8.   Name any three components of the Green Economy.
          Ans.  •  Renewable Energy.
              •   Green Buildings.
              •   Green Transport.
            9.   What is the Green Skills Development Programme?
          Ans.  The government of India launched the Green Skills Development Programme (GSDP) in India in the year 2017. This was
              started by the Ministry of Environment, Forest and Climate Change (MoEFCC) in partnership with National Skill Development
              Agency (NSDA). It aims to develop green skilled workers having technical knowledge and commitment to sustainable
              development.
          10.   Define Green jobs? Give Example.
          Ans.  People possessing Green Skills are getting jobs in the fields of agriculture, manufacturing, research and development
              (R&D), administrative, and service activities that are aimed at sustaining and protecting the environment. These jobs are
              called Green Jobs.
          11.   What do you mean by Renewable Energy? Give Examples.
          Ans.  Energy produced by renewable sources like wind, sun, water, etc. is called renewable energy.

        B.   Long answer type questions:

            1.   Explain two types of ecosystem with examples.
          Ans.  The two types of ecosystem are:
              •  Artificial: An artificial ecosystem is a human made system of plants, animals and people living in an area together with
                their surroundings. For example, zoo parks often create artificial ecosystems by placing animals in human-made areas
                similar to their natural habitat.
              •  Natural: A natural ecosystem is a community of living and non-living things that interact with each other for their
                existence and maintain an ecological balance without human intervention. Natural ecosystems can be divided into
                terrestrial and aquatic.
            2.   What are the main causes of Global Warming?
          Ans.  •   Excessive use of fossil fuels like coal, oil and natural gas produces greenhouse gases-like methane, nitrous oxide and
                mainly carbon dioxide which trap the sun’s radiation within the atmosphere resulting in rise in global temperature.
              •  Trees absorb CO  from the atmosphere and release oxygen instead, so they work as air purifiers. Deforestation due to
                             2
                urbanisation and industrialisation has reduced the number of trees on the earth. This has resulted in the increase of
                carbon dioxide level in the atmosphere.
              •  Overconsumption of natural resources due to population explosion has also contributed to global warming.
              •  Increase in pollution is also responsible for the rise in global warming.
            3.   How mining activities all across the globe are responsible for significant environmental damage?
          Ans.  •   Acid mine drainage, which is the formation and movement of highly acidic water rich in heavy metals, contaminates the
                surrounding water bodies.
              •  Mining can deplete surface and groundwater supplies.
              •  To get the land for mining, the forest in that area is destroyed. This has a negative impact on the plants and animals living
                in that region.
              •  When the mining is over and that area is abandoned, then it creates wastage of land which is suitable neither for
                industrial use nor for agricultural purpose.
            4.   Give three important characteristics of the Green Economy.
          Ans.  The three important characteristics of the Green Economy:
              •  Renewable Energy: Energy produced by renewable sources like wind, sun, water, etc. is called renewable energy. Using
                these as the alternate sources of energy will help reduce the impact on the environment.
              •  Green  Buildings:  Buildings  which  cause  minimum  destruction  of  the  environment  during  its  construction  and  use
                renewable energy with proper waste management are called Green Buildings.
