"I also disagree that providing an environment that is not as safe as could be is good for children"
Your above statement is considered incorrect by virtually all experts in the field. Please see the link below for one article on risk:

Quoting from the above:
Why do children need to experience risk and challenge?
Everyday life always involves a degree of risk and children need to learn how to cope with this. They need to understand that the world can be a dangerous place and that care needs to be taken when negotiating their way round it. Inevitably the most powerful learning comes from not understanding or misjudging the degree of risk. Similarly the toddler who ignores the warning, ?Don?t touch, it?s hot?, and feels what ?hot? means, is not likely to make the same mistake again. Being told about possible dangers is not enough ? children need to see or experience the consequences of not taking care.
If we observe young children, we can see that, from an early age, they are motivated to take risks ? they want to learn to walk, climb, ride a tricycle ? and are not put off by the inevitable spills and tumbles they experience as they are developing coordination and control. In early years settings children find their own, often quite ingenious, physical challenges and, in doing so, learn about their own strengths and limitations.
"Children who are sheltered from risk and challenge when young will not be able to make judgments about their own capabilities and will not be well equipped to resist peer pressure in their later years. Jennie Lindon warns that: ?Adults who analyse every situation in terms of what could go wrong, risk creating anxiety in some children and recklessness in others.? (Lindon, 1999 p10)
Children who learn in their early years to make their own reasoned decisions rather than simply doing what they are told to by others will be in a stronger position to resist the pressures they will inevitably face as they reach their teenage years. In contrast, overprotected children may well make reckless decisions which put them in physical or moral danger."
There are many many studies which link sensible risk taking with better long term psychological and physical outcomes for children. What is important is to conduct a reasonable risk assessment. To go back to my two with a toy dinosaur in the bath, my risk assessment would be that it is a TOY designed for 3+ children, it is thus not that sharp. I will be there all the time (as my wife or I always are when they are in the bath). In the very unlikely event one puts it near the other one's eyes, the reflex of closing one's eyes will protect the eye. Secondly, I will intervene very quickly if I see it about to happen (as I did). If they sit on the dinosaur there may (and I think it unlikely) be a miniscule risk of muscular damage or bruising. This will not last long and they will heal quickly. That was my risk assessment. As to the positives, they know that sharp things can hurt them already, they know that falling underwater is scary and dangerous, they are already mapping meaning on to the word danger and are able to negotiate themselves through "risky" situations. That is modelling real behaviour in the real world.
