Modern appliances are very different from the ones we used in the old days. Now, we are using appliances such as ovens or purifying machines in our homes. These machines have advantaged us for a long time, but they have failed to completely  replace charcoals, substances which can both purify the world and make delicious foods.

     Appliances we are using thesedays have caused several serious problems. They do work quickly and accurately. However,  they destroy the environment, instead of cooperating with it. Moreover, they emit harmful electronic waves that disturb people.

     Charcoals, on the other hand, have come from the environment and

will go back to it. They rot eventually and become nutritious soil. Moreover, they can benefit us by absorbing electronic waves. They can also make better foods than ovens.

     Recently, people have started to use charcoals again. Many restaurants have begun to cook ducks with them. People have started to place them all over their houses. Few have begun to eat their powders.  We should keep using them so that our decendents can enjoy such versatile thing just like us.
