Monaco is noted for its beautiful natural scenery and mild, sunny climate. The principality has sponsored numerous marine conservation efforts. Its own environment is entirely urban. According to UN reports, Monaco's environmental circumstances are very good. The nation has consistently monitored pollution levels in its air and water to ensure the safety of its citizens. One-fifth of the nation's land area (1.95 sq km) and two marine areas are protected by environmental statutes.
The government has also instituted a system of air pollution control facilities controlled by the Environmental Service. Citizens are encouraged to use public transportation to limit the amount of gas emissions.
Similar techniques have been applied to the protection of Monaco's water supply. Noise levels from industry and transportation are also monitored to ensure safe levels.
Monaco also has a sea-farming area which annually produces 800 tons of fish grown in clean water. Monaco is known for its activity in the field of marine sciences. The Oceanographic Museum, formerly directed by Jacques Cousteau, is renowned for its work and exhibits on marine life.
