Urbanization, the growth of cities due to migration and population increase, can strain resources and infrastructure. Environmental impacts include increased pollution, loss of green spaces, and higher energy consumption. Quality of life can decline due to overcrowding, traffic congestion, and inadequate housing or sanitation. However, urbanization also brings opportunities for economic growth, innovation, and cultural exchange. Sustainable urban planning, including green spaces and efficient public transport, is key to mitigating negative effects.
