• 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.




                            Brainy Fact

                 Since 1870, global sea levels have risen by about 8 inches due to global warming. Arctic is one of the
                 worst places to be affected by global warming.



            Mining Activity

            Mining is the process of extracting useful minerals from the earth’s surface. It is estimated that two-thirds of the
            world’s yearly mineral production is done by surface mining. If we keep on extracting minerals from our natural
            resources, then it will create an ecological imbalance. So any country’s government allows only a limited number
            of mining activities to be done that too under its supervision. Sometimes humans for their own profits indulge in
            illegal mining without realising the importance of preserving these natural resources. A lot of legal or illegal mining
            activities all across the globe are responsible for significant environmental damage:




















               • 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.


                    Green Economy

            The term “Green Economy” was first coined in a 1989 report for the Government of the United Kingdom by a
            group of leading environmental economists, entitled "Blueprint for a Green Economy". There is no internationally
            agreed definition of a green economy but many countries have realised that the country’s economy and the
            balance in the environment go hand in hand. The United Nations Environment Programme (UNEP) has defined the
            green economy as “one that results in improved human well-being and social equity, while significantly reducing
            environmental risks and ecological scarcities. It is low carbon, resource efficient and socially inclusive”.
