NUCLEAR ENERGY

Nuclear energy has got a very bad reputation, but it is the most widely used.

Nuclear energy is more efficient than other types of energy such as fosile fuel. People think it is dangerous. The nuclear waste is more dangerous than a nuclear energy plant. Nuclear waste is active for around 500.000 years. But it depends on the radioactivity degrees. There are three levels: high, medium and low radioactivity. In the first level it is uranium, in the second level is contaminated water, and there are staf in the third level where they are wearing staf´s clothes.

In my opinion nuclear energy is the most efficient and secure. I don´t like it because the nuclear waste. People do not trust nuclear energy, because it has happened many nuclear catatrophes in the world, Three Mile Islands, USA, Chernobyl,Ukraine, although they have been caused by human errors.

No Smoking in Public Places

Some businessmen now say that no one can smoke cigarettes in any of their offices. Some governments have banned smoking in all public places. This is a good idea though it takes away some of our freedom.
As we know, smoking is harmful not only to our health but also to those who are around. Smoking can lead to many diseases, such as lung cancer. Smoking affects non smokers more than it does to smokers. Ratio of passive smokers getting ill is higher than that of smokers. So, many nonsmokers are against smoking.
In public places the harm of smoking is greater. This is connected with another effect of smoking. That is, smoking pollutes environment by giving much poisonous vapour off into the air.
Therefore, that the government ban smoking is necessary and it mmatters to us. It is a measure to protect ours and the other's health. So many people, especially nonsmokers, are in favour ot that policy.
Some people say that it takes away some of our freedom. I think it is a one-side view. If a peson wants to smoke, he may smoke in private, not in the public places. In fact, smokers still have the freedom of smoking. But, I think, smokers had better give up smoking, not only in private places, but also in the public places, and everywhere. It will be beneficial to all of us.

Nuclear VS Renewable Energy

I think nuclear energy is useful fo everyone and it is also an energy that has many disadvantages as it can damage the environment.
On the one hand without nuclear energy we could not have all the technologies that we have now. But nueclear energy can damage the environment in the near future. Although we don't take any notice, but the damage will occur within a certain time and people don't want to cause any harm to their children. Due to the excessive harm of nuclear energy the best option would be to use renewable energy, but today it would be very expensive to use it
