And pools are not meant for drowning... and yet children keep drowning.
There are inedible and poisonous plants, and you can teach children from a certain age what they are about and how to deal with them. You can also try to eliminate all dangers and create as "safe" an environment as possible. Both strategies are usually "successful," a dispute about it is not worthwhile, I tend to the approach of introducing dangers.
Because the parents do not pay attention...
That accidents happen because parents do not pay attention certainly also exists. To place this alleged negligence as a universally valid reason for accidents involving children is a resounding, unjustified, and heartless slap in the face for all people who have experienced a real tragedy. I write this as
not affected by such a misfortune. I am grateful for that; it is no achievement.
