Truth about sharks

Do you know about sharks? You may say 'Sharks are very dangerous animals and we should not go near to them'. But it is not actually true. Let me tell you about it.
Sharks were kings of the sea. But nowadays, sharks are no more kings of the sea because of people. People are killing too many sharks for their safety even if sharks are not dangerous. According to the news, number of people dead by sharks was 12 in 2011. But 300million to 700million sharks have been hunted for people's food or safety. Also, helpful fish are dying because of the sharks' net.
People have stereotypes about sharks such as 'Sharks are dangerous', 'Sharks are bad predators in the sea.' But not all sharks are dangerous. Assume that there are 100 kinds of sharks, least than 30 kinds of sharks have aggression. Actually, if you don't attack them, they would not attack you. They would think you are not their enemy.
Also, sharks are very important in the ecosystem. If sharks are exterminated, ecosystem would be destroyed. Because sharks are the top animals of the sea ecosystem.
Now I will give you some tips to protect yourself from the sharks.
-When you go under the sea, go with more than 2 people.
-Don't wear colorful clothes when go under the sea.
-In case that you meet sharks, don't move and then sharks won't attack you.
Remember they would think you are not their enemy until you attack them.
