Stick to the science in science books

My daughter's science textbook says the following: "Corrosion is an undesirable process ..." What sort of nonsense is this? Why is a science book taking sides on whether a natural process is desirable or not?

Corrosion just is. As far as science should be concerned it should be neither desirable nor undesirable. I'm sure a many scientists have earned a good living trying to devise new ways to prevent or overcome corrosion. Was corrosion undesirable to them?

And, what about all those scrapped cars, planes, trains? Don't we 'desire' corrosion for them? Aren't we glad that mother nature will return giant chunks of metal (small pieces too) back to the earth? I just don't understand why such nonsense should be in a school textbook.
