Final answer:
The migration of farmers and others to urban areas has increased pollution in the cities due to the increase in demands for resources.
Step-by-step explanation:
The migration of farmers and others to urban areas can affect the environment by increasing pollution in cities. Urbanization often leads to higher levels of industrialization, increased vehicular traffic, and the concentration of people and activities.
These factors contribute to air and water pollution, as well as other environmental issues. The demand for energy, resources, and infrastructure in urban areas can result in environmental challenges, including increased emissions of pollutants and the generation of waste. Therefore, the movement of people from rural to urban areas can have significant implications for the environmental quality of cities.
