Dear student

10. C)

India’s population is increasing alarmingly. The current population of India has crossed one billion and is still growing. To meet the ever-increasing demand for food, we need more than a quarter of a billion tonnes of grain every year. This can be achieved by farming more lands and through systematic and proper management of production and distribution of food. However, in India, the agricultural land has already been cultivated intensively and there is no fresh land available for agricultural purposes. Therefore, it is necessary to increase the yielding efficiency of both crops and livestock.

So, it is important to keep in mind that improvement in food resources should be increased without disturbing environmental balance to meet ever increasing demand for food.
