5.7.8. Protect Life Below Water

            Oceans, seas and rivers are home to more than 2 million estimated species. These underwater species provide life
            support and regulate our climatic conditions. We all need to conserve and consciously use the world’s ocean, seas
            and marine resources to make it sustainable for present and future generations.


            5.7.9. Protect Life on Land
            By stopping the cutting of trees and forest, land degradation, fragmentation and overgrazing will help in preserving
            and restoring the terrestrial ecosystems such as forests, wetlands, grasslands, drylands and mountains. Cutting of
            trees is leading to soil erosion and making land dry and unusable for cultivation.




                   Recap


               • Sustainable development is the development that satisfies the needs of the present without compromising the capacity of
               future generations, guaranteeing the balance between economic growth, care for the environment and social well-being.
               • Sustainable development provides initiation  and  approaches  for  development,  conservation  and  protection  of  natural
               resources to stop environmental degradation.
               • The Sustainable Development Goals also known as the Global Goals, are a universal approach for improving our world.
               These are 17 interconnected universal goals approved in 2015 by the United Nations General Assembly and are expected
               to be achieved by the year 2030.
