About terrorism :( I read text and decided to short write a short entry about its main idea. It's terrible...

It’s generally known that one of the most global problems of the modern world is terrorism.
People wrongly concentrated their attention on an unlikely situation such as the possibility of terrorists getting ahold of nuclear weapons, or possibility that our water supplies would be poisoned. Nowadays, technologies are enough developed to prevent it. But real threats which terrorists can do are cheaper and more effective. For example, terrorists can hijack a passenger plane and crash it into a nuclear power station – this situation is such so realistic that American scientists conducted a similar experiment but they used a light plane without passengers. Although the damage was minimal, but if this situation happened in reality, the consequences would be terrible. It could lead to nuclear contamination.
Even worse, it’s not only way what can do the terrorists (?). Biological warfare is one of the cheapest ways to destroy as much as possible  many vital human organs as possible, and thus kill a lot of people.
Chemical weapons are also cheap and easy to get hold of. One study shows us how it can be effective. There was a mock chemical attack on the White House. Dangerous gases were distributed by conditional (?) system through the building. If the President and all of congress had been in the building, they would have been killed.
How can we be sure that a similar situation does not happen in the subway or other public places? A London underground spokesman said that they were carried out special measures not to not allow terrorists to organize attacks. So they installed special equipment, such as cameras, and trained subway staff to recognize unusual smells.
But I believe if common people become more attentive in their daily lives, situations will improve significantly, and it is will not give terrorists opportunities to intimidate us.
