Population : Earth has a limited carrying capacity.
If we take the scenario in India. It doesn’t seem to be going in the right direction. Even after a lot of effort, it is expected that India will be become the most populous country in the world by 2030. It is expected to be around 150 crores compared to the present population of 130 crores. In India, the most populated state in Uttar Pradesh. It was reported to be around 20 Crores in 2012. The least populated state in India is Sikkim. It was reported to be around six Lakhs in 2012.
Development and population control often go hand in hand. We can see this example in our own country. The southern part of India is supposed to be more developed than the northern part of India. It is also very clear from the data that the Southern part of India had started working on population control way back in the 1980s, and many of the major cities are in Southern India.
