What changes can you make in your habits to become more environmentfriendly?
The following changes can be made in our habits to become more environmentally-friendly:
(i) Segregate waste into recyclable and non-recyclable parts.
(ii) Instead of using vehicles walk for nearby places.
(iii) Don’t litter public places.
(iv) Minimize the use of plastics. It used reuse them.
(v) Switch off the lights and fans when not in use.
(vi) Reuse water from washing machines for cleaning purposes.
What would be the advantages of exploiting resources with short-term
The advantage of exploiting resources with short-term aims would be self-centered satisfaction. It will result in harming the environment and take a toll on nature’s health.
How would these advantages differ from the advantages of using a longterm perspective in managing our resources?
In the case of a long-time perspective in managing our resources, these resources can be used for the benefit of present generation and also conserved for the benefit of generations to come. This management of resources ensures uniform distribution of resources among the people.
Why do you think there should be equitable distribution of resources?
What forces would be working against an equitable distribution of our
Natural resources of Earth must be distributed among the people uniformly. By doing this, each one gets his/her share of the resource irrespective of power and wealth. The forces working against an equitable distribution of resources are human greed, corruption and inequality.
Why should we conserve forests and wildlife?
We should conserve forest and wildlife because of following reasons:
(i) Forests control flood, purify the air we breathe, prevent soil erosion and maintain its fertility.
(ii) Wildlife is a part of the ecosystem and disturbing their population would affect the food chain.
(iii) Tribal population depends on forests and wildlife in order to conserve their culture and tradition.
(iv) They are responsible for regular cycle of seasons as they maintain ecological balance.
Suggest some approaches towards the conservation of forests.
Some approaches towards forest conservation are as follows:
(i) More trees should be planted. Rate of forestation must be more than that of
(ii) Operations like improved cutting and selective cutting should be adopted by forest management.
(iii) Forest fires should be prevented.
(iv) Overgrazing should be prohibited.
(v) Forest rules and laws should be strictly enforced.
(vi) Avoid the wastage of timber and fuel wood.
Find out about the traditional systems of water harvesting/management in
The traditional systems of water harvesting/management in our region are
(i) Rooftop rainwater harvesting.
(iv) Surface runoff harvesting.
Compare the above system with the probable systems in hilly/mountainous
areas or plains or plateau regions.
In hilly regions, the canal irrigation system called Kulhs is used for water harvesting. In this system, the water flowing through falls, comes to the area located at lower regions through small human made drains. In the plains, the water harvesting structures are crescent-shaped earthen embankments. These are straight, low and concrete. So, the systems like Jhalaras and bewares are used here. In plateau regions, small pits are dug to collect water. Bandharas which are check dams or diversion are built across the rivers.
Find out the source of water in your region/locality. Is water from this
source available to all people living in that area?
The source of water in my region is river Narmada and ground water. After being treated, water is supplied to the residents through a water pipeline system.
The water from this source available to all people living in that area.
(Note: students should write about their own locality.)
What changes would you suggest in your home in order to be environmentfriendly?
I would suggest the following changes my home in order to be environment-friendly:
(i) Use separate bins for biodegradable and non-biodegradable waste.
(ii) Don’t waste food.
(iii) Follow three R’s Reduce, Recycle and Reuse.
(iv) Instead of private vehicles, try to use public vehicles.
(v) TV, fans, lights should be turned off when not in use.
(vi) Use energy efficient electrical appliances.
(vii) Use water and other resources judiciously.
Can you suggest some changes in your schools which would make it
Changes that can be undertaken in our schools to make it environment friendly are as follows:
(i) Turn off the tapes when not in use.
(ii) Leaking taps should be repaired to avoid wastage of water.
(iii) Students should bring their food in reusable boxes, not in plastic bags or in aluminum foil.
(iv) Enough trees should be planted in the school.
(v) There should be more windows in classroom for natural light.
(vi) Teachers should educate students about environment conservation.
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 produces? Why do you think so?
The Forest Department of Government should have the authority to decide the management of forest produces because they have sufficient power and resources that can manage the forest resources well. And also they are the caretakers of the forest land and are responsible for any damage to the forest.
How can you as an individual contribute or make a difference to the
