Babies love chocolate, and sometimes they also eat the paper around it. My cat enjoys a meal of good, thick paper, old letters, for example . She doesn't like newspapers very much .
Of course, the best paper comes from wood. Wood comes from trees , and trees are plants: Vegetables and fruit are plants too, and we eat a lot of them . So can we also eat wood and paper?
Scientists say: “ All food comes in some way from plants. ” Well, is that true? Animals eat grass and grow fat. Then we eat their meat. Little fish eat sea-plants; then bigger fish swim along and eat them . Chickens eat bits of grass and give us eggs . What food does not come from plants in some way?
Scientists can do wonderful things with plants . They can make food just like meat. And they can make it without the help of animals . It is very good food, too . Now they have begun to say : “ We make our paper from wood . We can also make food from wood . The next thing is not very difficult . ”
What is the next thing? Perhaps it is food from paper. Scientists say;“We can turn paper into food . It will be good , cheap food too : cheaper than meat or fish or eggs . ”
So please keep your old books and letters . One day , soon , they will be on your plate. There is nothing like a good story for breakfast .

Humankind has tried to improve its standard of living since the very beginning of civilization. Back then, as well as today, providing food and security was the basic task for a person. However, nowadays the range of required goods has expanded significantly. People feel the need for not only some primary things, such as a piece of bread and a roof over their heads, but also for various facilities and luxuries. Providing humanity with these things is connected to the use of natural resources, which requires energy. In turn, the common sources of energy we use today cause pollution, so economic growth is almost unavoidably associated with environmental damage.
Economic growth is the increase in numbers of goods and services produced over time by an economy, and it is calculated in terms of real Gross Domestic Product (GDP). Before growth is calculated, inflation (通货膨胀)is adjusted in order to take into account its mis­leading effect on the price of goods and services. Economic growth can also be explained as the increase in expected output, which results from an increase in actual output, or total de­mand.
There are certain aspects of economic growth which affect the environment. The first of these is the fact that in order to produce more goods and products, at a faster rate, the construction of large industrial plants is required. These plants produce a lot of waste, leading to the pollution of water and the atmosphere, which may cause negative long term health effects to nearby populations of animals, or people. They also lead to global warming.
Industrial manufacturing leads to the constantly increasing energy consumption. The traditional energy sources, which are commonly used nowadays, are considered to be the greatest polluters to the environment. There also exist so-called eco-friendly sources of energy. They are sometimes preferred but replacing the traditional sources with them also requires time, during which people have to make some sacrifices to support these undertakings.
In order to produce economically practical energy, a sometimes significant transformation of the natural site is often inevitable. This is expensive and, has harmful effects on the environment. Application of wind energy would block airflows’ natural speed which is the reason for their decrease in strength, after crossing the windmill. Consequently, the pres­sure balance that is brought about by this current will be affected, and it is important to re­member that the environment and weather conditions are directly affected by atmospheric pressure.
For these reasons, bringing about economic growth without any resulting environmental damage, whatsoever, is impossible.
