The green house effect causes a global warming on the long term, and will damage fertile and densily populated areas in the world, and locally the Waddenzee and the Bieschbosch. International tourism comes with unnatural usage of enormous quantities of water, damage to shores and animal populations caused by building to close to the beaches. The tourism is the fastest growing segment in the air traffic, causing a double digit growth on airfields and related noise and dirty gasses. A local Dutch problem is the dense car traffic through the country. The highways have a wonderful quality, but there are so many cars that the traffic gets stuck every day.
Traffic jams occur daily.
The public transport system has a good quality compared with other countries, but it is very full, especially with commuters. The airport is so popular that several enlargements are being planned, including alternatives in the Northsea.
