(i) We have to control the consumption of water as an example we should not leave the tap running while brushing the teeth.We have to fix the leakage of pipe and tap without delaying .
(ii) The production of electricity is required huge amount of coal and hidal projects are limited in number that required huge space and money to build up so we have to control the consumption of electricity,we should not leave the fan,cooler,AC and bulbs running unecessarily.
(iii) We should walk by feet or throgh bycycle to the places which are located near us that will save petrol and electricity.We should also try to use public vehicles while going to office or to visit somewhere that will minimize polutions.

Q2.What would be the advantages of exploiting resources with short-term aims?
Ans. The exploitation of resources with short term goal will increase rate of development in the industrial field and improve the living standard of the people,the overall economy would be rised up but resources are non sustainable therefore the depleteion of resources will lead our future generation in risk,so the uses of resources should be planned for longer term so that other alternatives could be explored.
Q3.How would these advantages differ from the advantages of using a long-term perspective in managing our resources?
Ans. It is more advantageous to use the resources for long term perspective because in this method other alternatives can be found .Longer term perspective of using resources will develop our economy in a sustainable way.The conservation of the resources will fulfil the requirement of future generation also.

Q4.Why do you think that there should be an equitable distribution of resources? What forces would be working against an equitable distribution of our resources?

Q2.Suggest some approaches towards the conservation of forests.
Ans. Some of the steps suggested here for the conservation of forests are following
(i) The villagers are requested to use LPG as a fuel for cooking the foods instead of the wood they get from the tree or plants.
(ii) There should be regular program for the plantation of the trees,for this government should hire villagers,in this way they can get employment and inspiration to grow tree.
(iii)All the forests should be supervised by the goverment by employing the security forces.
