In Text Questions

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


(i) Plant trees and support reforestation efforts.
(ii) Recycle the materials for reducing the burden.
(iii) Reuse of materials such as plastic, cans, envelopes, papers, bags, polythene packets, etc.
(iv) Turn off lights and appliances when you’re not using them, and use energy-efficient products.
(v) Look for cleaning products that are made with natural ingredients.

2. What would be the advantages of exploiting resources with short-term aims?


The advantages of exploiting resources with short-term aims are as follows:
(i) We will be able to fulfil the requirement of mass population.
(ii) We will be able to achieve industrial growth and thus more economic development.

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


Using a long-term perspective in managing resources can help to ensure the sustainability of resources.
The natural resources will last for generations to come and will not merely be exploited to hit short-term gains. Also, it can lead to more stable and predictable resource management practices.

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


There must be equitable distribution of resources because only the selected people can exploit the resources and use it. While the people who are unable to afford it cannot use the resources. There are only a handful of rich and powerful industrialists, who see these resources as a means to reap huge profits. They are the main threat to equitable distribution of our resources.

1. Why should we conserve forest and wildlife?


Forests are biodiversity hot spots. There measure is by number of species found in an area. Conserving these habitats helps to preserve biodiversity and the unique ecosystems that support it. Forests play a critical role in regulating the Earth’s climate. They absorb carbon dioxide from the atmosphere.

2. Suggest some approaches towards the conservation of forests.


(a) Forests must be used properly in order to make use of forest products and giving ample/enough time for them to restore.
(b) Local community must be made aware of the consequences of loss of forests and they must be the part of management of the forests.

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


  • Tankas in Rajasthan
  • Ahars and Pynes in Bihar
  • Kunds in Maharashtra
  • Bawdis in Gujarat
  • Bundhis is Madhya Pradesh
  • Kulhs in Himachal Pradesh

2. Compare the above system with the probable system in hilly mountainous areas or plains or plateau regions.


Traditionally, water harvesting is performed by local canal irrigation systems known as kulhs in hilly areas like Himachal Pradesh. The water from streams is diverted into man-made channels that distribute it to various villages. The water in these kulhs is managed by a common agreement between all villages that share it. It also seeps into the soil and helps raise the water table.

3. Find out the source of water in your region/locality. Is water from this source available to all people?


Water supply by the municipal government is the primary source of water in most towns and cities. The residents of houses with a water supply are able to access this facility, but many others do not. For their daily consumption, they have to wait in long lines at the nearest municipal water tap.


1. What changes would you suggest in your home in order to be environment-friendly?


(i) Check the wastage of water, close the taps properly, recycle the water of wasting machine into toilets.
(ii) Stop the use of bulbs and switch over to CFL lights.
(iii) Use solar water heater and cookers, install solar cell panel for electricity.
(iv) Reduce the garbage by not throwing such items which can be reused and recycled.
(v) Turning off the engine of the car when stopped at a red light.
(vi) Walking or bicycling to nearby places rather than using a motorised vehicle.

2. Can you suggest some changes in your school which would make it environment-friendly?


(i) Ask the students to use bicycles or come to school on foot.
(ii) Ask students to switch of the fans and light when not in use.
(iii) To use the waste water in garden for watering the plants.
(iv) By implementing a rainwater harvesting system
(v) By conserving energy and avoiding unmindful use of all natural resources

3. We saw in this chapter that there are four main stakeholders when it comes to forests and wildlife. Which among these should have the authority to decide the management of forest produce? Why do you think so?


Forests can be managed and conserved in the best way possible when joint forest management committees (JFM) are formed by representatives of the Forest Department and local people. For centuries, the local people have been using the forests and have developed practices that not only benefit them, but also benefit the forest and the wildlife within those forests. A long-term conservation effort can be achieved through the wisdom of the local people.

4. How can you as an individual contribute or make a difference to the management of (a) forests and wildlife (b) water resources and (c) coal and petroleum?

(b) Water Resources: We should stop wasting water in our day- to-day lives and cultivate water-saving habits.
(c) Coal and Petroleum: By practicing the three Rs, saving all forms of energy, using fluorescent lighting, turning off unnecessary electronic devices, walking instead of driving, and using stairs instead of lifts, we can conserve coal and petroleum.

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