Management of Natural Resources 
 
Why do we need to use our resources carefully? 
 
Q & A 
 
Q1: What is coliform bacteria? What does its presence in water indicate? 
 
Answer: Coliform is a group of bacteria which is found in human intestines. Its presence in water 
indicates contamination by disease-causing microbes. Its high presence in rivers and ponds elevates 
the risks of water borne diseases like gastroenteritis. 
 
Q2: State two reasons of launching "Ganga Action Plan". Which bacteria was found in Ganga 
water indicating contamination? 
 
 
 
Answer: The 'Ganga Action Plan', a multi-crore project was launched to clean river Ganga for the 
following reasons: 
1. the quality of the water in the Ganga was very poor,  
2. alarming increase of disease causing microbes in the river  
3. pollution due to dumping of untreated sewage and industrial waste.  
Fecal Coliform bacteria was found in large scale in water indicating contamination. 
 
 
Q3: What are the 3R’s in sustainable development? 
 
Answer: Reduce, Recycle and Reuse 
 
 
Q4: What are the two kinds of natural resources? 
 
Answer: Renewable and Non-renewable natural resources. 
 
 
Q5: What changes can you make in your habits to become more environment friendly? 
 
Answer: To become more environment friendly we should follow the 3R's (Reduce, Recycle and 
Reuse). 
1. Reduce: It means minimization of natural resources. We may do the following:

Q4: What are the two kinds of natural resources? 
 
Answer: Renewable and Non-renewable natural resources. 
 
 
Q5: What changes can you make in your habits to become more environment friendly? 
 
Answer: To become more environment friendly we should follow the 3R's (Reduce, Recycle and 
Reuse). 
1. Reduce: It means minimization of natural resources. We may do the following:  
1. Switch off lights, fans which are not required.  
2. Repair leaking taps and save water.  
3. Encourage solar cooker use and reduce LPG use.  
2. Recycle: Instead of extracting or creating new products from raw materials, we can collect old 
and used material (e.g. plastic, paper, metal, glass etc.) and recycle them to build products.  
3. Reuse: Reuse is better than recycle since recycling use some energy which can be save if we 
reuse the things again. E.g. bottle of consumed food products can be used to store things like 
salt, sugar, tea leaves etc.  
4. Educate and Create Awareness: We should educate our neighbourhood about environmental 
issues and take collateral measures collectively. E.g. we can help other in planting trees in 
our neighbourhood.  
Q6: List any two common methods by which solid wastes of urban areas are disposed off? 
 
Answer: Methods are: 
1. Bury in landfills  
2. composting  
3. recycle  
4. incineration (waste treatment)  
 
Nekchand's Rock Garden is the biggest outside art environment in the world based on reuse strategy.  
 
 
Q7: What is reuse strategy? Why it is considered better than recycling strategy? 
 
Answer: Reuse strategy means more than one use. Before discarding things like bags, containers, 
and other items, if these items are hygienic and we can reuse them for other activities. Reusing 
products extends their lives. As the process of recycling use some energy, the method of reuse is 
always 
considered better no energy is consumed. e.g. Pieces of coloured glass, cups and plates made of 
china clay, ceramic tiles, etc. can be used to make decorative wall pieces.
