With such a limited gene pool, the future of the species did not look healthy. However most of the world’s 2,000-strong Przewalski’s population descends from just 12 wild horses saved from extinction. Przewalski's horse: Could cloning save this endangered species from extinction?įormerly extinct in the wild, the Przewalski's horse has survived for the past 40 years almost entirely in zoos around the world. They can carry up to 150 passengers with the design reducing the strength of waves that can damage the shoreline. Raising the hull above water cuts drag, delivering estimated fuel cost savings of up to 85 per cent compared to conventional diesel-powered ferries, the designers say. With a top speed of 69 kilometres per hour, the vessels will “fly above the water” with underwater wings lifting up like a plane taking off. One of the world’s most advanced electric passenger ferries could soon link Belfast and Bangor in Northern Ireland. Could a ‘flying’ electric ferry be the perfect zero-carbon transport solution for busy cities? Positive environmental stories from September 2022 ‘Soil batteries’: Solar power could one day be stored in the ground beneath our feetĪ plentiful natural resource is being called on by researchers at Cardiff University to help solve the problem of renewable energy storage.Īn “adventurous” new project to create a ‘soil battery’ uses earth’s teeming microbial life to transfer energy - and is one of dozens of bright ideas that has just got a major funding boost from the UK government. “Changing the legal status of beavers is a game-changer for these amazing eco-engineers, which benefit both other wildlife and people,” says Joan Edwards, director of policy and public affairs at The Wildlife Trusts, which has pioneered their reintroduction. It is now illegal to deliberately capture, injure, kill or otherwise disturb beavers in the UK. Beavers are now a protected species in England 400 years after they were hunted to extinction While the government is looking for large-scale legislative solutions, part of the answer could be an old, tried-and-tested recipe: using nitrogen from animal manure in horticultural greenhouses.īy doing so, farmers get rid of their surplus nitrogen and horticulturists use less gas. Dutch flower growers are cutting costs by using cow poo instead of buying gasīetween farming animals and growing flowers, the Netherlands has a high level of nitrogen emissions. Instead, the treats - manufactured by Nestlé - will be wrapped in recyclable waxed paper.
