The Visible Cost of Urbanisation
Densification, also called urbanisation, is a double edged problem. The first problem is that bringing more people closer together you increase noise pollution. The more people live nearby, the more people need to learn to be quiet. The second cost is an inability to shelter from the heat on a hot summer’s day.
In Paris, Geneva, Nyon and London plenty of people have moved from villages and houses to apartments. The result of this migration from a multi-level house to a single floor apartment is that during a heatwave people are stuck in hot apartments with nowhere to flee.
