I find the story touching. Unexploded ordnance is a problem mainly for children in former war zones.

Imagine if the park / playground / vacant land where you played as a child was mined and you witnessed others, perhaps your friends getting killed or severely maimed there. Such an issue would weigh heavily on you for a lifetime.

While we can't seem to ban war, many countries have joined a treaty banning landmines. That doesn't help with the ~100M unexploded mines in the world already. This is a bigger problem than one would ever imagine.
