Management of natural resources class 10 ncert MCQ & SAQ

Management of natural resources class 10 ncert solution:

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

We can be eco-friendly by:

→ Using the principle of 3R's i.e. Reduce, Reuse and Recycle.

→ Putting off unnecessary lights and fans.

→ Using unleaded petrol in vehicles.

→ Using local transport like buses or trains.

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

If resources are exploited with short-term aims it will be very beneficial for the present generation as it will help in the growth of the economy at a faster rate.

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

If resources are used in accordance with short term aims, the present generation will be able to utilize the resources properly for growth and development.

But if we use resources with long term aims, future generations will also be able to utilize resources for fulfilling their needs.

Thus it would be better to use our natural resources with a long term perspective so that it could be used by the present generation as well as conserved for future use. But it will deprive future generations from the benefits of these resources as resources are exhausted.

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

Natural resources of the Earth must be distributed among the people uniformly so that each and every one gets his share of the resource.

Human greed, corruption, and the lobby of the rich and powerful are the forces working against an equitable distribution of resources.

1. Why should we conserve forests and wildlife?

We should conserve forests and wildlife because they are essential for us in following terms:

→ Forests provide us oxygen, they cause rainfall.

→ Forest prevents soil erosion.

→ Plants are dependent on animals and birds for their pollination and seed dispersal.

→ Forests provide us with various medicines.

→ Various forest products are used as raw materials in industries.

2. Suggest some approaches towards the conservation of forests.

Some approaches towards the conservation of forests are:

→ Conversion of forests into national parks and sanctuaries.

→ Not to allow the destruction of forests for making roads, dams and hotels etc.

→ Planting of trees should be increased.

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

In plains, the water harvesting structures are crescent-shaped earthen embankments. These are low, straight, and concrete.

In hilly regions, the system of canal irrigation called Kulhs Is used for water harvesting. This involves a collection of rainwater in a stream, which is then diverted into man-made channels down the hillsides.

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

Management of natural resources class 10 n cert  long question

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

Answer: We should use the formula of three R’s in our home in order to be environment friendly.

1. 

   Reduce, i.e. to use less, and save the water and the electricity by stopping their wastage.

2. Recycle, i.e. to segregate the waste so that materials which can be recycled should be dumped in a place for recycling.

3. Reuse, i.e. to reuse certain materials like bottles Of jams and pickles for storing other kitchen items, etc.

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

Answer: There would be no advantage of exploiting resources with short-term aims. Their exploitation may appear to be advantageous in the short-term but it is highly disadvantageous in the long- term. By doing so, we may be able to enjoy the comforts Of life but we would damage our environment gradually.

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

Answer: The exploitation of natural resources with short-term aims are advantageous for present generation to meet their daily requirements whereas management of natural resources with long-term perspective are aimed to fulfill the needs of future generations and to maintain their sustainability.

Question 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: Everybody has equal rights over natural resources and also everybody should get the benefits from them. Therefore, equitable distribution of resources is essential to ensure that everybody gets their due benefit. But many forces go against the equitable distribution of natural resources. The geographical factors are the most important factors which do not allow equitable distribution of natural resources. Economy is another factor which prevents equitable distribution Of these resources
