The story of tea begins in China. According to legend, in 2737 BC, the Chinese emperor Shen Nung was sitting beneath a tree while his servant boiled drinking water, when some leaves from the tree blew into the water. Shen Nung, a renowned herbalist, decided to try the infusion that his servant had accidentally created. The tree was a Camellia sinensis, and the resulting drink was what we now call tea. It is impossible to know whether there is any truth in this story. But tea drinking certainly became established in China many centuries before it had even been heard of in the West. Containers for tea have been found in tombs dating from the Han Dynasty (206 BC—220 AD) but it was under the Tang Dynasty (618—906 AD), that tea became firmly established as the national drink of China.
It became such a favourite that during the late eighth century a writer called Lu Yu wrote the first book entirely about tea, the Ch’a Ching, or Tea Classic. It was shortly after this that tea was first introduced to Japan, by Japanese Buddhist monks who had travelled to China to study. Tea received almost instant imperial sponsorship and spread rapidly from the royal court and monasteries to the other sections of Japanese society.
So at this stage in the history of tea, Europe was rather lagging behind. In the latter half of the sixteenth century there are the first brief mentions of tea as a drink among Europeans. These are mostly from Portuguese who were living in the East as traders and missionaries. But although some of these individuals may have brought back samples of tea to their native country, it was not the Portuguese who were the first to ship back tea as a commercial import. This was done by the Dutch, who in the last years of the sixteenth century began to encroach on Portuguese trading routes in the East. By the turn of the century they had established a trading post on the island of Java, and it was via Java that in 1606 the first consignment of tea was shipped from China to Holland. Tea soon became a fashionable drink among the Dutch, and from there spread to other cent. Suddenly legal tea was affordable, and smuggling stopped virtually overnight.
Another great impetus to tea drinking resulted from the end of the East India Company’s monopoly on trade with China, in 1834. Before that date, China was the country of origin of the vast majority of the tea imported to Britain, but the end of its monopoly stimulated the East India Company to consider growing tea outside China. India had always been the centre of the Company’s operations, which led to the increased cultivation of tea in India, beginning in Assam. There were a few false starts, including the destruction by cattle of one of the earliest tea nurseries, but by 1888 British tea imports from India were for the first time greater than those from China.
The end of the East India Company’s monopoly on trade with China also had another result, which was more dramatic though less important in the long term: it ushered in the era of the tea clippers. While the Company had had the monopoly on trade, there was no rush to bring the tea from China to Britain, but after 1834 the tea trade became a virtual free for all. Individual merchants and sea captains with their own ships raced to bring home the tea and make the most money, using fast new clippers which had sleek lines, tall masts and huge sails. In particular there was a competition between British and American merchants, leading to the famous clipper races of the 1860s. But these races soon came to an end with the opening of the Suez Canal, which made the trade routes to China viable for steamships for the first time.
AIt seems biodiversity has become a buzzword beloved of politicians, conservationists, protesters and scientists alike. But what exactly is it? The Convention on Biological Diversity, an international agreement to conserve and share the planet’s biological riches, provides a good working definition: biodiversity comprises every form of life, from the smallest microbe to the largest animal or plant, the genes that give them their specific characteristics and the ecosystems of which they are apart.
BIn October, the World Conservation Union (also known as the IUCN) published its updated Red List of Threatened Species, a roll call of 11,167 creatures facing extinction – 121 more than when the list was last published in 2000. But the new figures almost certainly underestimate the crisis. Some 1.2 million species of animal and 270,000 species of plant have been classified, but the well-being of only a fraction has been assessed. The resources are simply not available. The IUCN reports that 5714 plants are threatened, for example, but admits that only 4 per cent of known plants has been assessed. And, of course, there are thousands of species that we have yet to discover. Many of these could also be facing extinction.
CIt is important to develop a picture of the diversity of life on Earth now so that comparisons can be made in the future and trends identified. But it isn’t necessary to countries in continental western Europe, but because of its high price it remained a drink for the wealthy.
Britain, always a little suspicious of continental trends, had yet to become the nation of tea drinkers that it is today. Starting in 1600, the British East India Company had a monopoly on importing goods from outside Europe, and it is likely that sailors on these ships brought tea home as gifts. The first coffee house had been established in London in 1652, and tea was still somewhat unfamiliar to most readers, so it is fair to assume that the drink was still something of a curiosity. Gradually, it became a popular drink in coffee houses, which were as many locations for the transaction of business as they were for relaxation or pleasure. They were though the preserve of middle- and upper-class men; women drank tea in their own homes, and as yet tea was still too expensive to be widespread among the working classes. In part, its high price was due to a punitive system of taxation.
One unforeseen consequence of the taxation of tea was the growth of methods to avoid taxation—smuggling and adulteration. By the eighteenth century many Britons wanted to drink tea but could not afford the high prices, and their enthusiasm for the drink was matched by the enthusiasm of criminal gangs to smuggle it in. What began as a small time illegal trade, selling a few pounds of tea to personal contacts, developed by die late eighteenth century into an astonishing organised crime network, perhaps importing as much as 7 million lbs annually, compared to a legal import of 5 million lbs! Worse for die drinkers was that taxation also encouraged the adulteration of tea, particularly of smuggled tea which was not quality controlled through customs and excise. Leaves from other plants, or leaves which had already been brewed and then dried, were added to tea leaves. By 1784, the government realised that enough was enough, and that heavy taxation was creating more problems than it was words. The new Prime Minister, William Pitt the Younger, slashed the tax from 119 per cent to 12.5 per observe every single type of organism in an area to get a snapshot of the health of the ecosystem. In many habitats, there are species that are particularly susceptible to shifting conditions, and these can be used as indicator species.
DIn the media, it is usually large, charismatic animals such as pandas, elephants, tigers and whales that get all the attention when a loss of biodiversity is discussed. However, animals or plants far lower down the food chain are often the ones vital for preserving habitats – in the process saving the skins of those more glamorous species. There are known as keystone species.
EBy studying the complex feeding relationships within habitats, species can be identified that have a particularly important impact on the environment. For example, the members of the fig family are the staple food for hundreds of different species in many different countries, so important that scientists sometimes call figs “jungle burgers”. A whole range of animals, from tiny insects to birds and large mammals, feed on everything from the tree’s bark and leaves to its flowers and fruits. Many fig species have very specific pollinators. There are several dozen species of the fig tree in Costa Rica, and a different type of wasp has evolved to pollinate each one. Chris Lyle of the Natural History Museum in London – who is also involved in the Global Taxonomy Initiative of the Convention on Biological Diversity – points out that if fig trees are affected by global warming, pollution, disease or any other catastrophe, the loss of biodiversity will be enormous.
FSimilarly, sea otters play a major role in the survival of giant kelp forests along the coasts of California and Alaska. These “marine rainforests” provide a home for a wide range of other species. The kelp itself is the main food of purple and red sea urchins and in turn, the urchins are eaten by predators, particularly sea otters. They detach an urchin from the seabed then float to the surface and lie on their backs with the urchin shell on their tummy, smashing it open with a stone before eating the contents. Urchins that are not eaten tend to spend their time in rock crevices to avoid the predators. This allows the kelp to grow – and it can grow many centimetres in a day. As the forests
