Why do drowning incidents occur frequently?

Yesterday, I saw a sad news from the Internet that five senior two students in a certain place went swimming in the river and all drowned. Local rescuers salvaged all the bodies of five students, but the parents of the children have not arrived yet.

With the temperature rising, it is very common for teenagers to swim in the river. But drowning accidents always happen. There are several reasons for this:

First, teenagers are insecure about swimming in the river, regardless of the consequences, just trying to be happy for a while.

Second, children don't know how to swim in the waters and take away blindness. Once someone falls into the deep water, his companions will save him. I put my life in because I didn't know the rescue method.

Thirdly, the local area did not indicate the depth of the places where teenagers often go swimming, nor did it say: "It is dangerous to swim here".

Fourth, the lack of family education, turn a blind eye to children swimming together, lack of supervision.

Fifth, parents work outside all the year round, and there are many left-behind children, so grandparents can't supervise them.

All these have led to frequent drowning incidents.

To this end, it is agreed that all localities should strengthen the education and management of drowning prevention for primary and secondary school students, publicize more, and earnestly strengthen the leadership of drowning prevention.

What needs to be particularly emphasized is that the education and management of the guardianship responsibility of left-behind children in rural areas cannot be relaxed for a moment.

Form a situation in which the whole society pays close attention to the management of * * *. In order to fundamentally solve the drowning incident.
