POINTS TO REMEMBER
Why do we need to manage our Resources?
■ Natural resources are the non-living and living components of nature which are being used or have the potential of being used by human beings for meeting their various needs
■ Soil, water and air are cycled over and over again in nature.
■ Sources may be (1) inexhaustible-water, air, solar energy or (ii) Exhaustible-which are likely to be exhausted with continuous exploitation, further of two sub-types (a) Renewal that are being replenished naturally e.g.. Forest, wild life, soil (b) Non-renewable-lack of regeneration likely to exhausted by continuous use coal, fossil fuels.
■ Need for judicious use of resources so as to sustain the resources for sustainable development and for conservation of environment.
■ Exploitation of resources is connected with environmental problems (accumulation of waste. depleting natural resources) which are global, national and local in nature. However IPCC (International panel on climate change) have formulated a number of international laws and regulations for safe guarding the environment and natural resource.

■ Our society is aware about these problems and some action is being taken. Ganga action plan is one of the actions. Ganga has been turned into a drain by hundred towns of U.P. Bihar and W. Bengal.
■ Discharge of untreated sewage, bathing, washing of cloth, castles, immersion of ashes, unburnt corpses, chemical effluents from industries have very badly degraded the quality of water in Ganga. It has resulted in killing of fish in most part of the river.
■ B.O.D. pH, COD of the water helps in quantifying pollution in the quality of water. pH can be early checked by pH universal indicator.
■Impact of environmental problems can be minimised by doing little things that make a great difference. We can save environment by observing three Rs-reduce, recycle and reuse.
■ Reduce-means useless, no wastage-switching off necessary light repairing leaky taps etc.

■ Recycle: using recycled plastic, paper, glass and metal products instead of synthesising or extracting fresh, need to segregate the waste that can be recycled.
■ Reuse is better than recycling, use a thing again and again instead of throwing away e.g.. Plastic bottle can be used for storing kitchen items, using paper envelopes by reversing.
■ Adopt a policy of making environment friendly decision while making everyday choices.
■ Concept of sustainable development encourages form of growth that meet current basic human needs while preserving the resource for the need of future generation. It needs change in all aspects of life, especially socio-economic and environmental conditions.
