Oceans are the best source of not only transportation but also of food, medicines and economic growth. They are the main component which balances the biosphere and ecosystem of the earth. Without oceans, life may cease to exist, affecting the survival of the human race. Hence, it is our prime responsibility to protect our oceans and keep it clean. Always remember that whatever we give to our Mother Nature will get credited back to us in future.
