Dung to Death

Fields across Europe are contaminated with dangerous levels of the antibiotics given to farm animals. The drugs, which are in manure sprayed onto fields as fertilizers, could be getting into our food and water, helping to create a new generation of antibiotic-resistant "superbugs".
The warning comes from a researcher in Switzerland who looked at levels of the drugs in farm slurry. (46) .
Some 20,000 tons of antibiotics are used in the European Union and the US each year. More than half are given to farm-animals to prevent disease and promote growth. (47) .
Most researchers assumed that humans become infected with the resistant strains by eating contaminated meat. But far more of the drugs end up in manure than in meat products, says Stephen Mueller of the Swiss Federal Institute for Environmental Science and Technology in Dubendorf. (48) .

Some 20,000 tons antibiotics are used in the European Union and the US each year. More than half are given to farm-animals to prevent disease and promote growth. But recent research has found a direct link between the increased use of these farmyard drugs and the appearance of antibiotic-resistant bugs that infect people.
42．______But far more of the drugs end up in manure than in meat products, says Stephen Mueller of the Swiss Federal Institute for Environmental Science and Technology in Dubendorf. And manure contains especially high levels of bugs that are

To swim across the English Channel takes at least nine hours. It’s a hard work and it makes you short of breath. To fly over the Channel takes only twenty minutes (as only as you’re not held up at the airport), but it’s an expensive way to travel. You can travel by hovercraft if you don’t mind the noise, and that takes forty minutes. Otherwise you can go by boat, if you dreams of being able to drive to France in his own car. "Not possible", you say. Well wait a minute. People are once again considering the idea of a Channel tunnel or bridge.
This time, the Greater London Council is looking into the possibility of building a Channel link straight to London. A bridge would cost far more than a tunnel, but you would be able to go by rail or by car on a bridge, whereas a tunnel would provide a rail link only.
Why is this idea being discussed again Is Bri
A. Swimming across the Channel takes less than four hours.
B. The idea of a Channel tunnel or bridge is a very new one.
C. It is considered to be more difficult to swim across the channel than any other means.
D. A tunnel or bridge would only reach as far as the coast.
