answer: One should make several changes in daily life to move towards the sustainable use of our resources. We should stop cutting trees and instead practice tree plantation. The use of plastic and polythene bags for carrying goods should be avoided, and recycled paper should be used whenever possible. Biodegradable and non-biodegradable wastes should be thrown into separate bins. We should use minimum water and repair leaking taps to prevent wastage of water, and rainwater harvesting should be practiced.

Vehicles should be avoided for short distances and instead we should walk or use a bicycle. For long distances, public transport like buses should be preferred instead of personal vehicles. Electrical appliances should be switched off when not in use, and fluorescent tubes should be used instead of bulbs to save electricity. We should use stairs instead of lifts whenever possible. During winter season, wearing an extra sweater can help reduce the use of heaters and save energy.
