Protecting the Apple Trees

In Chihuahua, Mexico on our recent trip, we drove through the apple orchard region. I was interested to note that there were special nets installed to protect the apple trees from hail, some already spread out, others ready to be spread upon warning. Later that day, we realized it was the right season, when rain and hail fell. There were also heaters near groups of trees, which we learned were lit at times when a frost could destroy the early blossoms or fruit.
It made me think of how we need to take extra measures to protect children, and baby Christians too, from those things that could harm them unnecessarily when they aren't able to protect themselves.
