今日のお題：New Electric barrier Repels Sharks.
Summary of the article
Some researcher developed a way to repel sharks.
The way is a new method to keep sharks at bay by using a cable that emits electric current.
The electric current can be effective only for sharks, which are sensitive to electric current because of their special pores around their noses. Therefore, no other fish will not feel electric current and a person who touch a electrode will only feel a sting.
Q: What is your opinion about using electricity to repel sharks?
I believe this is a good tool to keep them at bay because
the tool takes advantage of sharks' traits like special pores, that can sense electric current.
Considering the safety for other sea animals, the way is environment friendly and harmful.
They won't destroy the ecological chain since it doesn't hurt anything.
Q: Do you feel safe if that barrier is available in your country’s beaches?
I rarely hear sharks attack human in Japanese sea. But safe is better than sorry.
Q How else can we ensure safety against attacks of wild animals?
First, we need to know the basic traits of each wild animal. Then we should take precautionary measures. When it comes to a shark, they have a special pores. That's why the researchers was able to develop an appropriate tool to repel sharks.
Q What is your opinion about the humans' killing of wild animals such as sharks?
I think that killing wild animals easily is a selfish behavior. Human is invading their habitat and they have no choice but to move to the city and neighborhoods for some foods.
They don't intend to hurt human at all and they are just looking for food. However, we consider them dangerous enemy and kill them as soon as we find them.
Basically, the earth or planet is not only for human, but also for other creatures. We should recognize how we can share habitat with others.
