The sources of water in my locality are groundwater through handpump and the municipality supply. Sometimes, especially in summer season, water from these sources becomes scant. In my locality, water is available to all the people.

1. Cutting valuable trees should be prevented.

2. We should use forest products, such that there should not be damage to the environment.

3. All people should participate in the conservation of forest and wild animals.

The commonly use method for birth control is barrier method in which a barrier is created which does not allow sperm to fertilise egg in the women in uterus. 

The various method include in Barrier method are: 

1. Condom: Rubber sheath is worn over the penis to stop sperm entering the vagina. 

2. Diaphragm: Rubber cup that is placed in the vagina over cervix. 

3. Intra-Uterine Contraceptive Device (IUCD): Copper-T is placed in uterus by doctor which prevent pregnancy.

(i) Roof top rain water harvesting. 

(ii) Watershed management.

Small scale and cottage industry.

There are large number of species of both plants and animals are found in the forest. However, the range of different life forms (bacteria fungi  ferns, flowering plants, nematodes, insects, birds, reptiles and so on) is also important. One of the main aims of conservation is to try and preserve the biodiversity we have inherited. Experiments and field studies suggest that a loss of diversity may lead to a loss of ecological stability.

The forests and wildlife should be conserved to prevent undue damage to the environment as  it helps in maintaining ecological balance in nature and preserves the gene pool.

Plateau is situated in the southern part of the state.

Plain is found in the eastern part of Rajasthan.

Silver bromide.

The main purpose of rain water harvesting is to make rainwater percolate under the ground so as to recharge ground water.

Rainwater harvesting.

It can be explained with one example—The great Himalayan Park contain alpine meadows which were grazed by sheep in summer. Nomadic shepherds drove their flock up from the valley every summer. When the National Park was formed this practice was banned. Because of no grazing, the grass first grew very tall and then fell over on the ground preventing fresh growth. Hence the traditional use was helpful for the forest maintenance.

Julius Caesar wrote ‘Gallic Wars’ and ‘Civil Wars’.

● Industries related to timber, paper, lac and sports equipment consider the forest as merely a source of raw material for their factories. 

● People who run these industries are influential people and obtain raw materials of the forest very cheap. 

● These industries are not interested in the sustainability of the forest in one particular area. 

● For example, after cutting down all the teak trees in one area, they move to farther away. 

● They do not bother about sustainable development

● Available natural resources must be distributed among the people uniformly so that each and every one gets his share of the resource. 

● Human greed, corruption, and the lobby of the rich and powerful are the forces working against an equitable distribution of resources.

● Forest is a natural habitat for a large number of species of plants (flora) and animals (fauna). 

● The biodiversity we have inherited should be conserved and preserved. 

● Loss of diversity may lead to loss of ecological stability. 

● Plants are producers, they produce food and release oxygen. The food is consumed by consumers (wildlife). 

● Wildlife provides stability to different natural processes of nature and decomposers decomposes (bacteria and fungi) the dead materials into nutrients. 

● Nutrients cycled back to the nutrient pool. 

● Therefore, we should conserve forest and wildlife to maintain the natural balance of our environment.

1. c. Management of forests according to the principles of sustainable development.

2. d. All of the above

3. a. Protection of ecologically important forest areas

4. b. To ensure that national forest certification systems meet our international requirements.

5. a. TRUE

There is absence of transport facilities in deserted hills, beehad and dang areas. The state roads are in very bad shape and the state is largely devoid of railway lines. Transport services are the nerve of state’s economic development, but are still a challenge for the state.

Natural resources are naturally occurring substances useful to man in their unmodified (natural) forms.

Persons having interest or concern for something are called stakeholders.

The occurrence of different types of genes and species from all the habitat and ecosystem in a particular place and various part of the earth is called biodiversity.

Maintaining biodiversity is important because experiments and field studies suggest that a loss of biodiversity may lead to a loss of ecological stability.

Forest is a house of diverse (different) species of plants, animals and all other sorts of living organisms. A biodiversity hotspot is given to the specific forests consisting of a richest diversity of species including most rare, vulnerable species of plants and animals and other organisms.

The three R’s means Reduce, Reuse and Recycle. Reduce means less use of resources like switching off lights, fans, television, computers, music players when not in use. Closing the taps while brushing teeth, repairing the faulty taps from which water leaks. Reuse means using things again and again like we can write on both sides of a paper, we can give our unused and old things to needy and poor people, bottles of jams, jellies, pickles when finished can be used to store other things etc. Recycle means using recycling technology new things can be produced from old ones like old newspaper, glass bottles, plastics etc. 3R’s approach is the best technique to save our environment.

Forest are referred as biodiversity hotspots.

Wildlife maintains an ecological balance of nature. It provides a great biological diversity. Many valuable products like musk, ivory, leather etc. are obtained from them. Forests provide us various valuable products like honey, medicines, lac, gums, resins, wood, prevent soil erosion and flood, brings rainfall, release oxygen to atmosphere which is a life supporter. Forests are habitat of variety of living organisms. Loss of biodiversity would lead to ecological imbalance so we need to conserve forests and wildlife.

Forests where a large number of flora and fauna species are found are termed as biodiversity hotspots. The criteria for measuring biodiversity are-

a. Number of species found in that area.

b. Range of different life forms like algae, bacteria, mosses, flowering plants, insects, animals, birds etc.

5. a. TRUE

The great Himalayan National park contains alpine meadows, within its reserved areas. These meadows were grazed by sheep in summer. Br.rt after the formation of national park, this practice was stopped. Due to this, the grass first grows very tall and then falls over preventing fresh growth from below.

 The conservation of forest and wildlife is necessary to restore the ecological balance.

Correct answer is b) M.N. Srinivas

The proper management of natural resources using it wisely and judiciously so that it is available for the coming generations also. All these resources are maintained. 

The population is increasing, demand for these resources is also increasing but they are limited in nature. 

The management would prevent the exploitation of these resources and keep them available for future generations. 

Forest—Many industries like timber, wood bidi, tendu leaves etc are dependent on the trees in the forest. They keep cutting the trees for use. 

This need to be managed properly and checked that new plantation of trees take place, animals are not harmed and are preserved. 

Wildlife—All animals in the forest are disturbed due to the intervention of people into the forest. They are also killed for trade of skin, fur, tusk horn etc. If the animals in the forest are not managed and taken care of then they will be extinct which will disturb the ecological balance of the earth. 

Water Resources—The main water resources are rivers, lake, ponds, underground water. The sources of water are getting polluted and the underground water is also discharged, used and the level of water is declining. Hence the recharge of water under the ground by rain water harvesting is necessary.

Our natural resources are limited. With the rapid increase in human population, due to improvement in health care, the demand for all resources is also increasing. Sustainable management is necessary to provide the economic well being to the present and the future generations and to maintain a healthy environment and life support system. 

Reuse can be practised by use, i.e., as we can reuse plastic bottles and envelopes.

1. c. 6 %

2. c. 6 %

3. d. All resources are equally divided

4. a. YES

5. a. TRUE

Two advantages:

(i) Provides the resources for the present generation

(ii) Preserve the resources for the future generation as well.

Reuse is better than recycling because it does not involve use of energy.

Sustainable management of natural resources is necessary to increase the overall life of natural resources especially non-renewable resources and also to control the environmental pollution. 

Both reuse and recycle are the good choices. 

Reuse : If we reuse something then the cost of recycle will be saved. 

Recycle : It is not necessary that each and everything can be reused, so after getting recycled the life of the resource will be enhanced.

Floods can be prevented by protecting wetlands and plant more and more trees strategically. Keeping a close eye on climate change.

Restore rivers to their natural courses and increasing water storage areas.
