This is height of pessimism. ARe you living in 19th century? in 21st century, India's young population is seen as it biggest advantage. It 300 million strong middle class has become the most attractive for the other countries as there is not other country with such a huge population with purchasing power. while Europe is facing the problem of greying population and fewer younger people it will be countries like India and China who will inherit the world. If you are afraid that you might not get to eat because of our increasing population migrate to iceland. for Indians there will be no dearth of food as long as long as they are ready to hard work. Produce more children and enjoy the life should be the motto (only if you have guts).
