It is difficult to imagine our life without fast food. It is gradually forcing out the traditional cuisine, and many people are sure that fast food will dominate in the future.

In my opinion, fast food is really the thing of the future. First of all, people’s life is getting faster, and in the future it will require much quicker solutions in almost every sphere. People will have to do things more quickly, including meals. The schedule of most people is becoming tougher, so, eventually, they will not have enough time to eat properly. Fast food will be the best suited for a quick meal. Sandwiches and burgers of various kinds are advertised and sold on every corner, so people cannot resist a temptation of buying one. In the future, the temptation will definitely grow on.

But there are people who believe that fast food will never dominate home-cooked meal because of its harm to the health. It is common knowledge that this kind of food causes serious illnesses, because it is made mostly from artificial substances.

Nevertheless I cannot support the opposing opinion because food production is being perfected at a high rate, and future fast food is overwhelmingly likely to consist of healthy ingredients.

In conclusion, I would like to emphasize the fact that the future is born in the present. If we want to predict what our life will look like in the years to come, we should pay attention to the modern tendencies. As regards our meal, fast food is booming today, which means it will be our basic food tomorrow.

1. Many people aren’t sure that fast food will dominate in the future.

2. People’s life is getting faster and in the future fast food will be the best suited for a quick meal.

3. People who believe that fast food will never dominate home-cooked meal because of its harm to the health.

4. Nowadays fast food is overwhelmingly likely to consist of healthy ingredients.

5. Home-cooked meal of various kinds are advertised and sold on every corner.

6. Fast food is booming today, it means it will be our basic food tomorrow.
