In-Text Questions (Page 271)

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

Answer 1:
In order to become more environment-friendly, the following practices can be incorporated in our day-to-day lives:

1.Turning off any electrical appliance (such as TV’s, water heaters, lights, fans, and air conditioners) when they are not in use.
2.Avoiding the wastage of water by fixing any leaking taps or pipes as soon as possible. Also, the amount of water consumed must be controlled. For example, the tap should not be left running while brushing teeth.
3.Disposing of plastic and glass wastes in recycling bins (many plastics take a long time to decompose and can have adverse effects on the environment).
4.Using recyclable and eco-friendly products instead of the convenient plastic products. For example, using paper or cloth bags instead of polythene

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

Answer 2:
Overconsumption of resources with short-term interests in mind will give a boost to the economy. However, the increased growth of the economy will be short-lived since the exploitation of resources is not sustainable. Exploiting resources for the sake of short-term goals will be beneficial to the present generations but not for future generations.

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

Answer 3:
This way the resources can be used for the benefit of the present generation and also conserved for the benefit of generations to come. This ensures uniform distribution of resources among the people.

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 4:
There should be equitable distribution of resources so that all, rich, powerful and poor people get benefit from the development of these resources. Rich, greedy and powerful people could work against an equitable distribution of our resources.

In-Text Questions (Page 275)

Question 1:
Why should we conserve forests and wildlife?

Answer 1:
The conservation of forests is very important for the stability of the environment. Forests serve as a home to a huge variety of life-forms. Destruction of these forests can disturb the food chain and lead to the extinction of many important species. Also, forests protect the soil from erosion and play a vital role in the water cycle. The loss of forests can severely affect the day-to-day lives of humans.

Question 2:
Suggest some approaches towards the conservation of forests.

Answer 2:
Some methods for forest conservation are as follow :

1Only except some trees, there should be ban on cutting of forest. Forests stop soil erosion.
2.Forests should be saved from fires. Many forests get destroyed due to fires.
3.Forests should be saved from pests and insects. Pesticides, insecticides should be sprayed in forests.
4.Overgrazing should be prohibited.
5.National rules and laws should be strictly enforced.

In-Text Questions (Page 278)

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

Answer 1:
Many of us live in cities, where water is supplied by the municipal authorities. In the houses, systems of rainwater harvesting are installed which collect the water running off and channel it into a special pit created for the purpose. This helps to recharge ground water.
Efforts are being made to collect run off rain water in soak pits. This water enriches underground water and can cause rise in water table.
Run off water from roof tops can also be collected in trenches, specially made to enrich underground water table.

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

Answer 2:
In hilly regions, rainwater is often collected and channelled with the help of a stream. The stream is diverted to different areas with the help of canals for the purpose of irrigation. In mountainous regions, water is commonly obtained from the rivers that flow from the glaciers.

In the plains, water is obtained from many natural sources such as lakes and rivers. Groundwater is also harvested with the help of borewells for irrigation and human consumption.

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

Answer 3:
In metropolitan cities, the primary source of water is groundwater. This water is made available to all people in the city. However, poor infrastructure in some localities makes it difficult for some people to obtain the water.
