The summer is over, but the holiday season hasn’t stopped. Going on vacation is how many people calm down from a hectic work life and enjoy a good time. Cruise ships offer this experience all year round in the most naturally beautiful holiday destinations in the world: from the Arctic Circle or the Norwegian fjords to Mediterranean beaches. The urge to explore the world by cruise ship and see spectacular natural beauty has risen dramatically. Around 25 million people will board cruise ships this year, meaning the demand for such luxurious vacations has increased more than 68 percent during the last 10 years. Maybe you too would like to go on a cruise, but think twice: while you may be expecting to enjoy the fresh sea breeze, you are more likely to end up breathing in toxic pollutants.
