These days, electromagnetic wave left from cell phone make some problems. State of Kalunakata in India, government established children who is under 16 prohibit using cell phone because it is harmful for studying or health. Actually, because of electromagnetic wave, it has been decreasing the nunmer of child. We think this probelem more sseriously because we can not live without cell phone.

I have heard electromagnetic wave emitted from cell phone affects human brain. Also,there is a man who works company and uses cell phone many hours for business in a day. Unfortunately, he became defects of memory and, he can't remember anything which happened 30 minutes ago. For these example, I think cell phone has a bad for health, but I can't live without it so we should be careful of not to use cellphone many hours. From this news, I thought that our life is being convenient, but it is only surface aspect and it has bad side,too. I think it is important to know about both good sides and bad sides of things.
