(C) Encouraging the usage of personal vehicles

The country in which the iron produced comes from recycled automobiles is Japan

The mining method Mountain Top Removal mining devastate the environment. They destroy soil, plants and animal habitats.

Seeds from the Jatropa Curcas plant are used for the production of bio-fuel.

Answer is (A) Jatropa

Harm to animals that may be forced to find new habitats. If we damage a forest resource indiscriminately the depletion of resources occur and we may have to face problem for water and timber in future.

C) Jatropa, Pongamia

Correct option is C) petroleum

If the forest area decreases

1. It destroys wildlife habitat. 

2. It increases soil erosion. 

3. It releases green house gases into the atmosphere contributing to global warming. 

4. It also harms people who relay on forest for their survival, hunting and gathering, harvesting forest products or using timber and firewood.

Answer is (D) All

The reason for Ramaiah making broad bed furrow around his field was, it is useful to conserve soil and water, fertilizer application weeding operations. It also conserves rain water. 

The farmers are over coming the water scarcity by sharing water available in the village. They formed groups of farmer including large and small ones who would use the same water resource. Farmers were also motivated to use irrigation techniques like drip irrigation.

If the temperature on earth increases, the consequences would be as follows. 

a) All the glaciers and the frozen ice in the polar region start melting leading to rise in the sea water levels. 

b) It results in the submergence of low lying coastal areas throughout the world. Millions of people of those areas would lost their homes. 

c) Changes in rainfall patterns take place and it result in the occurance of droughts and decrease in crop production. 

d) Global warming results in climate change which cause the breakout of climatic sensitive diseases like Malaria, Dengue, Diarrhoea, etc.

The consequences of rapid decrease of Natural resources. 

1. The resources scarcity will arise shortly and demand for them will increase.

2. Future generations may not get these resources. 

3. Vehicles running with fossil fuels become useless. 

4. All the industries that depend on these sources will shutdown.

5. Electricity production through these sources will be stopped. So we have to stay in dark during night. 

6. All the utensils and other articles should be made out of recycled materials. 

7. Balance in the nature will be disturbed due to decrease in these sources like forest and biodiversity. 

8. We have to search for other sources as the alternative for these resources.

1. Due to over drilling of borewells and pulling out water by electric motors, the ground water level Is decreasing day by day. 

2. It Is goes on without recharging, ground water becomes scarce. 

3. It shows impact on agriculture and the productivity will decrease. 

4. Fluorine levels In ground water will increase. 

5. Sometimes, saline water may intrude Into the interior places of land and water becomes unfit for consumption. 

6. Farmers have to drill the bore wells to more depths which Increase the losses for them.

Correct option is B) mining
 

When we use the environment In ways that ensure we have resources for the future, It Is called sustainable development. It Is needed because development and conservation can coexist In harmony.

Sustainable development: When we use the environment in ways that ensure we have resources for the future it is called sustainable development.

Correct option is C) development without damaging

84% of wells have been.converted to bore wells.

Open wells have dried up, water tables have gone down.

False 

Heating of air causes an increase in the kinetic energy of vapours to present in the air due to which they get lighter and moves up at a higher altitude. While lowering of temperature at higher altitude cause condensation of water vapors.

1. Use Biofuel – Reduce Fossil Fuel. 

2. Use alternative resources – Save the environment.

a) Save forest, forest will save you. 

b) Grow the plants and get the fresh air.

Slogans: 

1. Waste water today – live in desert tomorrow 

2. Practice eco-friendly methods.

3. Use natural resources judiciously. 

4. Save nature – Save future.

The resources which reproduce themselves as per usage during a specific time or they are inexhaustible are called renewable resources, e.g. forests, solar insolation, animals, birds, etc.

1. Gives energy quickly 

2. Easy to store and transportation is easy. 

3. High efficiency 

4. Leaves no residue

Renewable resources: Any natural resource that can be replenished or replaced naturally after they are used is called renewable resources. e.g.: Soil, water, plants, etc.

An example for renewable resources is Solar energy.

Petrol and Kerosene are Non – renewable forms of natural resources.

(a) maintain biodiversity

Natural resources are naturally occurring substances that are considered valuable in their natural form.

The rule of formation of such minerals is very slow compared to the rate at which they are being used by human Such resources which cannot be replenished. Once depleted are called Non renewable resources.

Resources that get replenished in nature are called Renewable natural resource.

1. gifts

2. renewable resources

3. non-renewable

4. greater

5. conservation of resources.

6. 50% more natural resources of

Water Resources: Water is a unique liquid because there is no alternative for it. It is essential for all forms of life. Compared to most other liquids, water has a high capacity to absorb or store heat.

Water is a major body constituent of several plant and animal species. Seventy percent of the human body consists of water. Humans use water for several purposes—domestic (drinking, cooking, washing, etc.), agricultural (irrigation), industrial and generation of electricity.

1. Yes, we are also an important resources of nature. 

2. Human beings, through the labour they provide and the organizations their staff are also considered to be resources. 

3. The term human resources can also be defined as the skills, energy, talent, abilities, and knowledge that are used for the production of goods or the rendering of service. 

4. In a project management context, human resources are those employees responsible for undertaking the activities defined in the project plan.

1. In my house 900 litres of water is being used per day at the average of 225 litres for a person per day (4 members family). 

2. Actually this much water is not required. 

3. We can conserve at least 400 – 500 litres of water at the average of 100 to 125 litres per head. 

4. In India, the design of water supply system has been done using certain standards. 

5. Currently the standard being used is BIS 1179 : 1993, reaffirmed in 1998. 

6. According to this, for communities with a population between 20,000 to 1,00,000 – 100 to 150 litres per head per day can be considered.
