In recent years, many health and environmental experts have expressed concern about air quality and the overall quality of life in large cities.
Due to the fact that environmental standards are not observed, many populated areas are becoming hazardous to health.
However, there are also real "oases" in terms of favorable living conditions.
Denmark is generally considered a country with an excellent environmental situation, but Copenhagen can safely be called a real standard. There is a relatively small amount of motor transport in the city, as bicycles are mainly used.
Copenhagen also has many green spaces that help clean the air.
Finland as a whole is a country with beautiful nature and excellent ecology. Such success was achieved thanks to the reduction of the amount of personal transport.
The needs of the population are almost completely satisfied by public transport.
New Zealand is an example of unique nature, which they are trying to preserve with all their might. Also, this country is extremely responsible in observing environmental standards.
This makes Auckland one of the cleanest cities on the planet.
