Question 1:

What changes can you make in your habits to become more environment friendly?

Answer:

To become more environment friendly we can make following changes in our habits:

  1. Separate recyclable from non-recyclable garbage.
  2. When not in use, turn off the lights, fans, television, and other electrical devices.
  3. Utilize energy-efficient electrical devices.
  4. Walk to neighboring stores rather than take a car.
  5. Reuse washing machine water for cleaning.

Question 2:

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

Answer:

The benefits of using resources for short-term goals include the following:

  1. It will be advantageous for the current generation to exploit resources for short-term goals.
  2. It will aid in accelerating the nation's economic expansion.
  3. It will help the nation's industrialization.
  4. It aids in meeting the immediate requirements of people.
  5. It will speed up current progress, expansion, and development on both a personal and societal level.

Question 3:

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

Answer:

The current generation can use resources effectively for growth and development if they follow short-term goals. However, if we use resources for long-term goals, the following generation will also be able to use them to meet their requirements.

Long Term Perspective:

The conservation of resources so that future generations may use them is made possible by the long-term model of resource utilization. As a result, the economy will be able to expand for longer. Additionally, it gives technology more time to develop and find new, sustainable energy sources (such as nuclear fusion and fuel cells). Overall, the long-term perspective in resource management offers a major benefit over the short-term approach.
Therefore, it would be wiser to utilize our natural resources in a way that will allow them to be used by the current generation while also being preserved for use in the future. However, because resources are finite, it will prevent future generations from enjoying the advantages of these resources.

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:

Equitable Resource Distribution:

Equitable resource distribution ensures that everyone has access to the needs of life while allowing each person to get their fair share of resources (such as food, water, shelter, etc.).

The forces that operate against equitable distribution:

  1. Resource allocation across regions (such as soil and minerals).
  2. The unequal distribution of resources between the wealthy and the poor.
  3. Greed and corruption among some people

Therefore, it is necessary to divide the planet's natural resources equally among its people to ensure everyone gets their fair share. Human greed, corruption, and the power lobby thwarted a fair allocation of resources.

Question 1:

Why should we conserve forest and wild life?

Answer:

We should conserve forest and wild life because:

  1. They contribute to preserving an area's ecological balance.
  2. They give us items like rubber, wood, dyes, gum, resin, oil, fibers, medications, wax, honey, fruits, seeds, bidi leaves, etc., that are beneficial.
  3. They maintain the fertility of the land, reduce flooding, and purify the air.
  4. Forests protect genetic resources and biodiversity. Damage to diversity leads to an imbalance in ecological stability.

Question 2:

Suggest some approaches towards the conservation of forests.

Answer:

Some methods for forest conservation are as follow :

  1. There should only be a prohibition on chopping down certain trees in the forest. Forests stop soil erosion.
  2. It is important to prevent forest fires. Fires cause extensive forest loss.
  3. Insects and pests should be kept out of forests. Spraying pesticides and insecticides in woods are recommended.
  4. Overgrazing ought to be outlawed.

Question 1:

Find out about the traditional systems of water harvesting management in your region.?

Answer:

Many of us reside in urban areas where municipal agencies provide water. Rainwater harvesting systems are placed in the homes, collecting the runoff and channeling it into a dedicated pit. This promotes groundwater recharging.

In soak pits, efforts are undertaken to collect runoff from the rain. The water table may rise due to this water's ability to enrich subsurface water.

Rooftop runoff water can also be collected in ditches designed to raise the subsurface water table.

Question 2:

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

Answer:

Drinking water system in hilly areas:

  1. In hilly regions like Himachal Pradesh, kuhl irrigation systems were traditionally used. In this system, little drains constructed by humans transport water from falls to villages situated in lower regions.
  2. In Meghalaya, bamboo drains transport water to the lower areas of the hills.

Drinking water system in plains:

  1. Jhalaras were created in Gujarat and Rajasthan primarily for communal use and religious ceremonies.
  2. Bawaries and other water supplies were created in several locations.

Drinking water system in plateau regions :

  1. Bandharas are diversion or check dams constructed across rivers. Maharashtra had such a conventional system.
  2. Small pits were excavated to collect water in some areas.

Question 3:

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

Answer:

The Yamuna River, the upper Ganga Canal, the Bhakra Storage, and groundwater are our area's primary water sources (Delhi). Residents are provided with treated water through a network of water pipes.

Everyone who resides in the neighborhood has access to water.

(Caution: Students must write about the area (the region around them).
