World’s largest cruise ship sets sail from Miami

The world’s largest cruise ship has set sail from Miami, Florida, on its maiden voyage, but there are concerns about the vessel’s methane emissions. According to the BBC, the 365m-long Icon of the Seas has 20 decks and can house a maximum of 7,600 passengers. The vessel is going on a seven-day island-hopping voyage in the Caribbean. Environmentalists warn the liquefied natural gas-powered ship will leak harmful methane into the air. The ship, costing $2 billion, has over 40 restaurants, bars, and lounges.
