Q-3 Explain the importance of forests.
Q-4 How can we preserve and conserve our natural resources?
Answers
Answer:
A resource is a source or supply from which a benefit is produced and that has some utility. Resources can broadly be classified upon their availability — they are classified into renewable and non-renewable resources. ... An item becomes a resource with time and developing technology.
Explanation:
The importance of forests cannot be underestimated. We depend on forests for our survival, from the air we breathe to the wood we use. Besides providing habitats for animals and livelihoods for humans, forests also offer watershed protection, prevent soil erosion and mitigate climate change.
Answer:
b) Define the term Resources.
Everything available in our environment which can be used to satisfy our needs, is called a resource. It should be technologically accessible, economically feasible and culturally acceptable. Only then, it can be termed as a ‘Resource’. Examples: minerals, forests, fossil fuels etc.
Classification of Resources:
(a) On the basis of origin: Biotic and Abiotic.
(b) On the basis of exhaustibility: Renewable and Non-renewable.
(c) On the basis of ownership: Individual (Personal), Community, National and International.
(d) On the basis of status and development: Potential, Developed, Reserve and Stock.
Biotic Resources are obtained from the biosphere. They have life or are living resources, e.g., human beings, fisheries, forests, etc.
Abiotic Resources include all non-living things, e.g., rocks and minerals.
Renewable Resources:
The resources which can be renewed or reproduced by physical, chemical and mechanical processes are known as renewable or replenishable resources, e.g., water, wildlife, forests, solar energy, wind energy, etc.
Non-renewable Resources:
The resources which once get exhausted, cannot be remade. They take a long geological period of time, i.e., millions of years in their formation, e.g., minerals, fossil’ fuels, etc.
Individual resources: Owned by individuals, e.g., own land, house;
Community Owned Resources: Resources which are accessible to all the members of the community, e.g., parks, playground;
National Resources: Resources which belong to the nation, e.g., roads, railways; and
International resources: Resources which no individual country can utilize, e.g., oceanic waters beyond 200 km.
Potential resources: Resources found in a region but not in use, e.g., solar energy in Rajasthan,
wind in Gujarat;
Stock: Resources available but do not have appropriate technology to access, e.g., lack of technical know how to use hydrogen and oxygen as source of energy; and
Reserve: Subset of stock. Can be used for future needs, e.g., water in the dams, forest resources.
-3 Explain the importance of forests.
The importance of forests cannot be underestimated. We depend on forests for our survival, from the air we breathe to the wood we use. Besides providing habitats for animals and livelihoods for humans, forests also offer watershed protection, prevent soil erosion and mitigate climate change.
How can we preserve and conserve our natural resources?
Resource conservation means using the available resources carefully and giving them time to get renewed. Sustainable development means balancing our present needs of using resources without compromising the ability of future generations to meet their own needs.
The golden rule of conservation is - the three R’s – Reduce, Reuse and Recycle.
Reduce consumption and wastage of resources. The second step involves reusing resources, instead of throwing them away after one use. Recycling reduces pollution, and wastage of energy and raw materials.
The future of our planet and its people depends upon how we maintain nature’s life support system.
It is our responsibility to preserve and conserve the resources by sustaining the natural resources, conserving the diverse forms of life on earth, and minimizing damage to the environment.
