Acid Rain
Here we discover the causes and formation of acid rain, how it gets to where it does damage, what that damage is, and what we are doing about it. This is a fine example of a book that teaches as it goes, first establishing basic information and then building upon it. Text and pictures are brilliantly clear, making the book's message available to a wide range of ability and age, and throughout its development the text is reinforced by 'Taking part' things to do and 'Eco-thoughts' to provoke curiosity and further action. As brave new concepts become household words, their original significance may often be lost. So it is with the idea of Acid Rain, and the re-appearance of this excellent primer will be a great help not only to those to whom the idea is new, but to those who know the phrase but not its meaning.
