At any level of development, human impact on the environment is a function of population size, per capita consumption and the environmental damage caused by the technology used to produce what is consumed. Population growth has a direct impact on sustainable development. Yet, very often the connection is not being made nor is it talked about. India is booming and sustainable development becomes increasingly more important, According to a United Nations report, India’s population currently encompasses about 1.2 billion people and is expected to grow by another 300 million within the next couple of decades. With cities generating two-thirds of the country’s economic output, an increasing number of Indians are leaving rural areas to seek employment in cities, relying on an efficient urban infrastructure. By 2030 it is predicted that 68 Indian cities will each have more than one million inhabitants, and six megacities, more than ten million each.
