The medical stalls in African markets frequently sell tablets made of different sorts of clays, appropriate to different medical conditions. Africans brought to the Americas as slaves continued this tradition, which gave their owners one more excuse to affect to despise them. Yet, as Dr Engel points out, Rwandan mountain gorillas eat a type of clay rather similar to kaolinitethe main ingredient of many patent medicines sold over the counter in the west for digestive plaints. Dirt can sometimes be good for you, and to be “as sick as a parrot” may, after all, be a state to be desired.

Dr. Engel has been working on animal selfmedication research for 10 years.2. Animals often walk a considerable distance to find plants medication.3. Birds, like Macaw, often eat clay because it is part of their natural diet.4.

One piece of evidence particularly deals with10___, a soilconsuming behavior monly found across animals species, because earth, often clay, can neutralize the 11____content of their diet. Such behavior can also be found among humans in Africa, where people purchase 12__at market stalls as a kind of medication to their illnesses. Another example if this is found in chimps eating leaves of often 13____taste but with no apparent medicinal value until its unique structure came into light. A.

Or in Charlie Paton’s case, out of the rain. “ I was in a bus in Morocco travelling through the desert,” he remembers. “It had been raining and the bus was full of hot, wet people. The windows steamed up and I went to sleep with a towel against the glass. When I woke, the thing was soaking wet. I had to wring it out. And it set me thinking. Why was it so wet?”The answer, of course, was condensation. Back home in London, a physicist friend, Philip Davies, explained that the glass, chilled by the rain outside, had cooled the hot humid air inside the bus below its dew point, causing droplets of water to form on the inside of the window. Intrigued, Patona lighting engineer by professionstarted rigging up his own equipment. “I made my own solar stills. It occurred to me that you might be able to produce water in this way in the desert, simply by cooling the air. I wondered whether you could make enough to irrigate fields and grow crops.”Today, a decade on, his dream has taken shape as giant greenhouse on a desert island off Abu Dhabi in the Persian Gulf the first mercially viable Version of his “seawater greenhouse”. Local scientists, working with Paton under a license from his pany Light Works, are watering the desert and growing vegetables in what is basically a giant dewmaking machine that produces fresh water and cool air from sum and seawater. In awarding Paton first prize in a design petition two years ago, Marco Goldschmied, president of the Royal Institute of British Architects, called it “a truly original idea which has the potential to impact on the lives of millions of people living in coastal waterstarved areas around the world.”The design has three main parts (see Graphic). The greenhouse faces into the prevailing wind so that hot, dry desert air blows in through the front wall of perforated cardboard, kept wet and cool by a constant tickle of seawater pumped up from the nearby shoreline. The evaporating seawater cools and moistens the air. Last June, for example, when the temperature outside the Abu Dhabi greenhouse was 46176。c, it was in the low 30s inside. While the air outside was dry, the humidity in the greenhouse was 90 percent. The cool, moist air allows the plants to grow faster, and because much less water evaporates from the leaves their demand for moisture drops dramatically. Paton’s crops thrived on a single litre of water per square metre per day, pared to 8 litres if they were growing outside. The second feature also cools the air for the plants. Paton has constructed a doublelayered roof with an outer layer of clear polythene and an inner, coated layer that reflects infrared light. Visible light can stream through to maximise photosynthesis, while heat from the infrared radiation is trapped in the space between the layer, away from the plants. At the back of the greenhouse sits the third element, the main waterproduction unit. Just before entering this unit, the humid air of the greenhouse mixes with hot, dry air from between the two la
