Sandwich Island Saga 69. All Change Here!

There's been a number of articles about coin change machines. They charge both a fee and a percentage of the amount. Only in the US, however. I've seen them offer to change money into cryptocurrency! Take 'em to a bank. They charge nothing!

Full of Beans

Beans are an underappreciated food source. The many varieties of legumes are good for the soil and the atmosphere. They fix nitrogen and remove carbon dioxide. Beans are important sources of proteins, roughage and trace elements. Their production takes up much less space than meat-generating cattle and chickens. Beans also need much less water and don't generate problematic waste.They don't contain fats that damage human health. We should encourage folk to see beans as an important park of their diet. They certainly shouldn't be dismissed as second class food ingredients

Sandwich Island Saga 62. Wind turbines and birds

Research in Norway has revealed that painting one blade of a wind turbine black, greatly reduces the number of bird collisions. This seems a simple way of limiting a detrimental effect of these installations.

CRISPR and Conservation


CRISPR or 'gene editing' is a powerful tool for subtly changing an organism's DNA. Conservationists are generally focused on saving the natural world. Anthropogenic (human) influences are, however, rapidly changing the planet, often making it difficult for organisms to cope. Some Conservationists are now considering using CRISPR to make organisms more resistant. For example, the Crested anole can be given small DNA tweeks to make it better at climbing. Sea birds could be made resistant to bird 'flu. This would mean, however, a nature dictated by one species.

The magnitude of the problem is much greater in Hawaii!

Cardiff and Cars

Cardiff has become the first UK city to increase its parking charges for heavy cars (more than 2400 kg when fully-laden). The description particularly applies to so-called 'Sports Utility Vehicles'. SUVs take up more space than traditional cars. They also cause more damage to road surfaces. These status symbols also generate more pollution via exhaust emissions, braking systems and tyres. SUVs are also more likely to kill or maim other road users. It's likely that the Welsh car lobby won't like any curtailing of their 'freedoms' (they were incensed by the 20mph limit in built up areas).
