It is commonly known that Japan went from a 19th century national economy to a 20th century global economy in a time span of 30 years between 1945 and 1975. What is less known is that Japan, understanding that fast, efficient transport was the key to a global economy, was the first country in the world to introduce the “Bullet Train”. Kawasaki Heavy Industries was duly appointed the manufacturer and the first high speed train went “on line” in 1964. The Shinkansen, as is known in Japan, made its first journey between her capital and Osaka, a distance of 301 miles, at a speed of 132 mph.

The next country to introduce high speed trains was France. SNGF, the public rail system in France, was losing passengers to other forms of transport and introduced the “TGV” (Train à Grande Vitesse) to counteract the trend in 1981. As a result of Opec controlling the oil market in 1974, the train was designed to be powered by gas turbines. It ran on a specially built track between Lyon and Paris. Eight years later another TGV was introduced, this time between the coast and Paris. Soon, France became the most rail efficient country in the world with high speed train connections to Belgium, London, Germany, Switzerland, Spain and the Netherlands.

_{k    s}There was another positive element that resulted from the introduction of high speed trains. Between 1964 and 1991, Japan’s Shinkansen had transported in excess of three billion passengers without there being a single fatal accident and eleven years after France introduced the TGV, it still had a 100% safety record. This statistic has never been equaled by the traditional slow moving trains in any country.

China has become the fourth country to produce such trains, after France, Germany and Japan. China's first domestically produced bullet train with a maximum speed of 350 kilometers per hour has rolled off the production line. Equipped with highly-efficient power system, the currently fastest train in China is also energy efficient. When the train is running, it can transfer kinetic energy into electricity, so that it can ensure its electricity supply even when it is cut off from the power grids. In all, such trains are expected to be in commercial operation by the end of 2010.

We know that if rivers are polluted with waste products from factories, we’ll die.  43  , in most countries wastes are still put into rivers or into the sea, and there are 44   laws to stop this.

We know, too, that if the 45   of the world continues to rise at the present rate, in a few years there will not be enough food . What can we do to solve these problems? 

If we eat more vegetables and less meat there will be more food available for every one. Land that is used to grow crops   46   five times more people than land where animals are kept. Our natural resources will last longer if we learn to recycle them.

The world population will not rise so quickly if people use modern methods of birth control.

Finally, if we educate people to think about the problems, we shall have a better and cleaner 47    in the future.
