Every parent wants a perfect child. To achieve this goal, they turned to cloning. However, cloning is not a normal way of life.

Cloning is an expensive process. Cloning is expensive because it is a new technology. Cloning uses many devices, scientists and doctors. Not every family can afford cloning. Therefore, cloning is not a good solution for everyone.

Cloning is abnormal and new. Many people don't understand cloning. If a child is conceived through this process, society may not be ready to accept this. The child may be regarded as a "monster" The whole process may turn into a disaster.

Some people say that people can have a "perfect" child through cloning. You can weave diseases and choose the perfect DNA, such as blue eyes with a gifted brain. However, if everyone does this, we will live in a perfect "artificial world". Everyone will have perfect looks and brains. There will be no balance in the world.

In a word, cloning is an expensive and abnormal process. This will also lead to world imbalance. Therefore, cloning is not a good idea.

Public transportation should be a free service.

Nowadays, cars make it easier for people to travel. However, more cars on the road means more polluted gases are released. At the same time, it will lead to traffic congestion, which is a major problem in all cities. Therefore, the government should formulate some policies to encourage people to use public transport. Free public transport should be included in these policies.

Free public transportation will encourage people to use it. The main reason why many people are not used to using public transport is that it is expensive. Recently, many ordinary people said that they would refuse to use public transport until the cost can be reduced. Therefore, we can see that when public transportation is free, most people will use public transportation.

In addition, free public transportation will solve the traffic problem. Free public transportation will encourage more people to use it; This will reduce the number of cars on the road. Therefore, public transportation will ease the congestion.

However, some people say that free public transportation will mean increasing taxes to pay for it. However, basically, this is not correct. The cost of public transport will be paid by the government that encourages people to use public transport. Therefore, the government will allocate a budget to pay for free public transportation.

In a word, free public transport will encourage people to use public transport and solve the traffic congestion problem. Therefore, public transport should be a free service in China.
