Both the energy sources coal and petroleum take millions of years for their formation. As these resources are being utilised at a much faster rate than their formation, they will be exhausted in the near future, hence they need to be conserved.

(a) Put off the fans and lights when they are not required.
(b) Maximum use of solar radiation.
(c) Use of solar water heating system during winters.

We can conserve forests by the following methods:
(a) Silviculture is a programme started to replenish the forests by growing more trees and plants.
(b) Afforestation.
(c) Awareness programme- tree plantation (vanamahotsava) should be made more popular.
(d) Over-grazing by cattle should not be encouragded.
(e) Unauthorized felling of forest trees should be stopped.
(f) The plants useful for industry must be planted on waste lands.
(g) Local people should be employed to employed to protect the forests.
(h) Forest resources should be used in such a way that the environment is preserved and the benefit of the controlled exploitation go to the local people.

Forests and wildlife maintain an ecological balance of nature. It provides a great biological diversity. Wild life serves as a source for the domestication of animals and cultivation of crop plants. About 90% of the food plants originated from wild tropical ancestors. Many valuable products such as life-saving drugs, silk, lac, honey, feathers, musk, ivory etc., are obtained from wildlife. Forests and wildlife ensure a rich biodiversity on the earth. Loss of biodiversity leads to loss of ecological balance. Hence, we should conserve forests and wildlife.

A long term perspective in managing our resources would always be better than a short term perspective in the following ways:
(a)A long term perspective helps us in protecting our environment
(b)It conserves our natural resources
(c)It is ecofriendly
(d)It ensures that the future generations also get to enjoy the bountry of nature.

Exploitation of resources with short-term aims means misuse of the resource and harm to the earth for need and money.

The forest department developed a strategy in which the villagers were involved in the protection of the forest.

(a) Habitat, food, protection to wild life.
(b) Help in balancing CO₂ and O₂ of atmosphere.
(c) Improves water holding capacity of soil.
(d) Regulates water cycle
(e) For human being, they are the source for all essential commodities like, fuel wood, timber pulp and paper etc.
(f) It provides useful products like fruits, resins, gums, essential oils, bidi wrapper etc.

(a) recharging the ground water
(b) can be used for irrigation
(c) treated municipal water can be used for washing cars, watering the gardens
(d) certain pollutants in sewage water can be become fertiliser for various crops.

Reduce means to use a material/commodity in lesser quantity, e.g electricity and water. Reduce means a material that is used once is collected and sent back to a manufacturer so that they can make some other useful material from it. e.g., plastic cups and buckets, glass tumbler, paper, metal objects.
Reuse means using a thing over and over again instead of throwing it away. It does not involve the process of recycling either in small or large scale: e.g., used envelopes, plastic carry bags, bottles of jam.
