The innovators claim this biodiesel can be used in regular diesel car engines, with little or no modifications. FIRST OFFSHORE WIND FARM (US) G eneral Electric and Deepwater Wind collaborated to de- velop America’s first off- shore wind farm near Block Island. It generates a combined 30 megawatts of electricity — enough to supply 17,000 homes — and turn Block Island into the most powerful coastal en- clave in the northeast. FLOATING WIND FARM H ywind is the first of its kind 30 MW floating wind farm off the Aberdeenshire coast in Scotland. And no don’t worry, it won’t float away. It is held in place by suc- tion anchors on the seabed and can power 20,000 households for a year.

DO IT YOURSELF Use fish waste to grow over 40 vegetables in a rice box I t’s time we stopped wor- rying about the soaring prices of fruits and veg- etables. There’s a sim- ple and inexpensive way to beat inflation – by growing them organically with fish, at home. And you don’t need a large farm for it either. All you require is an aquarium, a rice box and less than 2 sq feet space. Azlan Shakib, a former en- gineer who quit his job to get into agriculture ex- plained that any- one can take up this DIY proj- ect and grow practically all kinds of vegetables and fruits in- cluding let- tuce, bananas, capsicum and other leafy veg- etables at home with- out the use of soil. “The process I am talking about is called aquaponics where we try to establish a sym- biotic relationship between fish and plants,” said Shakib. The technique also saves water as you don’t need to clean the aquarium every day. Where to start 1. To begin with, you need some colourful fish and an aquari- um. It can be done with a single fish too but having more always helps the plants to thrive better. Many people use a rice box and turn it up- side down to grow plants. 2. Create a bed and plant the seed in water. Then you will need an aquarium water pump with a motor. Set it up by con- necting the aquarium and the plant bed using motor. The sys- tem is automatic. 3. Lastly, take the time in the morning to feed the fish as they will eat the food and pass on the waste in water. This will be passed on to plants which absorb the nitrates, recycle the water and send it back to the aquarium. Aquaponics doesn’t need much space. Beginning with a 2 sq-ft space you can go all the way to a much larger area depending on what you want to grow. BI Hunters have almost wiped out the narwhal population. The ‘unicorns of the sea’ are now in the ‘Red List’ of endangered species, warn experts N arwhals, a type of whale with a tusk that grows up to 10 ft long, lives in the Arctic waters around Canada, Greenland, Norway and Russia. EXCESSIVE HUNTING The elusive creatures, dubbed ‘unicorns of the sea’ were added to the ‘Red List’ of endan- gered species in 2008. But a scientist who has worked in Greenland said the country’s gov- ernment was failing to protect them. He said: “There is a very serious develop- ment with narwhals on the east coast of Greenland. Not only have these creatures been impacted by climate change, popu- lations are being decimated due to ex- cessive hunting quotas.” DWINDLING NUMBERS In 2008 marine biologists estimated there were just 1,945 narwhals remaining in the region. But by 2017 the number was down to 246. And since then, Green- landic catchers have further reduced their numbers. The World Wildlife Fund estimates fewer than 80,000 remain world- wide. Narwhals have long been prized for their blubber and ivory from their tusks. In 2004, Greenland set its first hunting quotas and banned the export of tusks, halting a thousand-year-old trade. In a report last month the North Atlantic Marine Mammal Commission said no narwhals should be hunted off Greenland’s east coast from next year.

Listen to the science Palau, which lies in western Pacific ,about halfway between Australia and Japan, is renowned for its marine life and is regarded as one of the world’s best diving destinations, but the gov- ernment is concerned its popularity is coming at a cost. According to Re- mengesau, there was scientific evi- dence that the chemicals found in most sunscreens were toxic to corals, even in minute doses. With Palau’s popular dive sites packed with tourists, there are con- cerns a build-up of these chemicals would irreparably harm the reefs. From New Year’s day, any reef-toxic sun- screen imported or sold in Palau will be confiscated with an additional fine of $1,000 for the owner. “When science tells us that a practice is damaging to coral reefs, to fish population, or to the ocean itself, our people take note and our visitors do too,” Remengesau said. Marine sanctuary Along with the sunscreen ban, Palau’s much-touted marine sanctuary came into effect on January 1, closing 80 per cent of its exclusive economic zone (EEZ) to fishing and other marine ac- tivities including mining and shark finning. The marine sanctuary pro- hibits commercial fishing in about 500,000 sq km of ocean. The legislation also requires most for- eign fleets working in the limited fishing area to land their catch in Palau and then pay an export tax. Remengesau said the ban was needed to ‘let the ocean heal’ after years of mass commercial fishing in the Pacific that has seen stocks of some species such as bluefin tuna fall to critical levels.
