Board Exam Questions Reduce Reuse Recycle ICSE Class 10 Geography
Question. What are the three R’s of waste management ?
Answer: The three R’s are Reuse, Reduce amd Recycle of waste.
(i) Reuse : This includes the practise of using the things instead of throwing.
(ii) Reduce : This includes the practise of buying fewer things and using them for a longer period to avoid waste.
(iii) Recycle : It is using of waste materials and remaking some other article for use.
Question. Give three examples to show how social initiatives can help minimise the use of resources.
Answer: (i) They can take provisions for rainwater harvesting in their colonies to conserve rain water;
(ii) They can provide infrastructure for using solar energy in place of electricity;
(iii) They can make arrangements for collecting and segregating waste and turning the biodegradable waste into compost;
(iv) They can impose fines on those households which waste electricity and water.
Question. What harm is done to the environment by building big dams ?
Answer: (i) Building of a dam disrupts the ecosystem of the river and destroys the aquatic as well as terrestrial life around it.
(ii) Some environmentalists argue that dams intensify the effect of natural disasters like earthquakes.
(ii) For example, if an earthquake takes place, then along with the cracks in the ground, there would also be a flood and large pieces of the broken dam have to be coped with.
Question. What do you mean by recycling of waste ?
Answer: Recycling is the process of converting waste materials into reusable objects to prevent waste of potentially useful materials, reduce the consumption of fresh new materials.
Question. Give one example of reusing of waste.
Answer: (i) A beautiful garden (Rock Garden) has been created by Nek Chand in Chandigarh using waste products like tin cans, bottles, broken pieces of crockery etc.
(ii) Waste collectors, thus, help in making new production processes. Thus, they reduce the burden of waste disposal.
Question. Plant more trees.
Answer: Plant more trees, as trees can absorb toxic gases and purify the air by releasing oxygen.
Question. Use organic manure instead of chemical fertilisers.
Answer: The excessive use of chemical fertilizers create pollution. The fertilizers are used to enrich the soil, but they also contaminate the soil with impurities. On the other hand organic fertilizers enrich the soil without contaminating the soil with impurities.
Question. Explain how recycling of waste to produce paper can reduce deforestation.
Answer: (i) In India, we have tonnes of bagasse from sugarcane during a particular season.
(ii) Bagasse can be used in the manufacture of paper pulp. This would save trees which are normally used for making paper pulp.
(iii) In this way recycling of waste to produce paper can reduce deforestation.
Question. What is meant by Environmental Impact Assessment?
Answer: In order to minimise the adverse impact of a number of developmental projects on the environment like building large dams, railways, flyovers, canals and highways, the government ensures that an Environmental Impact Assessment is carried out before such a project is started.
Question. Use mass transport system.
Answer: If we use mass transport system, it would decrease the use of private vehicles on the road. This would reduce pollution.
Question. Explain the role of government in waste management.
Answer: The Government’s environmental policy focuses on the following areas :
(i) To check degradation of land and water through Wasteland Management and Restoration of river water quality programmes;
(ii) To provide for conservation of natural resources by direct action such as declaration of reserved forests, biosphere reserves, wetlands, mangroves and protection of endangered species;
(iii) To monitor development through Environmental Impact Assessment Studies of major project proposals; and
(iv) To make laws and acts for environment protection and to initiate penal measures against those who violate these laws.
Question. Name the sugercane waste which can be recycled into useful products.
Answer: Molasses and bagasse are the sugarcane waste which can be recycled in to useful product.
Question. Explain clearly how waste can be reduced by changing the process of production.
Answer: (i) By changing a modern method to make the best use of raw materials reduces the waste generation in industries.
(ii) In zinc electroplating chlorides are used in the process instead of using the sulphate salt in order to eliminate the production of cyanides.
Question. Why are recycled plastic bags considered harmful for the environment ?
Answer: (i) Plastic is non-biodegradable. The bonds of carbon in plastic are impossible to break down through a physical or chemical process. They have to be incinerated, recycled or buried in landfills.
(ii) The plastic bags which are extensively used in India are made from recycled plastic.
(iii) The recycled plastic bags are harmful because the melting of plastic and plastic products breaks some polymer chains into smaller units which are harmful.
Question. Explain how reusing waste can reduce the burden of waste disposal.
Answer: When we reusing the waste to produce something new out it then it will reduce the waste disposal. Example flyash can be used for making bricks and filling roads.
Question. What can an individual do to reduce waste ?
Answer: (i) Use carry bags made of paper or cloth instead of polythene.
(ii) Help more in pollution prevention than pollution control.
(iii) Use eco-friendly products.
(iv) Cut down the use of chlorofluorocarbons (CFCs) as they destroy the ozone layer. Do not use Styrofoam cups that have chlorofluorocarbon (CFC) molecules in them which destroy ozone layer.
(v) Use chemicals derived from peaches and plums to clean computer chips and circuit boards instead of CFCs.
(vi) Use CFC-free refrigerators.
Question. Name the processes involved in reducing the waste.
Answer: (i) Change of Process – By changing a modern method to make the best use of raw materials.
(ii) Waste Concentration – By using scientific techniques.
(iii) Segregation of Waste – By seperating the waste.
