1 . The sea could be the food bowl of the future. In Jervis Bay, south of Sydney, seaweed, which is rich in fibre and omega 3, is grown and harvested.

Pia Winberg is a marine scientist who runs Australia's first food-grade fanned seaweed company. Her crop is grown alongside mussels (贻贝)and is used as an additive in pasta (意大利面)and other products.

Seaweed is also raised in large tanks, where it absorbs carbon dioxide waste from a wheat processing factory. The business is small, but could help to reduce the ecological footprint of traditional farming.

“We used ten percent of seaweed instead of wheat in breads and pastas, we've eliminated a million hectares of land, we've eliminated all of the carbon dioxide emissions associated with that, and we've also reduced the pressures on very precious fresh water.” said Pia Winberg.

Spiny sea urchins (多刺海胆虫)are another blue economy resource. They can destroy marine habitats, but a recent competition for environmental start-ups in Australia, saw them not as a pest but a delicacy (美味).

Martina Doblin, CEO of Sydney Institute of Marine Science, said, “By 2050 we will have some ten billion people on the planet, and about half the food they eat will come from the ocean. So, we really do need to pay attention to the way that we manage the blue economy-generating wealth from the ocean but in a sustainable (可持续的)way.”

Farming at sea has its challenges. Infrastructure (基础设施)has to be sound, as do supply chains and biosecurity. But get these things right, and the ocean might just be the next great economic frontier.

2 . Those who are concerned that robots are taking over the world can rest easy—for now. Though the androids have proved useful at performing ordinary tasks, they are not ready for the greatest time. At least that appears to be the case at Japan’s Henn-na Hotel chain where over half of the robot staff are being replaced by humans.

The first location of the unique hotel opened in July 2015 was at Nagasaki’s Huis Ten Bosch Theme Park. The hotel’s owner, Hideo Sawada, promised the hotel to be managed primarily by robots. Guests were greeted and checked-in by a dinosaur robot, while a cute android called Churi, placed inside each room, provided information about attractions. Not surprisingly, the lodging, recognized in 2016 as the world’s first robot-staffed hotel by Guinness World Records, drew in curious visitors from all around the world.

But as the years have passed, the hotel’s main draw is becoming less novel and more unsatisfactory. Also as the robots are “aging”, they are costing more to repair. Among the 283 androids being replaced are the chain’s two dinosaur receptionists. In addition to scaring young guests, they are also unable to photocopy guests’ passports, forcing human employees to step in each time. Also out are the cute Churi robots, which annoyed guests by interrupting their conversations. For example, one guest told The Wall Street Journal that Churi mistook his snoring for a command and kept asking him to repeat his request all night.

Sawada told The Wall Street Journal, “When you actually use robots you realize there are places where they aren’t needed—or just annoy people.” While Sawada may be cutting back on his use of androids, the recently-opened Smart LYZ Hotel and the Fly Zoo Hotel in China, are run entirely by robots, with not a human in sight. Whether the employees have more competence than those “hired” by the Henn-na Hotel chain remains to be seen.
