Social media, magazines and shop windows bombard people daily with things to buy, and British consumers are buying more clothes and shoes than ever before. Online shopping means it is easy for customers to buy without thinking, while major brands offer such cheap clothes that they can be treated like disposable items – worn two or three times and then thrown away

In Britain, the average person spends more than £1,000 on new clothes a year, which is around four per cent of their income. That might not sound like much, but that figure hides two far more worrying trends for society and for the environment. First, a lot of that consumer spending is via credit cards. British people currently owe approximately £670 per adult to credit card companies. That’s 66 per cent of the average wardrobe budget. Also, not only are people spending money they don’t have, they’re using it to buy things they don’t need. Britain throws away 300,000 tons of clothing a year, most of which goes into landfill sites.

People might not realize they are part of the disposable clothing problem because they donate their unwanted clothes to charities. But charity shops can’t sell all those unwanted clothes. Fast fashion goes out of fashion as quickly as it came in and is often too poor quality to recycle; people don’t want to buy it second-hand. Huge quantities end up being thrown away, and a lot of clothes that charities can’t sell are sent abroad, causing even more economic and environmental problems.

However, a different trend is springing up in opposition to consumerism – the ‘buy nothing’ trend. The idea originated in Canada in the early 1990s and then moved to the US, where it became a rejection of the overspending and overconsumption of Black Friday and Cyber Monday during Thanksgiving weekend. On Buy Nothing Day people organize various types of protests and cut up their credit cards. Throughout the year, Buy Nothing groups organize the exchange and repair of items they already own.

The trend has now reached influencers on social media who usually share posts of clothing and make- -up that they recommend for people to buy. Some YouTube stars now encourage their viewers not to buy anything at all for periods as long as a year. Two friends in Canada spent a year working towards buying only food. For the first three months they learned how to live without buying electrical goods, clothes or things for the house. For the next stage, they gave up services, for example haircuts, eating out at restaurants or buying petrol for their cars. In one year, they’d saved $55,000. 

The changes they made meant two fewer cars on the roads, a reduction in plastic and paper packaging and a positive impact on the environment from all the energy saved. If everyone followed a similar plan, the results would be impressive. But even if you can’t manage a full year without going shopping, you can participate in the anti-consumerist movement by refusing to buy things you don’t need. Buy Nothing groups send a clear message to companies that people are no longer willing to accept the environmental and human cost of overconsumption.

The seeds in a sunflower exhibit a golden spiral, which is tied to the Fibonacci sequence.

The Fibonacci sequence is a series of numbers in which each number is the sum of the two that precede it. Starting at 0 and 1, the first 10 numbers of the sequence look like this: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, and so on forever. The Fibonacci sequence can be described using a mathematical equation: X_n+2 = X_n+1 + X_n. People claim there are many special properties about the numerical sequence, such as the fact that it is “nature’s secret code” for building perfect structures, like the Great Pyramid at Giza or the iconic seashell that likely graced the cover of your school mathematics textbook. But much of that is incorrect and the true history of the series is a bit more down-to-earth. The first thing to know is that the sequence is not originally Fibonacci’s, who in fact never went by that name. The Italian mathematician who we call Leonardo Fibonacci was born around 1170, and originally known as Leonardo of Pisa, said Keith Devlin, a mathematician at Stanford University. (...)

“Liber Abaci” first introduced the sequence to the Western world. But after a few scant paragraphs on breeding rabbits, Leonardo of Pisa never mentioned the sequence again. In fact, it was mostly forgotten until the 19th century, when mathematicians worked out more about the sequence’s mathematical properties. In 1877, French mathematician Édouard Lucas officially named the rabbit problem “the Fibonacci sequence”, Devlin said. Other than being a neat teaching tool, the Fibonacci sequence shows up in a few places in nature. However, it’s not some secret code that governs the architecture of the universe, Devlin said.

It’s true that the Fibonacci sequence is tightly connected to what’s now known as the golden ratio, phi, an irrational number that has a great deal of its own dubious lore. The ratio of successive numbers in the Fibonacci sequence gets ever closer to the golden ratio, which is 1.6180339887498948482. The golden ratio manages to capture some types of plant growth, Devlin said. For instance, the spiral arrangement of leaves or petals on some plants follows the golden ratio. Pinecones exhibit a golden spiral, as do the seeds in a sunflower, according to "Phyllotaxis: A Systemic Study in Plant Morphogenesis"(Cambridge University Press, 1994). But there are just as many plants that do not follow this rule.
