The strategy of industrial growth between the period 1947-90 had its own set of advantages and disadvantages. While it did contribute to the growth and development of India's economy, it also had some negative effects. Let's take a look at some of the bad effects of this strategy:

1. Unequal distribution of wealth: One of the biggest negative effects of the strategy of industrial growth was the unequal distribution of wealth. The benefits of industrial growth were concentrated in certain regions and among certain classes of people, leaving behind large sections of the population. This led to a widening income gap between the rich and poor.

2. Environmental degradation: The focus on industrial growth led to widespread environmental degradation. Industries were set up without proper environmental regulations, leading to pollution and degradation of land, air, and water. This has had long-term negative effects on the health and well-being of the people living in these areas.

3. Dependence on foreign technology: Another negative effect of the strategy of industrial growth was the dependence on foreign technology. India had to import many of the technologies needed for industrial growth, which led to a drain on foreign exchange reserves. This also meant that India was not able to develop its own technologies and was dependent on other countries for its industrial growth.

4. Neglect of agriculture: The strategy of industrial growth led to neglect of agriculture, which was the backbone of the Indian economy. The focus on industries led to a decline in agricultural productivity and a neglect of rural areas. This led to a widening rural-urban divide and contributed to the migration of people from rural to urban areas.

5. Unemployment: While the strategy of industrial growth did create jobs, it also led to unemployment in certain sectors. The shift from agriculture to industry led to displacement of people from their traditional occupations, leading to unemployment and poverty.

In conclusion, the strategy of industrial growth between the period 1947-90 had some negative effects. While it did contribute to the growth and development of India's economy, it also led to unequal distribution of wealth, environmental degradation, dependence on foreign technology, neglect of agriculture, and unemployment.
