Planning a cruise vacation? If you're setting sail with Royal Caribbean Cruises (which also operates Celebrity Cruises and other lines) or Norwegian Cruise Line Holdings (which runs its namesake line, along with Oceania Cruises and Regent Seven Seas Cruises), the two companies have some good news on the ocean conservation front.

First, Royal Caribbean announced on June 8th that they will eliminate plastic straws on their ships by the end of 2018. "Healthy oceans are vital to the success of our company," said Richard Fain, Chairman and CEO, Royal Caribbean Cruises Ltd. in a company press release. "For over 25 years, our Save the Waves program has guided us to reduce, reuse, and recycle everything we can. Eliminating single-use plastics is another step in that program."

"The success of our business is dependent on the health of our oceans and, together with Ocean Conservancy, we are taking a step forward in our commitment to protect the world’s oceans," said Frank Del Rio, president and chief executive officer of Norwegian Cruise Line Holdings Ltd. in an official statement, also released on June 8th.  “We are excited to lead the cruise industry by joining the Trash Free Seas Alliance® and support Ocean Conservancy’s vision of a world with waterways, beaches and oceans free of plastic waste.” Learn more about the company's environmental initiatives at nclhltd.com/Stewardship.
