One paper from December 2014 estimated that over a quarter of a million tons of ocean plastic pollution was afloat. According to RanMarine, the WasteShark is available in both autonomous and remotecontrolled models. Measuring just over five feet by threeandahalf feet ( meters by meter), it can carry up to 352 pounds of rubbish ( kg) and has an operational battery life of 16 hours. By 2016 there were approximately 150 million tons of plastic in the world39。 WasteShark also has the abilities to gather air and water quality data, remove chemicals out of the water such as oil, and heavy metals, and scan the seabed to read its depth and outlines, said Oliver Cunningham, one of the cofounders of RanMarine. Fitted with a collisionavoidance system, the drone uses laser imaging detection and ranging technology to detect an object in its path and stop or back up if the object approaches.s around the perimeter (周邊) or through the city itself. The drones are that last line of defense between the city and the open ocean, added Cunningham. WasteSharks are operating in Dubai, South Africa and the Netherlands and cost $ 17, 000 for the remotecontrolled model and just under $ 23, 000 for the autonomous model. intention is to have the collected rubbish recycled or upcycled.

Then she and her 50 000 or so mates will hover in the dark all night every night, flapping their wings to create hot, breezy conditions to remove the water from the mixture.

By the age of one, they can recognise the significant noises around them and group them into a language. When we have lost this capacity as adults, it bees enormously difficult to distinguish between sounds that are glaringly different to a native speaker. It all sounds Greek to us. This is because the range of possible sounds that humans use to convey meaning may be as high as 2,000, but few languages use mo
