I wrote about Cars as public utility in last week. So I wrote about the advantages of cars until last week. But cars have not only good points but also bad points. And this number is not little and can't solve easily now. So it is threatening our daily lives just now. Please think about problems following next.
1. The accidents by the car
It is right that cars can run so fast and cars is so useful. But if the car collide with the car or the people, this damage is not light for cars and people. So this serious accident's number is so many in recent. The numbers of accidents that is caused from January to November in 2012 is about 600,000!! It is so surprise and awful. This number is decreasing comparing with the number of accidents from 2000 to 2010. But the accident not fade out from our world.
2. global warming and air pollution
Now most of cars run by gasoline. So cars exhaust harmful gas. For exsamples, Carbon Monoxide, hydro Carbons, nitrogen oxide, Particulate Matter and carbon dioxide. These gas causes many problems. For exsample, global warming and air pillution,etc ... Carbon dioxide involves global warming. And Carbon Monoxide, hydro Carbons, nitrogen oxide and Particulate Matter involve air pollution. Now global warming is more serious problem than other problem. The average temperature of the earth rose 1~2℃ until now. And the influence is not only it but also others. For exsample, rising sea level, the frequency of abnormal climate and the damage of food production. These are not easily thing. All things squeeze our lives.
3. The solution
I introduced many problems and the influence by cars. But people didn't do some solutions until now.
First, I write about the solution for the accident. Recently, we developped EyeSight. It is the systems that prevent crash on driving. It can sense walker and other cars and brake automatically. But it don't popularize around the world now.
Second, I write about the solution for global warming and air pollution. We are developping electrical cars and hybrid cars. These cars run by not only gasoline but also electricity or hydrogen. So it can reduce the discharge of harmful gass.
Finally, I introduced the solution that practiced by public institution or companies. But we can do measure for some problem. For exsample, you use cars when you need cars, concentrating driving always.454
What did you think about some problem of cars? These problem is caused by our driving. So it is matter that all we notice it. So in next week, I will study and write about the license of cars. I will be happy if you read it too. So Good-by to next blogging!!
